How to fix tiling seam on UV shell borders? Advanced issue.

germanager

Hi,

It's more of an advanced texturing question.
I'm coming from prerendered production where we would bake tiling map, create a mask for the UV shell border and paint it out in Mudbox / Bodypaint / Mari  and then apply it on top of the tileable texture fixing the issue.

Is this method used in Unreal or everybody just ignores tileable seams on rocks and props? I don't want to use this technique as it laborious, not  too adjustable, not scalable, and performance expensive.

Maybe you guys are using world coordinates for seamless tiling. I don't know.

I've attached an image.

I don't see how this is an advanced question. Tiling a texture is really low-level for game artists, it's a basic skill. What's wrong with making your textures seamless in Photoshop?

With the rise of procedural texturing tools like Substance, Megascans, etc., textures come out of these tools already tiled.

But if you're using photo source textures, or random textures off the web, you'll need to tile them yourself.

Pardon me if I misunderstood the question.

Also, it is good practice to hide seams where possible. In your example above there is no need for the seam around the circumference.

Layer Cake is great for making things tileable in Photoshop, many are using Substance Painter nowadays as well, it allows cloning etc. on several material channels at once.
