UVs not working in custom display mode
Version (affected)
Rhino 9 WIP — BETA (9.0.26195.12303, 2026-07-14)
Windows 11 environment
Video Report
Summary
UV mapping visualization fails to update in custom display modes when the assigned material is not PBR. Works correctly in default shaded mode and when material is switched to PBR or has an image texture added. Switching display modes or materials does not refresh the UV checker properly.
Steps to Reproduce
- Use any model with existing UV mapping (Look video).
- Create a custom display mode that references a material with texture on the color channel.
- In the layer, there must be no material, so it uses the default or any non-PBR base material.
- Make new UVs (Unwrapping)
- Switch the viewport to the custom display mode.
- Observe that the texture is not applay using the update UVs and use the old ones.
Actual Result
UV checker stops updating or displays incorrectly. Temporary fix by switching to PBR material or adding an image texture. Reverting the material breaks it again.
Expected Result
UV mapping visualization should update and display correctly in any custom display mode.
