The towels are pretty poorly modeled with co-planer faces yet they render fine.
The mirror reflection however shows the problem.
How to fix this?
maybe turn up glossy bounces? disable any auto clipping or filters, max and min bounces should be greater then the highest bounce, etc.
i personally like:
- min and max at 8
- diffuse at 4 for indoors
- glossy 4 (maybe 8 for crazy)
- 8 transmission.
Thanks for the idea. I just tried many different combinations of that with no change at all.
This one is curious. I guess I just use a better model.
Sharing a towel and the mirror might make someone have a look at it.
Good idea. That had not occurred to me.
But when preparing the stripped down file I discovered an area light is causing this.
When turned on (even slightly) I get the problem. When off the reflection renders as expected.
This looks like a bug to me. I’ve got a deadline so I’m out of here.
Thanks to you and @Daedalus_MDW for trying.
