Problem

Description:

Hello

V: 1.0.9.8686 and earlier

I have a Character with full Hair, I make a tesk rendering (only arm visible) with motion blur check on and with enable deformation blur check on, and the time of rendering is insine

Motion Blur with enable deformation blur: 2h50

Motion Blur without deformation blur: 2min

And my character is not moving, he is in T-stand so imagine with animation....

So I try with motion vector instead and the scn seams crashing after few hour of rendering

 

See images

tks a lot for you help

Difficult to reproduce, because it work with a simple sphere

Looks like something we'll have to ask Redshift guys. I just sent Nicolas an email, will update you once I get something back.

Hello Marsel,

Nicolas wrote me that now the last straight line is in your side?
Do you feel comfortable that you will found a solution? I need to think a plan B.

We tried to not calculate motion blur by rendering a motion vector pass, but It took so much time to translate that we gave up.

Do you have an estimate for the fix? pls

Tks again for you help.
