Problem summary
When baking Paint data to the Bump input of a Shader Network, visible seams appear (Ptex only)
Customer reported version
Mari 7.0v2
Customer reported platform
RHEL 9
Steps to reproduce
1) Open Mari. Open a project, or create a new project, with any geometry. Ensure that the Mapping Scheme is set to Ptex.
2) Create a Shader Network (any will do) that has a Bump input. Create a Color node and plug this into the Diffuse/base colour input. Change the colour of the mesh to a darker colour (eg. dark grey) as this will help you see the bump results better.
3) Create a Paint node and plug this into the Bump input. Paint anything.
4) Change the Bump settings on your Shader node so that the Bump strength is higher.
5) Bake the Paint data. You should see seams appearing along with the baked Paint data.
Expected behaviour
The Paint data should bake without revealing seams
Actual behaviour
Visible seams are produced when baking. Workaround
Unknown.
