anyone have an idea how to make the brown and the white surfaces blend nice? i've been messing around with this for an hour and I am not getting ANYWHERE

go into vector paint in modeler and add a colour map to the white surface,
just spray the brown to the area you want.
then add the colour map in the surface panel to the white surface
easy :cool:

you can also do it with a weight map but that's a longer story :)

also you could add a null in layout and use a gradient using distance to object and use a brown colour value or even the brown sirface with a good fall off value

would be afew others but that's all i can think of for now :)

make just one surface (brown), and create a weight map (aprox. white surface, 100% value). In surface editor-color make the gradient (input param. weight map), set the color to white and put the alpha to 0% when the weight map value is equal to 0%. Think this may work.:thumbsup:

Is that right? The way the wm is set up., anyhow.

07-07-2003, 01:07 AM
That's not the idea. You should make the wm from the left corner to the extreme of the white surface (right extreme). Hope I can express myself in a better way, I know my english-spanish writing style is awful.:rolleyes:

Here's a very clear tutorial on how to do this Vertex Color Map thing:

argh. i still can't get it to work.

vertex paint should work without a problem
using weight maps in surfaces are tricky, there are alot of things you need to know to get it working

please drop the weight map idea if your a newbie
Vertex paint all the way :buttrock:
that's why it's they :beer:

OK, let's make it step by step::applause:
1- Create JUST ONE brown surface for the skin. We'll call it "skin".
2- Create the w.m.: Select all the polys of the horn (is it a horn?) leaving some space in the right extreme. Then meke the w.m. calling it "horn".
3- Switch to Layout, open Surface Editor, Color Texture, and change it to gradient.
4- Change the input parameter to w.m. and select the "horn" w.m.
5- The lower value should be -100% and the higher 100% by default, so let's make a key at 0%
6- For the 100% value set the alpha to 100% and for the 0% set it to 0%. Color it white, or whatever you like for the horn.
That's it!:beer:
Change w.m. values or create more gradient keys in order to obtain a smoother effect or a more agressive one

so you mean make the horn and the skin one surface?

07-07-2003, 01:54 AM
Weight Maps are cool because you can use them (the "horn" one, for example) to change surface parameters, just aplying them to other param. like bump, or specularity. Learn to use them as quick as you can, they will save you a lot of time!

That's it, just one surface.

Thanks! :)
