Short description of error
Some meshes have errors under Cycles rendering or in edit mode
Exact steps for others to reproduce the error
1.open Meshbug.blend
2.Change viewport shading to Rendered
or select object "Edit bug", switch to edit
Hi, thanks for the report. I can confirm the problem when "Auto Smooth" is enabled or when the
sharp_face
attribute is present.Did you import this model from other software?
Mesh bugto Cycles: Mesh artifacts when auto-smooth is enabledThe “Render Cycles BUG” object is generated using the lines in the DXF file
The other object is converted from the standard curve
Probably the same as #106134?
Looks identical. But attributes are missing for above file in 3.5
Since #106134 is now fixed, and this report is also fixed for me, will close. (of course feel free to comment again if issues still persist, we can always reopen in such case)
