sometimes Octane slowly crashes?

Thu Oct 02, 2014 1:01 pm

I've started to notice that when working on some heavier scenes (8000px renders with displacement maps and glass) that Octane will run slower and slower and slower each time I restart a render or switch inbetween scenes, until it quits working all together. when this happens, i just restart maya and everything works fine again.

example: I just had a scene that was rendering around 3mb/s and after a few material adjustments (minor adjustmenst that should cause now slowdown) and render refreshes the scene was going at 700kb/s. I restarted maya and everything was back at 3mb/s.

This type of cycle has been happening pretty reguarly. any clue what's up with this? Is VRAM not clearing out between renders or something?

Could you share the scene where it is reproduceable?..

I don't know if it's in any way related, but I've been noticing something similar in Cinema 4D. If it's a big heavy scene that I have been working at for a long time and maybe tried out a lot of materials, it's not enough that I restart Cinema. I need to copy my entire scene and paste it into a new or Octane will crawl to almost a complete standstill. Not the LW but the final render.

Unfortunately I don't have a scene where it's 100% reproducable. Some days it happens but some days it doesn't. is there any type of software you could recommend so I can monitor what is going on in my GPUs? When I notice the scene start to crawl I can see if anything out of the ordinary is happening in the cards and maybe give you a better idea of the issue.

I downloaded GPU-z today to check out what was going on. Nothing out of the ordinary. Looks like it took a little while after I started a render until the 2nd CPU engaged but nothing too crazy. I'll keep checking this when i start to see real problems.

On another note, the 2.1 plugin update that just came out said it fixed a bug with the processor not working. I'm assuming by "processor" it means CPU and not GPU, therefore it's unrelated to this issue?
