Why does this happen when I merge an image with a 3D object?

Question

Hi. I am experiencing an issue with the 3D features in photoshop 22.2 on my M1 mac. I am working with a .OBJ file and merging down reference images, however, as soon as the texture is projected onto the 3D mesh, there is a problem with the pixels getting mixed with the 3D structure around the mouth corners. I have tried but not been able to solve the issue. Any help would be much appreciated.

From the limited info I can see in your screenshot, you will need to either adjust the mesh or warp the projected image. To warp the image open it as a flat texture and use puppet warp to move just the corners of the mouth, using the UV as a guide. To be honest though, I would not use Photoshop for this. The 3D functionality in Photoshop v22 was limited, often unreliable, and is now discontinued. Adobe Substance Painter has much better tools for this job.
