Chaos Corona for Cinema 4D => [C4D] I need help! => Topic started by: tshelton on 2020-02-13, 00:53:00

I am having an issue with these curtains. I rendered it and noticed some really bad faceting. It only shows up when I render, it looks perfect in the viewport. I also tried rendering it with Physical Renderer in Cinema 4D, and it didn't have the issue. I have only seen the issue in Corona. Any ideas what may be going on? When I imported the mesh, it was triangulated. The gray and black curtain are both still triangulated, the white one I ran the untriangulate command and it didn't solve the issue.

try this. apply normal and normal modifiers then smooth auto modifier.
ignore that actually, that's for 3ds max

Have you tried messing around with the Phong tag?

Yeah I messed with the phong tag but didn't have any luck. I deleted it and re added it, I also changed the angle and that didn't help either.

Hi, are you able to share the scene with us via our private uploader?

I have uploaded that file

Thanks for the file. I have looked at the scene and have made a few small changes. I untriangulated all the curtains, selected all the points and then used the optimized command to make sure nothing was disconnected. The phong tag wasn't doing its job so I created a sphere and copied the tag from that to the curtains. Finally, I dropped everything into an SDS modifier to add additional smoothing (this is optional of course). And I get the result as follows:

I'll send you a PM with the updated zip.
