Hello,
i find out problem when i would to set SUN - custom orientation and i would to experiment due interactive render and change orientatiton. Vray will freeze each time, i have RTX 3090 and i try it in RTX and CUDA mode, same problem, instantly freeze. Only if i use CPU, i can change orientation and see it realtime.
After freeze and restart sketchup is all of my section planes doubled, each one make copy of themselfs.
Second question is about Light cache in RTX mode, this took sooooooooo much time to load even if LC is only 800 … can you do please something with it ? CPU LC is calculated very fast.. but gpu, even with this rtx3090 card is too slow.
@zazracnedieta Hey! thanks for the report
About Light cache, how much time does it take to calculate in your case? And does this happen with all scenes?
In my case even at 3000 Subdivs it renders in 15 to 20 seconds for all scenes, and is much faster than CPU
For interior scenes you actually need around 3000 LC Subdivs, which can speed up rendering a lot
About the first issue, when you talk about a freeze? is this a crash or what happens?
Please attach a screenshot and a simple test scene, the SketchUp team will follow along with you
Best,
Muhammed
Hello, here is for example a random scene: https://drive.google.com/file/d/1GlCQ\_BdVPxoQGSssTA\_EmbJe8N-LxCOK/view?usp=sharing
I try render in this modes:
cpu - lc 3000 - 35 sec
cpu - lc 1000 - 5 sec
cuda cpu+gpu - lc 3000 - 28 sec
cuda cpu+gpu - lc 1000 - 17 sec
rtx - lc 3000 -45 sec
rtx - lc 1000 -28 sec
about freezes while interactive render: when i would to try set custom orientation in projects /in all projects, not just this/ when i try it with RTX mode, when i pick custom orientation and new PRG sun, and start interactive render, when i change some angle or horizontal orientation, sketchup and vray freeze, nothing is changed and i must restart sketchup. Same problem with CUDA. When i try it with only CPU, everything seems ok, no problems.. even if i choose NVIDIA denoiser.
my pc spec: TR1950x, 64gb ram, RTX 3090 24gb..
update: couple of times i get this error:

Thank you!
About GPU LC, we identified the issue and looking into it now.
About the freeze, I will type to my SketchUp colleagues to take a look
Best,
Muhammed
good to hear it Muhammed, thank you 
hello Konstantin,
maybe is best solution to someday using teamviewer, so you can see my problems on own eyes, an vray behavior
Iam available daily between 10-20 CET
you or your colegue can wright my a email from my account so we can settle this
Hello,
Please excuse me for the delay!
I have contacted you via email so we can arrange a remote session. Support ticket #20509
Let me know if you have received it.
@slavcho.brusev
1. as we disqus in private emails to do some teamviewer session, i today try one thing and it seems like it helps
i find solution, that i need to delete /for now i just move file out and keep it :)/ FrameBufferState.fbs from directory C:\Users\User\AppData\Roaming\Chaos Group\V-Ray for SketchUp
I dont know if its useful, but it seems, like this solution helps many other people with freezing during RT render
2. But i still have second problem and that is, that if i make section planes and close project, after opening it i have all sections planes doubled
EDIT: ooh, after a while, i get same problem with RT :-/ so i will contact you next week.
To give a summary from the remote session:
i find out problem when i would to set SUN - custom orientation and i would to experiment due interactive render and change orientatiton. Vray will freeze each time, i have RTX 3090 and i try it in RTX and CUDA mode, same problem, instantly freeze. Only if i use CPU, i can change orientation and see it realtime.
Basically, this was resolved by resetting the render settings from this button in the Asset Editor 
And manually readjusting to RTX engine and high resolution.
