[C4D] Bug Reporting / Interactive Renderer - Shading error when multiplying images with a color

« on: 2022-11-11, 12:11:43 »

Hi,

Ive found that the materials (their reflection mostly) in the IPR turn yellow when lights are moved. This seems to be a bug when multiplying the Texture of the background with a color.

The workaround would be to use a Corona color mix - which works but thats just one more uneccessery step.

[C4D] I need help! / AMD 3990X massive slowdowns

« on: 2022-09-16, 10:55:29 »

Hi there,

We configured a Workstation with a AMD Threadripper 3990X hoping it would be a blast to work with in C4d + Corona which it is if you do rendering only. But as soon as you use the Interactive Renderer do this the whole System becomes unusable - you cant even move explorer windows without huge lags. So every speed advantage is completely lost since you cant work in your scene while IR is running.
Also Material editing seems to be extremly slow due to (I guess) rendering the preview for the material manager before updating the Viewport.

# threads override seems to work if you use a very small count like 12 - which then is too slow in rendering. If you use anything high the system breaks down again.

Has anyone any ideas or had a similar experience and knows a fix? Please let me know

Faithfully,
                 Marc
