About lightmap

Hi. Anyody knows what diferences would be if I use a bitmap size 1024x1024 and the lightmap is 512x512? I know I should figure out this by nmyself but I´m busy now.

What do you mean specifically?

Do you mean the diffuse texture is 1024 x 1024 and the lightmap texture is 512 x 512?

Or are you asking the difference between a lightmap being 1024 x 1024 vs. 512 x 512?

The first thing
Diffuse texture 1024x1024
lightmap 512x512

There shouldnt be any issues with it. Lightmaps can be smaller than diffuse textures because their resolution isnt as critical for finer details.

Thanks. That was I needed to know.
