Hello! I have got problem with Redshift applying motion blur on cached cloth animation, any thoughts?

#1

Hello, i have cached cloth animation of waving flag in the wind, so i want to render it out within Redshift using motion blur, but whatever i do nothing seems working… The motion blur does not appear. What have i do first?

(I have the motion blur enabled in Redshift render settings + assigned RS Tag on Camera and also i have the deformation blur option enabled) So i have no clue what to do. I want to avoid to bake animation if i can…

Thank you guys in advance!

And another problem is about shadows casted by infinite light, it does bad shadows, see the triangles of light in that shadow…

Hm, maybe the motion is too slow for your MotionBlur-Settings?
I attached a scene with visible xpCloth-Motionblur, so you can compare your settings.
Also remember, RS Motionblur is only visible in a full render, not in IPR.

Regarding the light I have no idea. Maybe it helps to add more geometric detail? (RS-Object Tag -> Enable Tesselation)

Thank you for your quick reply keppn! So i am lucky i have bought X-Particles but have not time to learn yet :slight_smile: So i opened and it works, so i tried to apply your render settings and something happens, after i added more deformation steps the motion blur is there finally! :slight_smile:

To speak about the shadow, So i tried to apply the RS Tag and enabled tessalation, it fixed the problem little bit but not completelly. I have to play arround a bit more :slight_smile: But thank you!

I have another question, i want to achieve to let the light go through the cloth texture, do i have to use sub surface scattering? Or is there another option? Thank you

Yeah, Subsurface Scattering will brighten the flag.

If you want little visible God Rays poking through the flag, you need:

  • Holes in the flag (e.g. an Alpha map)
  • RS Environment
  • RS Light wich contributes to the Volume of the Environment

About your problem with shadows, did you up the light shadow samples? don’t be afraid to crank it up 1024 or double.
For the light through the cloth, being so thin, why not use the back-lighting/translucency?

Ah, I enabled “Automatic Sampling” under the Tab “Experimental Options” and never looked back. For me, it works much better than sprinkling samples myself :slight_smile:
