Lightmapping Question

Unity Engine
1

I’ve run into a snag. I have my test mesh set up in unity, with wonderful water effects, a few trees, and realtime shadows.

Unfortunately the realtime shadows aren’t perfect for this mesh, as light bleeds in. And also in the interest of performance (even though it’s a small scene) I’ve decided to try lightmapping.

To best understand the situation, you should know that the mesh has multiple materials.

I see that I can apply the lightmap to each individual material by selecting the lightmap shader. But I have a lightmap that encompasses the whole mesh, not the individual materials. Is it possible to generate a material for the whole mesh in Unity in order to place the lightmap, which is for the whole mesh?

Sounds like you need another UV set for your main mesh. You’ll need to make one in your 3D app, presuming it can export multiple UVs.

I don’t know exactly what the alchemy is, but you’ll then need to make sure that the right materials line up with the right UV set in Unity.
