How create lightmap on big surface?

[lena.lukashova]

I want create lightmap on street village, I want use one texture for big surface, and I want use other texture coordinates. How can I do?

 

Thanks!

Not really an idea what exactly you want to do.
But wouldn't you do it in your preferred 3d program?
So you would do a second UV channel and bake your lights into that channel.

The Unigine Materials support lightmap on the second UV channel.

For the ground, if you use a terrain, you could render the lights/shadows into a texture (if you have the topology in your 3d program) and then use a decal.

On the paper it looks like ultimate solution for generating LODs, but I was trying several versions of Flatiron, and it always had problems with my models. "Atlased" texture was almost always with some problems, or even totally unusable. Maybe because I was using tiling of textures a lot, god knows.

I had far better results with one free plugin to 3ds max, with was able to merge all textures of model (even tiled!) into one atlas (no new unwrapping like Flatiron) and modify UVs of surfaces accordingly. Pitty its developement was fininished long time ago, it is not perfect, sometimes it crashes on random errors.

I never really had problems with the standard tools in max. 

With a little work you can get your results.
