Glitches and Artifacts showing on packaged game

I’ve tried everything! I don’t know what else to do :confused:

Have you placed those meshes with the foliage tool?

Not at all, but technically they are similar: the threes are instanced meshes procedurally generated. From what I read, it seems that’s a general problem with that kind of instancing.

Looking at the video, those colors surely look like world-space vectors, so I would check your materials to see if they aren’t doing anything strange based on an external parameter.

They do look like that, but I don’t know how could that be happening, here’s my material node:

Do you think that textcoord could be messing it up?
