BryceTalkDTE Interactive Tutorial, June 10, 1999
part 4

AuntiAlias: The Diffusion setting (not diffuse color at top, but Diffusion, first part in the section marked value)... will be affected by a new texture source, source B.

So...

Heather: it's also aliased and beautiful again

AuntiAlias: click the B column for Diffusion. Bryce

AuntiAlias: will give you a new texture source, randomly, of course

heh.. it gave the same as before, oasiswave. ; )

but I'm hunting for a texture source in particular.....

welby: same here

3d~?~elf: 2 diff ones

Luie: let me guess we create a darker rock and then use it for the underwater part?

AuntiAlias: Basic > Basic Altitude.. very top of the pop up menu list

Luie, patience! ; )

Luie: yem Mam

eilif: 2 of those

Luie: sorry

welby: got it

technoid: ok

AuntiAlias: not a problem, Luie, I like how your'e anticipating what's next, I just will not feel obligated to speak the next part before I've completely set it up! ; )

3d~?~elf: only 1 basic alt. on mac, 2 on pc

welby: brown rock bad hair day

technoid: yep elf

Yojimbo: use the white to blue one

AuntiAlias: should have blue color to it... blue gradient

welby: ok

eilif: no 2 then

technoid: got it

Heather: can't find popup menu list

Sumo: okay

AuntiAlias: yeah, there are two on Mac, too

welby: all dark brwn

AuntiAlias: yep, it got all dark brown... there are reasons, which I'll explain! : )

Yojimbo: Heather Hit the down arrow button next to the texture name

AuntiAlias: pop-up menu list is downpointing arrow next to texture name...

er...

what Yoj said ; )

Yojimbo: or hit Shift-Click on the button to see a graphical list

Clay: LOL

Yojimbo: hehe

AuntiAlias: now....

what's going on here is this:

teh value of the Basic Altitude (it's the center part, the black white gradient)

is what's driving the amount of diffusion that is showing for the material

and....

technoid: killer!

AuntiAlias: since it's mostly low altitude we're dealing with, we're mostly got dark

so

you have all (I assume) played with the diffusion slider

technoid: yeah

AuntiAlias: 100 is maximum, 0 is none for diffusion

(aack, sorry.. small brain spasm here.... ascii stuttering....)

; )

welby: lol

AuntiAlias: instead of having uniform setting for diffusion, you're having the texture source determine the diffusion setting

and......

technoid: AA, you should write a book (hehe) I know...

AuntiAlias: since this is something driven by Value, we'll be eventually changing our brownstone texture so that it also has what's going on in Basic Altitude....

but that's a few steps down the road

but. for those of you who were wondering about why no alfa for component 1, this is why.. we'll eventually be adding a component 2 and assinging it to value! ; )

but first....

eilif: it's only an hour till I have to get up, keep going... ;)

AuntiAlias: our exploration continues

actually, I'm going to show you a couple more things and then leave it at that... I'm starting to really slow down here : /

JeffP: ?

Luie: ditto

3d~?~elf: k

AuntiAlias: suppose that we could somehow affect things here in the Materials Lab so that the altitude got "pushed down" somehow.....

why, we can! : )

jeffP, your quesiton?

JeffP: My preview show dark on top and light on bottom

is that correct?

Clay: (stretch break?)

AuntiAlias: no, not correct, Jeff... : (

KPT John: (Aunti leaving and turning out light in other rooms Thanx!)

Heather: no, it's my bedtime

AuntiAlias: and yes, a stretch break is called for

Jeffric: JeffP you're using Basic altitude, not Basic Altitude (note capital letters)

JeffP: Oh Sorry...

3d~?~elf: i lept ahead and test render is glass

AuntiAlias: <pours another glass of water>

Clay: get to feeling better Susan:-)

AuntiAlias: folks, I want to get you to a good break-point on this before I completely collapse....

gdmsynth: Thanks for bearing with us Aunti, I'm learning a lot. Sorry you're sick...

AuntiAlias: thanks : )

Clay: We've missed you too:-)

welby: your a real trooper auntie

Clay: just ain't the same around here without ya!

Betty: thanks for doing tonight anyway.

AuntiAlias: oh pshaw! (actually i saved up all my strength for this for today)

Clay: LOL!!

Yojimbo: lol

3d~?~elf: yeah, i've never been as far as the noise editor b4...>g<

Clay: wel get back to work then! LOL!!!!!

J/K

Yojimbo: What Clay said is so true though

Heather: a mind is a terrible thing to waste?

Luie: Auntie I have a question?

AuntiAlias: okay, have we all stretched?

Luie, go ahead

Clay: grunt groan, yeppers all stretched...

Jeffric: someone wake up PJF !

Luie: My rock looks blue on top something I missed or am I not being patient enough

AuntiAlias: oops!

do you have two texture sources up, A and B?

Luie: Yes first is my brownstone next is Basic Altitude but it is blue.

Yojimbo: §

AuntiAlias: sounds like you switched texture source A for B, Basica Altitude, or at least you put the Diffuse Color marker in column B

Yojimbo: oh whoops

AuntiAlias: Going down from top to bottom, you should have this:

Diffuse and Ambient color: Column A (brownstone)

the next four in the color section - nothing, unchanged

Value section:

Diffusion: B Basic Altitude

moving down to Bump Height, column A: Brownstone

rest are all in the columns to the left for "nothing"

3d~?~elf: somehow i missed ambient colour setting

Luie: Thanks I had diffuse instead of diffusion in b

AuntiAlias: so.. Source B ( Basic Altitude) is only used in one place: Diffusion

Luie: your a great teacher

gotcha

AuntiAlias: just put ambient colour in column A

tee hee hee! I spelled colour like you do! :D

damn yankee that I am! : )

Yojimbo: lol

3d~?~elf: tease...

ccasady: Thanks I had diffuse instead of diffusion in B

Also!

AuntiAlias: well, just goes to show that there are no such things as dumb questionsa nd that the likelihood that someone else has the same question is higher than 0 : )

3d~?~elf: changes a lot, not pretty tho

AuntiAlias: k

ccasady: exacitaly

AuntiAlias: yeah, what it means is that you got a dull-looking preview of that brownstone terrain

Heather: ?

3d~?~elf: yup

AuntiAlias: mine looks maybe a teeentsy bit lighter at the top

ccasady: yea, now mine is really dul finally

AuntiAlias: we're the dull rock club!

3d~?~elf: yup ic that

AuntiAlias: Heather?

Heather: I don't see brownstone anywhere in my Materials Lab - should I be somewhere else? Markers are where you said

AuntiAlias: oops

Luie: pull out the rabbit Auntie I just called mine brownstone everyone may have a different name

AuntiAlias: substitute "brownstone" for whatever it is you named your texture when you saved in the Texture Library

Heather: I have basic altitude in yellow and red 1st, then black and white

where should it say that? I named it Rocky brownstone textyure

AuntiAlias: ooops. there are two different basic altitudes

AuntiAlias: wait a second.. lemme clarify two things

Heather: let me look

ccasady: She's got the wrong one

Heather: 1st or 2nd?

eilif: 2nd

JeffP: 2nd

ccasady: Blue-ish one


 

 

AuntiAlias: use shift click on the name Basic Altitude to get picture preview

in LIbrary

pick the one that's got the gradient that's white at the top and that's deep blue at the bottom

also....when I say "brownstone" what I mean is that I'll say the name "brownstone" but what I mean is whatever you named your brown rocky texture

ccasady: "Aunti's Seagull frosting"

AuntiAlias: (oops, sorry about the repitition on say/means there)

Heather: I don't get any color name - only Basic Altitude - and all the scene is blue

AuntiAlias: okay, you foudn the right Basic Altitude.

eilif: but in channel A

AuntiAlias: but where it's assigned is slightly off

Do you have two texture sources showing?

A and B?

Yojimbo: §

3d~?~elf: (tm)

AuntiAlias: that question was for heather, folks! : )

Luie: Pisitivly

Yojimbo: doh

AuntiAlias: Heather? you there?

Heather: well, I have a blue shaded up to white and a black shaded up to grey

and third is all grey, and it says Basic Altitude over it

AuntiAlias: yes. that is the right Basic Altitude texture. That is the texture source

Heather: whew:)))

AuntiAlias: do you have another texture source showing on the right side of the materials lab?

brownstone or rocky brown or whatever you call it?

Luie: in channel A

Heather: oh, that is right; the picture at left is dark blue and med blue sky

I don't want to hold everyone up, especially as you don't feel well, maybe I can review notes tomorrow and straighten me out

AuntiAlias: Heather, do you have two texture sources showing? one for A and one for B?

please follow my questions carefully, I can straighten you out in a pinch, i think.... : )

this is what you should have:

Luie: the rocky one on top and basic altitude right below it?! (the suspense is killing me)

AuntiAlias: two texture sources:

Heather: I don't see anything called texture source

AuntiAlias: I guess Bryce calls them Texture A and Texture B

Luie: THE materials lab has 4 spaces labeled A, B, C, D, those are the texture sources

Heather: In Basic Altitude boxes I have three swatches, blue up to light blue, black up to white and grey; below are worldspace wavy blue black and white wavy and grey

AuntiAlias: on the right hand side, where you see the blue and black gradient

Heather: yes

AuntiAlias: okay, the basic altitude boxes is altogether called Texture A or B or C or D -- depending on where it is located.

I hope it's located at B

eilif: could someone make a quick screen dump for heather?

AuntiAlias: but that whole box is the Texture Source

Heather: I don't see anything that says texture at all

Steve Lareau: Aunti- how can I make my pictures kewl? LOL! Cant believe you're still going... and going.....

eilif: no word, h

gdmsynth: It isn't labeled I believe Heather

ccasady: If you wave your mouse over it, It will say TEXTURE

AuntiAlias: I called them Texture Sources in my book Real World Bryce 2

Luie: the rocky one on top and basic altitude right below it? four channels on the right side of the material lab, two are occupied by your first stone and then the next one is Basic Altitude the third one is a grey C and the fourth on is a grey D

AuntiAlias: so you won't find that name exactly on the Bryce interface

Bryce calls them Texture A Texture B and Texture C and Texture D

Heather: waving my mouse brings up texture name and texture library but doesn't say A or B or C

but there are 3 boxes

Luie: oh well whatever nevermind ,

3d~?~elf: if mouse is over dark grey vertical bar on texture source it says "a, b,c, or d"

AuntiAlias: okay... so there is only one set of three boxes showing?

ccasady: those theee boxes are ONE letter, A or B, or...

Heather: two sets of 3 boxes, second called Wavey

AuntiAlias: okay, now we're getting somewhere.

Heather: but the troops are growing restless; maybe I can pick this up from notes

ccasady: make the second one Basic Altitude

AuntiAlias: is Wavey what you're calling your texture from earlier

top one is Texure Source A....

eilif: http://hjem.get2net.dk/eilif/screen.jpg

ccasady: read the Log Heather

AuntiAlias: make that be the same as the texture you created earlier

Luie: Thank you, sorry

Heather: now I have 2 sets of matching boxes, blue shade, black shade, grey

AuntiAlias: make the top one be the one from earlier.. the chocolate chip cookie dough

eilif: look at link, heather

Luie: eilif, you rock

AuntiAlias: I love how helpful everyone is being! :D

Betty: just keep at it Heather. You'll get it. :)

Heather: ok, I went there and see what it's supposed to be, but how do I get my brownstone in the top box?

AuntiAlias: here's the advantage to saving your textures as you work!

Heather: Everything worked fine this whole trip til now

I did save my brownstone and named it

AuntiAlias: because if something weird happens and you choose the wrong texture inadvertantly, you won't have lost your work.

eilif: just choose both again, but reverse

AuntiAlias: shift click on the name of the texture for the top one....

and get the texture library

find your texture and then click OK. It should show in the top area.

Heather: ok, I'm back to my brown texture in the first box of textures

AuntiAlias: yay! : )

Note for clarification: the three boxes together, the name, and all that stuff are together the texture source. There are four of them, total. A, B C and D........

Betty: :)

AuntiAlias: so...

texture source A (the top box) has the rocky texgure

Heather: yes

AuntiAlias: and the second one, has the blue Basic Altitude.....

and your preview is a dull brown, right?

Heather: all the other boxes here are black

Clay: you still doin alright Susan?

Heather: yes, my preview is brown

AuntiAlias: yes, Clay, thanks! : )

Clay: :-)

AuntiAlias: got a second wind, I guess : )

so!

Yojimbo: Yeah we don't want you burning out the first night:)

AuntiAlias: I think that we're now all together!

the idea is....

PJF88: Thanks Susan, but it's 5:35am here, and I'm dead. Time for work, Jeff. Nite!

AuntiAlias: oops, one last check

Yojimbo: we still need you to explain the rest of the great features next week

Jeffric: bye Peter !

Yojimbo: Night PJ

Betty: nite Peter

Clay: cya

Betty: er.. morning?

Heather: Bye - and I'm sorry

AuntiAlias: For Diffusion, B should be where the marker is

Note: diffusion NOT Diffuse Color

Diffusion is in the middle of the list of material properties

AuntiAlias: k

Luie: thats where we leave off?

AuntiAlias: nope... not yet!

: )

I'm taking a breath!

3d~?~elf: yea!

Luie: (my boss is gonna kill me!)

He's paying for this :)

Clay: breath in breath out

eilif: gotta nother half hour before shower and work! Sun's up

desdanova: wax on.... wax off

AuntiAlias: wehre the value for B is white, you have full diffusion (maximum)

where it's black, you have none

so....

and, in the case of source B, Basic Altitude, the altitude is what's driving what's going on

so....

the matter at hand is this:

is there some way, in the Materials Lab, that we can somehow "push" the white area down to make more "white" in our diffusion map?

we can do that!

with a set of tools called Edit Texture

on the upper left corner of the Texture Source for Basic Altitude, there is a button that is labelled "editor"

click that

tools show up. You can move them around

check for this important thing:

on the right are the letters A, B, C D

you want to make sure that you are affecting B

or the texturte source where basic altitude is

3d~?~elf: b is light orange

AuntiAlias: yep! :D

(others are gray)

Luie: mine is blue

eilif: the B button in Edit Text pop up

AuntiAlias: the letter B on the Edit Texture area is what 3D elf is referring to, Luie...

there are three tools corresponding to what you see in Edit Palette, for resize, rotate and reposition

Luie: I pushed it and it turned blue all others are grey

Yojimbo: Then You should be fine

Luie: ko

AuntiAlias: funkadelic, but we'll take it! : )
