but upon import to Unity, the same ugly artefacts are there again. I tried sculpting another object to see if its just a problem with the other object. Maybe someone that uses 3D Coat for sculpting, and imports this sculpts to Unity could lay out their pipeline and workflow so I can check if I do something stupid somewhere along the way? But as I'm more of a programmer than a 3D Artist, I don't exactly know it must treat it somehow different than blender files. I guess it has to do with the Blender import and the way it triangulates the file. maybe someone has seen something like this before and can tell me exactly why this happens? Or why I don't see similar problems in 3D Coat? Now I am aware that I might reduce the errors by throwing additional polygons at my mesh and changing the UV mapping (there are also ugly seams all over the mesh, which I can't 100% map to the way the UV is layed out as similar problems are unknown to me with Blender Meshes).īut before I do that I wanted to get some people with more expierience to look at the problem. One of the shading errors is marked in Red. How it looks in the paint room (no problems with the shading visible)Īnd Finally after import into unity. I even thought that the triangulation on import might be the issue and did that once in the retopo room in 3D Coat. I tried changing the UV seams, using smoothing groups or not in 3D Coat and on the Unity Import, tried obj, dae and fbx filetypes. The same old weird smooth shading issue pooped up again, this time I could not fix it however. Today I tried to fix a problem with another of my 3D Coat meshes where the normal map was baked wrong, by using additional polygons for some small details to help the normal map. but then the weird seam issue popped up, which I guess is just the normal way smoothing groups works (I guess the edge split IS superiour, at least for use with Unity, only less performant?)
Now, most of the time I could solve the problem by a) using the smoothing groups / calculating the normals in unity, which made the weird smooth shading issue go away with a mesh I imported some months ago. Most of them are connected to two Problems:ġ) Smooth shading generating weird shading for long thin polygons in case these polys are not 100% flat (which happens often during retopo)ġ) Smoothing Groups and the "calculate normals" creating ugly, visible seams along the edges (which does not happen with imported blender meshes as they don't need the smoothing groups -> most probably thanks to the edge split)
The way I use it normally is sculpt in voxels > Retopo > Pixel Paint > Export to obj > Import to unity I used it with another engine last year without having import problems, but since I switched back to Unity (for other reasons) this year, I have more and more import problems with my meshes. Right Cick on the green dot for on screen options also.I am using 3D Coat since almost 2 Years now, so I have quite some experience with it by now. You can enlarge or shrink the image and other options are there as well. Hand paint instead, rotating the model as necessary. Do not use fill, you will get distortions From camera mode. Now you can rotate the model and the texture image does not move. Move it into position and lock the image. This is where you turn tiling on and off. The reason you are getting that seam showing it appears that your texture is most likely not seamless (non-tiling) You are not using 2021 of 3DC so, you must click on Tiling in the tool panel to un-tile the texture. If it is not a a seamless texture then turn off tiling which is appears to be on atm, If it is seamless then use the " Cube Mapping from the drop down list" Then use the fill tool. Is your image seamless? or in other words a tiling texture. So I am making some educated guesses in my reply. I can go by your pictures to try to help.
