Feature Request: Mesh-Guided Color Painting Tool
I’d like to propose a new painting feature and will explain it through an example.
I used the tool at https://bumpmesh.com/ to generate a textured version of a basic pot. My goal is to paint the extruded sections to achieve a specific visual and structural result: eg this:
Initially, I used the Modifiers + Assembly workflow to align the modified (textured) pot with the original model. I then applied color changes using the original pot as a modifier. However, the resulting sliced model is structurally weak because the colored sections are not interlocked with the base material. Enabling beam interlocking does not sufficiently resolve this issue.
As an alternative, I used the Paint Fill tool. This approach produces a much stronger result, as the painted regions integrate better with the model. However, painting—even when using the edge fill tool—is quite tedious and time-consuming
Suggested Improvement
I propose adding a mesh-guided fill tool with the following capabilities:
-
Allow a separate mesh to be used as a guide (or mask) for selecting triangles to paint.
-
The tool would automatically select triangles that closely match or overlap with the guide mesh geometry.
-
Include an option to invert the selection (i.e., select everything outside the mask).
Benefits
-
Significantly reduces manual painting effort
-
Improves precision when working with complex geometries
-
Produces stronger, more structurally integrated results compared to modifier-based workflows
