Lightmap disappearing with CombineChildren

Questions & Answers
1

First let me say I am having incredible fun with Unity and am impressed with how easy it is to use. Thank you so much for the great software!

I used the combine children script (from the standard assets) to combine identical modular components of my level. When I run the game the diffuse texture and lightmap do not show in the render. Interestingly, the bump is still present and specular highlights work properly. All non-script-combined meshes render properly.

The shader of the combined meshes is Lightmapped/Bumped/Specular using a separate map for each channel though only one UV set. There is only one light (distant) in the scene.

Any tips would be appreciated.

Thank you in advance

For some reason any mesh w/o 2 UV sets will render the lightmap black when the combine children script is used. So you need to add another UV-set to your meshes (even though you dont need them).

I'm having the same problem. When I use the combine children script, my lightmap goes away. I tried making 2 UV sets, I've tried checking the "Generate Lightmap UVs" in the import options. Yet nothing works. I haven't been able to find an answer to this.
