Thanks a bunch !

What he said.

If I have an object sequence in my scene is it possible to render without reloading the entire scene ?

I think I have found and isolated a bug.

Sphere light + AI Light crashes nodes.

Sample scene attached.

It's a regular out of memory -> failed to allocate device array error.

Funny thing is that it renders for 20 seconds and then throws out this error.

It doesn't matter how many 3090s are in the system, RAM usage is the same for 1 or 2 3090s, I've checked.
And they consumed only 18GB of RAM, started rendering and after 20 seconds, out of memory.

(this happens only in the node, in master computer 3090s render fine)

Two 3090s in the node throw out of memory errors.
If only one of them is active there is no out of memory error.
Node has 32GB of RAM and it doesn't waste all of it when two are active.

Here is the scene. I hope you can figure out what am I doing wrong.

I have managed to get hair motion blur working but as I increase motion blur amount from 0 - 0.5 the motion blur is visible on the hairs but almost half of the hair disappears ( underlaying object becomes visible instead).

Does current LW version have some boolean rendering capabilities ?
