Answered: What is causing these seams?

trojanfoe

Newbie alert!  I am a programmer, so I'm well out of my depth with this stuff, however I want to put together some basic models using MODO Indie 10.0 and Quixel Suite 2 (2.2.1PR3) and have done a quick test.  I am getting the following seams and I wonder if anyone can suggest what the issue is?



This is what it looks like in Unity (note the dull gold edges, but that's another issue...):



Here is my complete Quixel project (Dropbox 53MB).

Thanks in advance for and light you can shed on this!

Without downloading your project, it's likely due to your ID map having gaps between those two materials.

The materials are fine in MODO, so could it be caused by baking the color id map using anti-aliasing?

Very much could be, actually. Try it without AA to see if that helps.

Yeah I think that was probably it!  It looks much better, thank you!
Shininess issue easily solved by adding a skybox, of course (as seen in another reply here).
