Back Faces Rendering Question

Morgan's icon

I'm getting some weird rendering with this patch where the back faces sort of slice out as they rotate. What in the rendering pipeline causes this? Is there a setting I'm missing in order to draw the inside consistently?

Thanks:)

I consulted the tutorial 33 on blendmodes, and the backface slicing effect is still happening even when I get semi transparent or full alpha on the front faces. Interestingly, when I set @cull_faces 2, the artifact goes away and all of the back faces display totally consistently.

I would like this striped shape to intersect with other geometry going around, so the @depth_enable 0, @layer x approach is less desirable. Using two meshes to display front/back separately is getting closer to what I'm looking for though.

Any other tips?

using two meshes with front / back culling enabled is the solution. you can parent them both to a single jit.anim.node object for convenience with spatial transforms:

OK thanks Rob.
