Question by 0tacun · Mar 07, 2014 at 11:51 AM · shader lightmap uv ambient

Using second UV as Lightmap. Slow?

Hi there,

I created a shader which uses the second UV channel with a prerenderd ambient occlusion image. Unequal to the builtin-lightmap-bumped-shader it does receives light from another lightsource.

My question is simply: Is it expensive to use the second UV channel?

Best
