Updating geometry/collecting nodes are killing 3ds max

[leesungwoo]

Hi, everyone. I'm trying to render some complex scene and I did some test in these days.

The main problem is Octane render frame stuck in Updating geometry/collecting nodes/building render targets
There are many decimated debris and objects in my scene, the entire scene has 18,000,000 polygons. I was thought the VRAM causes this problem, but after I picked 1080ti (GTX970 before), this issue still there.

GPU and CPU were just working like casual when the render frame stuck.
These are some information in my scenes.

0.polygon count: 18,000,000
1.9GB VRAM
2.16GB RAM
3.Foliage are using scattering system
4.Instance objects(some of them are proxies)

So, I'm confusing what causes the problem? Am I did some wrong manipulation or I don't have enough memories?

I'm a real-time environment artist, I know the optimization is important maybe that is the key. But one of the reasons that I choose offline rendering in this time is I don't want to spend too much time on Topology, baking, etc.

Thanks for the reply, I have tried newest version. It actually runs faster than before but the problem still exists. Perhaps I need to add more RAM on my PC.

CPU memory Turn on (4GB)

Hi leesungwoo,
It's hard to say about your issue with this little informations.
How much ram about your computer?
Could you share screenshots with your kernel setup and your scene (private message if you want)?

From my experience use itoo forest to the max for fast loads. As far as ram if you use 6gb of vram you need at least 10 gb of ram. It is better to just get 16. 8 is not enough and it will crash pc for a brief period and then it will stop rendering.
