I know we have Mesh.flipFaces(true) working on meshes to flip faces and normals.
On material we have sideOrientation to doing similar things but this feature doesn’t flip normals at all.
Just wondering is there a similar function but only filp normals on material end? Or at least flip faces and normals together like what Mesh.flipFaces(true) does. Or any quick approaches doing sth similar.
I actually asked a follow up question here 1 day ago:
My follow up question is related to this topic.
You can use the solution PG as a starting point in the link above. From my understanding, in the solution PG, there just need one more “flip normal at shader” step added after sideOrientation, the rendering result should look correct.
Actually can you give me an example of Material plug in that only flip normal at render time?
I know I can use twoSidedLighting but ran into some issues when I use it in practice. So for my case just trying to find a way enabling the material to flip normal at render time.
