Render Issue on first frames

[skoeth]

Hi,

lately i get strange "watermarks" when rendering stuff with image sequences in its materials.
So always the first frame gets weird artefacts like known by gpu issues.

I attached two images to show what it looks like.

You can see my specs in my signature, any suggestions what could be the problem?
I think 2 days ago it worked just fine, didn't update any drivers since then.


thank you and have a nice day!

version?

[skoeth]

version?

2.23.1, both standalone and plugin.

Are you using netrender?

[skoeth]

Yes, i'm using netrender indeed.
Anything wrong with it?

This has happenedto me a couple of times using net render on the newest version. It only happens on the first couple of frames.

Some have reported this problem in the past, but I still don't know what the issue is, because I can't reproduce it here at all. What is the GPU configuration on your master and your slaves? Which OS are you using on the master and the slaves? Did you render HDR images or LDR?

Is there a way for me to somehow reproduce this issue? I really want to fix this problem, but don't have an idea where the bug is...

here comes my configuration:
master:
OSX 10.10.3 with a GTX 970 +external TitanZ and GTX 780

slave:
OSX 10.10.3 with a GTX 780ti + external 2x GTX 780ti

the externals are connected via the amfeltec gpu cluster - one for each machine.
running octane 2.23.1 both, standalone and plugin.
No HDR.

I think it happens when using image sequences, but i cant reproduce it as well, for today its just working without knowingly changing anything.
my first thought was image sequence + netrender.
