"Performance loss: dynamic memory limit too low"

Folks,
when rendering large formats at reasonable high quality for printing, I’ve encountered following problem:

Render progress window says, “Performance loss: dynamic memory limit too low”.

It happens in areas of complex geometry (--> displacement map) when computing the prepass, which is just one pass due to distributed rendering.
Calculation comes to a halt and doesn’t seem to progress any further.

Which variables should I tweak in order to get it running properly? (using DMC and IM)

Thanks guys!

Cheers,
Matt

Re: “Performance loss: dynamic memory limit too low”

Under the “system” rollout we have an option called “Dynamic Memory Limit” this option basically save memory for the dynamic geometry. Displacement is considerate a dynamic geometry so maybe you have to increase this value to save more memory for the displacement.

Well, it just says Mem limit (I’m using 1.05.29).
But when I increase the value, it seems to work :slight_smile:

Thanks a lot!
