Marmoset Toolbag 2 Problems with seams.

The_Silent_One

Hi,

Whenever I zoom out in the viewport seams apear but when I zoom in they disappear. I'm not sure what is going on?

I fixed the problem. In Photoshop all the maps had a mask applied so the areas outside the uv shells were maked off. Upon exporting, it generated a solid colour for the areas outside the uv shells and this caused the seams. If you have a problem like this and want me to elaborate just message me.

Hello, im having the same issue as you mentioned... How did you solve this? Thank you.

The problem is caused by mip-mapping. As you zoom out, a lower resolution texture is used.

The way to solve this is to make sure all of your maps have pixel padding or a solid background that is similar to the color of the texture. Otherwise you'll get errors along the UV seams with the mip maps.

Joe, would you recommend leaving a little bit more space inbetween UV shells to accommodate for this issue? I usually use Moderate passing but pack the UV shells real tight for my Artstation pieces but in a game environment this might cause issues?
