Have an arms mesh for a FPS. Sometimes, especially when the arms are moving, I get these little pixels that show up (and disappear) between the gloves and the arms. I am not a 3D modeller but I can say that the gloves and arms parts of the mesh can be individually selected inside Unity.
I attached a print screen to show what I mean.
Why does this happen and how can I fix this? (PS - this happens only when there is something in the background, when there isn’t (just the skybox), then it doesn’t happen).
Are you sure that’s not some kind of psuedo-reflected light due to your environment? In that picture, there are also similar little white pixels on the gunsight and near the stock not only the 2 you circled.
