Render Problems

Render Problems

Hi all,

i have some problems with rendering animations. Sometimes there are some spots rendered „from nothing“. I have tried several settings in the camera settings and the radiosity tag – but they still appear – even when the object is not moving … Rendered file is here: https://www.dropbox.com/s/7kbjogml1hnyb3h/Innenteil-Drehen.mov?dl=0
Here you can see the spots above the rotating elements

Any idea? Thanks in advance for any suggestion …

Hi and Welcome!
I don´t think you´re expecting a scripting solution as we´re in the scripting area of this forum. ;)

These are artifacts caused by the irradiance cache of the radiosity tag.
1. Try to to decrease the value for the Rmin setting
2. Take a lower Error value which will increase render time - don´t go under 0,05 as it will disable the I-cache and brut force path tracing takes place.
3. Enable Detail detection

Let´s see if this helps already - as I guess your´s model is small.

Cheers
Frank
