I would like to ask what to do when animation in Blender looks fine but it has artifacts when exported.
I downloaded a simple model from the web and add my armature and create simple walking animation just to learn the basics. But after export to FBX and even Collada file, weird artifacts appeared. It looks like vertices are influenced just by one weight when exported. Here is a photo from the blender and from exported FBX file viewed in some Win10 software (it is no problem of the viewing software, I checked the Collada file in my render engine). I can maybe add that I was not even able to extract the animation from the file in UE4.
I will appreciate any help.
