I always have trouble with uving with good texel density so how do i map uv of different object with correct texel density without combining them i know when i combine them and unfold the TD will be correct but if i unfold them without combining the TD is bad i want seperate objects to bake normal map
If you are using 2018 or newer then in the uv toolkit there is a area that you can get and set the texel density. I set it once for a scene and then I know that all the assets I create will get the same density.
