Hello

I am looking for solutions for my project.
Octane is failed rendering a scene with no textures but zillions of geometry. ( 10 buildings destroyed )

All my dynamic simulations are cached in a single one.

I have a RTX2080 TI with 11 gig memory.

The rendering is starting and take very long time to load the scene in gpu then Houdini crash after about 40 mins

I really don't know how i can optimize the scene more than what i did..

Does packing can help? or activating out of core (64 gig RAM on my system )

Thanks

Here is the visual..

Enabling the out-of-core feature is going to help for sure, but you should also be aware that there are limits about the amount of geometry that a single OBJ node can handle.

If you are working with OBJ nodes including several millions of polygons you should think about breaking it into several additional OBJ nodes, importing a set of data into each one. This has two advantages: avoid reaching the Octane limits in the number of data that a single OBJ node can handle, and improve the scene extraction time due to the multi-thread scene extraction feature, which can split the expansion of several OBJ nodes among all your CPU cores.

Hope it helps,

Thanks Juanjgon!

I will try that

Please tell me the limit per obj node?

I will give you feedback!

Best

It is hard to say because it depends on the number of UV maps, user attributes, etc. but I'm sure that a single OBJ node with let's say 50 MPolygons could fail, and the scene extraction time can be very slow.

Thanks again Juanjo!

Now i can render with the IPR!

I will now try to render all the sequence.

Best!

Yay!!!

Thanks you so much!

Great! I'm glad your scene can be rendered now.

Thanks,

I've been able to render all the frames last night
