Cheetah Material to Unity3D as Vertex Gradient

Is it possible to manipulate the Cheetah3D Material node editor to produce a gradient shader that is editable in Unity3d. ?

I can get one colour to work at the moment in a standard shader of unity and have tried some node and noodle combinations in cheetah.

Just to clarify, I don't want to use a uv map or a pixel texture for this effect.

I have read that this might be possible in the new beta.
How can I apply to test this feature please?

Version 7b17 does have vertex colors.

First you need to add the Vertex Color Tag to the object.

Then create a material with a State Node with the color output plugged
into the Diffuse Channel and put it on the object so it will render.

Then use the new polygon Brush Tool to paint your colors.

Remember to select the Vertex Tag to see the colors in the view window.

All that said I don't know what this is used for, since I don't create games I guess.
Maybe you can test this out more extensively and explain it to everyone.

Thanks ZooHead!

I assume by your post that I can download the beta and test it. ?

The feature is very old and helps with faking shadows or adding depth of polygons with gradients from one colour to another.

P.S. Thanks for the information, I will need to upgrade to test this feature.

PPS. Where is the Vertex tag. I think I found the other elements. - ahh found it! thanks again.

If I could perform this action without collapsing the mesh, that would be wonderful.

However I am super happy being able to contain this texturing method within Cheetah3d and not have to move out of the software and back in again.

It seems to work better with trigons.

Hi Zoohead,

Yes I rushed my test to the finish line, thanks so much for adding that element.

In the era of the mobile device, you have more polygons than pixel texture to play with so in the game development sense working to that goal saves a lot of work and time in worrying about texture memory or U.V. mapping etc.

Trying to grasp this vertex painting I want to use it to influence my texture map, but I don't have any idea what the node setup should be.
I've been trying but haven't had any success. The texture is a dark wood grain jpg image.

I don´t think this makes too much sense as vertex colours - as the name suggests - is based on vertices - which means at least geometry. Not sure what you have in mind as a result regarding your image texture as you need to bake&mix it - which might be easier with a painted image texture to have some kind of control. Ideas?

Cheers

It works best with simple triangular polygons.
It works on the junction points (vertices).

You use the polygon tool Brush set to color.
You can also choose a second color called the
clear color because when you hit the Clear
button it will clear to that color.

With an image you must set the mix to less than 1,
and the Vertex Tag must be selected to see and paint.

Way cool Zoo. Thanks Don't know how I'll use this but at least now I can.
Thanks to you too Frank. I just wanted to know how to use it.
In the last two examples I used only quads I also tried tris 1st. example works like Zoo said.
The closer the loops the sharper the line.
Last example Baked texture
