Hi, some lightmaps like Transit lightmaps have a very poor resolution and in some place the aliasing is ugly, for example here:
In can do some antialiasing offline, I just have to resize the lightmap (lik doubling it) using a sharp interpolation algorithm, then I got that:
x2 with LanczosSharp:
x4 with LanczosSharp:
It's not a good idea to do that an all textures blindly, because you can get issues like that on lightmap edges:
So, is it safe to have one lightmap with 256x256 resolution when all other lightmaps have a 128x128 resolution? Currently it works, but is it safe?
