Question

Stencil not working unless H+V tiling is on, and paints with an offset

Guys, I'm surprised at myself that I am suddenly unable to use stencil. As a thousand times ago, I have a fill layer which I want to reveal only partially, so I add a black mask, a Paint layer under the mask, select a brush and a stencil, and try to paint on it with white color.

 

Nothing is painted unless I select H+V tiling (which I don't want, but it could be a trade-off). However, the painted area is not the one bordered by the stencil, but it's a little bit shifted to some directions. I've tried tri-planar and UV mode for the fill layer, as well as Tangent wrapping and planar (if I remember well the names of the paint layer's modes), with no change in the result.

 

I've recorded a short video. Can you spot what the basic thing am I miss or do wrong? (Substance Painter is up-to-date, and I fight with it on Windows 11.)

 

Thanks,

Gus

A little update, I can paint with the stencil in Projection mode, but I'm pretty confident I didn't need to switch to it in the past for the stencil on a Paint layer under a mask to work.

A quick update on this weird stuff. I had to add a few more meshes to my model so I went to project config and loaded the updated fbx file. 

My texture looked like this before doing so:

 

Then I loaded the updated file, and came to see this (before and after baking, it's the same):

 

Watch those triangle-like shapes. I remember when I could not use the stencil, I gave it several tries, and for one, I used this triangle as a stencil. Then I deleted it, and created the fix on the asphalt using the projection tool and my pen. It is weird that by updating the project with a new FBX file, these stencil paints came back as they should not even exist anymore. As far as I can remember, I even deleted the Paint layer from the mask stack and created a brand new, so I really don't get it how this could happen.

 

I downgraded from 7.4.3 to 7.4.2 and 7.4.1, performed the same procedure, and got the same results. So it must be something with my project file, rather than Substance.

 

At this point I don't even think it's the video driver, it's more like a corrupted file. I feel very sorry for my carefully designed potholes and road fixes. 😞 If you want to help me, you should probably send a few bottles of whiskey.

I'm having the same issue here. In my experience this happens with meshes that share UVs but on different coordenates. Like when you have a duplicate object that share the same UV space but you move the UVs to 1:0 space. I'm still unsure how to fix it other than re-unwrap but that would cause objects that are similar to use additional UV space instead of sharing it. If you were able to find a solution, I'd love to hear it.
