Thank you very much for your efforts. If I make a texture already in blender on the object, so I should take for the LM the same resolution, or what do you mean with target resolution? What if I do the texture in UE4 myself like the walls? Which resolution for the uv grid should one choose? I’m doing two uv channels. If I do not have image texture for unwrapping, I still need to make a uv mapping.
What was also important to me: if I make an LM of, for example, 256x256 (in blender) which maximum resolution is possible in UE4 without the lightmaps to re-generate? With re-generate I mean under the static mesh editor - LOD - build settings? I import the fbx object and only under general settings I adjust the size. I have already had an object in blender with 64x64 resolution of the LM and under general settings the value set to 1024. Should this be done at all? That’s why I asked at the beginning, whether the resolution of, for example, blender can only be doubled once or several times?
I did not understand the first paragraph. But not for practice. what do you mean with correct proportion. If I put the lightmaps in blender in the uv reaum runterskalliere, they fill the uv space no longer. I can not scale in blender the entire uv space. In 3ds max, this uv space seems to be more abstract. In blender I must enter a resolution to generate this uv space. I’m talking about the LM all the time. I can not scale the grids on different objects without scaling within the specified uv space. That means, the uv space is not used optimally. Maybe I understand something wrong. I guess I do not understand something basic …
I’m trying to explain my problem again with the pictures. It is a very big work effort with adjusting the grids
1- mapping for LM on the largest object as reference. (You can not go beyond the 0-1 uv space)
2- try to map without texture. Grids do not end with scrolling, therefore unsuitable
3- I need to generate a uv space again, specifying the resolution and color grid, because you see the individual pixels or “lines”. The grids are visibly smaller than the first. Not so good with sun shadows on common objects I believe.
4 then I try to adjust the grids by scaling the entire layout. I could now estimate and choose a smaller map (resolution). That does not fold however with several different sizes.
Maybe I think too complicated. greetings
