@Rich-O-Brien Gi, thanks for the feedback. So am I able to turn it into a png texture and bend that onto the riser or would i just intersect the face of the pattern onto the tread. UI am essentially trying to get this pattern on the tread to make it light up when I render the whole staircase. How would I reduce the geometry?
Yes, you could make it a png and just texture the riser. You can drive emission at render time using an emissive map.
To reduce geometry I would remove the Z height to leave just flat planar shapes. Then use Vertex Tools 2 Merge by Distance tool to nuke vertices.
