Delay and problem with IPR

[spigolo]

Hello
i m working with Lw 2019.03 and lates Octane 4.04 plugin but Im having stange issues with the IPR which I didn't noticed somedays ago.
I have ot say that yesterday I have reinstalled windows 10 and updated lightwave and the Octane plugin, (previously everything was fine)

The problem I have is that when I open the IPR it stays often on hold for some seconds without any notice about loadinggeometry etc etc.
Then after a while it shows just the environment (no objects loaded).
If then I press reload everything works..

The scene Im working is full of instances and lot of geometry but In the past I have made scenes heavier than this without any issue like this, maybe it took a bit for Ipr to load everything but at the end it was showing everything..
now I have to do this in 2 step.first load nothing than reload...

What could be the cause?

Kind regards

Hi,

Sorry, I'm not sure what could be the problem. I can understand that the scene extraction could be huge if the scene is complex with a lot of instances, especially if the motion blur is enabled, but in the end, the IPR rendering should be fine. Could you send me a scene with this problem to try to reproduce this problem here?

Thanks,

Ok I will if you send me again your email.
I also have a new issue that I have never seen before...
Its an old scene that worked fine before installing 4.04 (before it was 4) and a fresh install of windows 10...

Ok enabling out of core fixed this latest issue...

I've been trying to reproduce your first problem here, but without luck so far. Here the IPR always load and render the scene without problems. I wonder if the problem could be related to the drivers, but it is hard to say. Here I'm working with the .419 drivers without problems.

Thanks,
