Title: Only shadows in the first frame of animation
Post by: lowlandet on 2023-04-27, 14:43:55

I am rendering out a image sequence from Cinema 4D R25 with Corona Render Version 10 - Daily Build 3

I am only getting shadows on my first frame of the animation, how is that?

It's a bit hard to tell from just an image. Can you share the scene?

When saving from C4D, can you please use the ''save project with assets'' option to ensure the textures are linked tot he scene? So far, I cannot reproduce this.

Thanks, I've had a look. I seem to be getting the same result. If I manual render frame 1 and frame 5, the shadow is there. If I render the animation, it's removed. This might be related to the morph camera. Have you tried just using a single camera instead?

Apply 'Thicken'. Even 0.001 will do.
In old days was known to happen w/ PTs rendering single sided geo.

Bingo! I can confirm this corrects the issue. Nice catch burnin! :)
