Title: Corona hair flickering in animation - Object with pointdeformation
Post by: Core2000 on 2019-04-10, 16:57:16

Hi,

we have problems with corona Hair rendering on geometry with point animation. Corona hair is flickering in animation.
When we use Cinema hair renderer, there is no flickering. When we generate Hair polygons and render with Corona there is no flickering, but we cant generate 500000 Hairs.

See the sample C4D files and mp4 files.

We need a fast fixing for our deadline.

Cheers
Alex

Do you have a fast solution for this problem? We need to start our rendering. If there is no fix we have to change to a different renderer. I hope it will work in corona.

We've probably found what was causing the issue, so it should be fixed in the next daily build.

Hi Serghei,
previously it was only fixed in daily builds of version 4. Public version of v4 was released few hours ago and it should be working there (you can download it from our download page (https://corona-renderer.com/download)).
