Substance painter need of help

blast3D · Mar 2019

Hello everyone.
I am kinda of a newbie in the 3D modeling world so I am in need of some advice from the community.
I am texturing a model and after I imported my maps (I have made them in B2M) in Substance painter and put them on the model I noticed a problem with it (it is circled in red) and I don't have the knowledge to fix it. I think it comes from the normal map, because when I don't apply it (as seen in the pictures) this problem disappears, but when I open the map in photoshop I can't see a problem with it.
I will be really thankful if you could help me with this.

I know it has something to do with the texture being set to tri-planar projection. Sometimes when you set a texture to this setting, it has a weird stretchy area when at specific angles. Sorry but I don't have an easy solution for you

Depending on how complex your material is, you could either paint over it or add a second material not set to tri planar, add a black mask, and then paint a little bit over the stretched area. I'd suggest asking your problem on the Allegorithmic forum, and we also have an Allegorithmic technical part of the forum on Polycount.

Hi, thanks for the reply

The material is not very complex and the problem is that I can't paint over the stretched area. I tried not setting it to tri-planar, but it still has the same issue. I think it is some kind of normal map problem, but I lack the knowledge to be sure.

Can we see what the normal map looks like?

What do the UVs looks like at those vertices?

Here is the UV set and the normal map. I hope they will tell you more than they do to me

Try hardening the edges where the UV seams are and rebake it.

Sadly, hardening the edges didn't help

But I tested every map and I get this result from the height and normal maps.
From albedo etc. everything seems Ok/

Maybe you are going to be right marco, because looking closer I saw that the model is wrong.
So, I will do some other UV's and hopefully it will help

Well, surely enough with new set of UV's everything is Ok

So, I apologize for the kinda dumb and newbie problem, but you guys are awesome and I thank you all for the support and ideas
