This is a list of things I usually do in Blender before I start texturing, they might help:
- Check hidden objects and hidden geometry (Alt+H);
- Check doubles (Merge by distance);
- Check ngons (Select -> Select all by trait -> Faces by sides);
- Check normals (Overlays -> Face Orientation);
- Check if UVs overlap;
- Check scale.
This is very helpful
Thanks for your answer! It is indeed very helpful, however I have a few more questions - should all objects have applied scale (so that all their scale is set to 1)? Or is it okay if an object has a, lets say, 1.45/2.3/3 scale? About the uvs - what does "non overlapping uvs" mean exactly? Does it mean that the uvs of the whole whole mesh fit in the uv unwrap screen (sorry, forgot the name of that tab) without overlapping each other? What if my mesh, lets say a car, has a lot of polygons with all the objects - the side mirrors, windshields, grilles etc, how can i fit it all the uvs without them overlapping? Also, what type of unwrapping in blender is the best? I dont know much about uvs and I planned to research and learn more about them before uploading any serious work, but I think your answer might make some things easier for me to understand. Thanks!
Applying scale is something that can avoid possible problems for the client, for instance, modifiers will have different behavior in different scaled objects, even if they are the same size in global space. If the client needs a special scale, he will probably do it himself.
The UV part is not a strict rule, it depends on your workflow. Sometimes it makes sense to have overlapping uvs for repeating objects or if you're using tile-able materials. If you are doing unique textures and need to bake things like AO maps, then overlapping uv's might generate unwanted artifacts.
Does that mean that I should always apply the scale of every object?
