Hi
I am pretty new to unity and I am having a problem with what I think are aliasing artifacts. I am not sure what the source of them is : models, camera, lighting? But I suspect it originates from the models. Can this be because of the mesh or materials?
Please let me know if you have any ideas on how to fix this problem, or what I am doing wrong. I am attaching a pic so you can see them.
(note) They move when you walk around,following the seems of the model.

Could be a problem with mipmaps, bilinear filtering, or your meshes having duplicate vertices/edges.
Aha! Well, I knew it did not have anything to do with textures, because it appeared on meshes with only material. I tried welding the seems and removing any duplicate vertices, but that had no effect. I found the answer in the project settings/quality settings. I turned antialiasing up to 16 times and presto, artifacts completely dissapeared. 
That doesn’t sound like a very good solution. 16x antialiasing isn’t going to run on everybody’s system, and it’s probably overkill in most circumstances; you should figure out what the actual problem is and get rid of it in a realistic way. Blurring out the problem isn’t the answer!
