Max not exporting vertex color

Pipeline
1

Just as the title says.

I’m trying to export a static mesh from 3ds max with painted vertex colours but with no success, it always ends up white. Is there any known workaround for this?

This is the output I get (the mesh is a 4x4 quad plane):

<CoordinateSystem> { Z-Up }

…and BTW Hi, I’m new here.

Looks like no one is using max or vertex colors any more…

I tried exporting to dae ant the using dae2egg, I got some colours but not exactly the ones I’ve painted.

Is there a preferred version of collada that works best with dae2egg?

3

It should be compatible with collada 1.4.x.

If you find a bug, please send me a minimal .dae file showing the problem, then I can look into fixing it.

4

Can you send me the max file? So I can test to find the bug.

5

Sure.
Here’s a link:

After converting it to egg I got what I’ve posted here in the first post.

Ok, I fixed the problem. Panda3D exporter doesn’t support vertex color, so I wrote some code to add this feature. Right now I can get vertex color in egg file.
I alreay send the code to pro-rsoft, hopefully we will be able to export vertex color after next release of panda3D.

Here’s the output egg file of the color.max:
