Alias rendering problem

[steve-dorsey]

Hello,
could someone please tell me; why don't all surfaces render in Alias sometimes? I can see them all on the model, but when I render, some surfaces just don't show up.
Please help; --thank you!!

Did you examine ever your Render stats?
you find it in the menu:(WINDOWS/INFORMATION/RENDER STATS) Examine the parameters "Doble sided" and "opposite".. ..

sometimes imported trim surfaces don't work in the renderer. try untrimming and retrimming and see if tgl shade has issues with the offending surfs.

also, try switching tesselators in the Render Globals then seeing if the renderer/raytracer shades the bad surfs.
