Description

It has a common chunking visual artifacts that lot's of triangular Translucent overlap once Ribbon's width is big and twisted heavily facing to Camera

It can be fixed by adding more sections on V direction of the ribbon sheet.  The image below shows how multi sections can fix the issue presented in DCC

I did try a Tessellation material but it seems Niagara particle system doesn't support it

 

Steps to Reproduce

Setting width segments in the tessellation settings will now segment a ribbon across the V direction.
