Fabric rendering issues

[fhenaux]

Hello all,

Was after a bit of advice. I'm currently testing fabric materials and have applied a fabric material to a sofa (back rest) but when rendered, the horizontal surfaces render a different shade to the vertical faces. Would anyone be able to let me know what I maybe doing wrong. I have attached an image for reference of what I mean.

Many thanks in advance and Happy New Year.

Check the faces, try view-face style-monocrome and look if there is any reversed faces..

Hi fhenaux,

This might as well be a mesh normals issue.
You should try and 'Soften' the surface normals:
- Select the Group or Component
- Open the SketchUp's Soften Edge tray
- Enable Smooth Normals and Soften Coplanar
- Tweak the Angle slider

Regards,
Konstantin
