Hi All!

  I'm trying to get a mesh to get illuminated correctly. I use a directional light, and a per-vertex color and normal, without a material set in the Appearance.

  No matter how I set the intensity/color of the light, the rendering is the same. When I set a material on the mesh however, the lighting parameters are respected OK, but I cant get the per-vertex color to show when I set a material.
  I'm trying to achieve a nicely shaded high poly mesh representing elevation data.
  What am I missing?

Thanks.

Hi! ,

  Here are 2 snapshots illustrating my conundrum.
  Additionally to those - the shading appears flat when the material is set? Is this normal?

Thanks.

Re: The flatness of the shading was my mistake, I was calling generateFaceNormals on the geometry. But still the material/color/light problem persists...

Just to compare - Java3D renders the same mesh like this (attached).

In Xith3D - I came to these observations:

When material.setLightingEnabled(true) - properly illuminated, but single (material) color.
When material.setLightingEnabled(false) - vertex colors and normals are OK, but the light gets ignored.

Is there a work around for this or am I just not using the API correctly?
Any help will be highly appreciated.

Thnaks.

It turns out that I've missed to set the colorTarget on the material. Setting the color target to diffuse fixed the problem.

Thanks.

Good to know. Thanks for the finish.
