Why is my height map not displaying correctly

[jay_5900]

I'm using the default brickwall layer and terracotta. The height map is not displaying correctly on a plane but somehow is correct on the shirt mesh. Is there any way to fix this? I've already had to uninstall and reinstall because the different concrete textures were not displaying correctly

That is not app installation issue.The issue you're seeing with the height map not behaving correctly on a plane compared to a shirt mesh probably stems from how Sampler interprets surface geometry and material projection. Try this solutions.

1. Projection Settings

• For the plane, make sure you’re using UV Projection (not Triplanar) if the UVs are well laid out.
• If the plane doesn’t have proper UVs, switch to Triplanar Projection to auto-fit the material, which often handles flat surfaces better.

2. Height Map Behavior

• Go to the Material Properties → Height Channel, and verify the intensity and scale.
• On flat geometry, height maps may appear muted unless you boost displacement or parallax settings under the viewer's rendering options.

3. Tiling and UV Scaling

• The shirt mesh might have finer tiling due to its UV density. Try increasing the tiling on the plane’s material to match the shirt’s visual detail.

4. Geometry Density

• If your plane is a simple quad. If you're using height-as-displacement, add subdivisions via your mesh settings in Sampler or externally before import. Otherwise, use the height map as bump/parallax only.

5. Rendering Preview Settings

• Make sure Parallax Occlusion Mapping or Displacement Preview is enabled under the 3D viewport settings. Height map differences might not show up unless these are active.
