Pre Rendered Lights on a Tiled Sprite
« on: October 11, 2014, 09:28:28 pm »
Hello Unikron and fellow forum folk, I have been trying to bake lights (just the light no shadows required) from a point light to a tiled sprite to reduce  memory usage in my game, I have seen several tuts on lightmapping, basically I check the object as static, place all the lights I want to bake, select baking options and bake, from what Ive seen the only component required to do this is that the objects to bake have mesh renderers,  and my tiled sprite does, but when I set the lights, set the tiled sprite as static and bake the tiled sprite goes black and if I disable the lights there is no pre  light on the tiled sprite, my sprite collection generate normals, my sprite collections material is the tk2dlitvertexcolor and the recive lights, what am I missing here?

Thanks.

Hoghs Bossoms and an atom were talking, the bossom mocked the atom because he could not be everywhere and anywhere at once, the atom though about splitting.....BOOM.

You can't bake lightmaps on tilemaps or sprites - these are classed as dynamic geometry. Secondly they dont have a 2nd uv channel that lightmapping requires so it won't really work. Have you tried painting in vcolors to simulate light? That could work I guess. Alternatively if you need more detail you can use a custom shader which uses scaled world unit as uv2, you will then be able to paint in lighting from within photoshop...
