Generating a procedural mesh -- what is needed?

Troubleshooting graphics

Hi all, JME3 newbie here. I’ve been trying to make some custom meshes in code by just making buffers of vertices and indices. This works for a simple textured material. However when I try to use Lighting.j3md, a variety of terrible things happen; the model disappears except at certain rare angles, lighting is all wrong, etc.



I get the impression I need to be generating some other buffers, possibly normals at least? I can find no complete list of what needs to be made for a custom mesh.

Normals and Tangents, ttry the BinominalTangentGenerator class (or similar named)

[java]TangentBinormalGenerator.generate(yourSpatial);[/java]

Yeah, you have to generate a normal buffer to use the lighting material
