i have a texture that wraps around the entirety of the forearm, and i’m trying to figure out how to allow the UV island edges to combine and get rid of the texture split it creates. is this possible?
There’s no simple way to do that. Either you’ll have to doctor the UV image in something like Photoshop so that opposite edges blend together, jump into paint mode, and use the clone brush (this is probably your best bet), or split your arm island into smaller islands, and move them around on the grid so that the seam isn’t as noticeable. It can be done, but it’s a fiddly process.
Also, if you still have the base image you used for that part of the texture, you could make it tile in Photoshop, assign the faces of that arm piece to another material, box project the tiled image onto that, then bake the results down to the original UV. The end results may not be to your liking, but it’s worth a try to see how it turns out.

figured out i could soften/blur the normal and albedo maps in texture paint. Works well enough! thanks either way
