I didn´t work on my project for several days. Time is short, tomorrow I will continue, and I need to modeling about 30 characters
Did you upload quads? Can you share a screenshot of the original to compare + a link to this model please?
my model is from quads in original
I converted 3d model in .3ds format and uploaded to sketchfab
All game engines convert meshes to triangles Sketchfab
either. Try to use smoothing groups in your 3D soft. and in FBX export dialog check export smoothing groups.
Maybe it helps.
Thank you! I will try
