OTOY Forums

So I was working on a scene that included several 8K tree textures. I brought in all the textures, and placed them on the objects without issue. Everything rendered great with no errors. However, when I tried to bring in a new object with 8K textures, Octane might work for a bit, but when I try to adjust something it crashes. Sometimes it might just fail to load to begin with. I've dealt with scenes with far more objects and textures before without issue, but it seems this scene has arbitrarily decided not to work when I try bring in another texture. To be clear, this is an issue with the textures, not the objects themselves. They are all 8K jpegs with displacement. The issue still pops up even with other textures that are smaller.

Error Log:

Another error i get when its not the former:

I'm using Titan XP on Cinema 4D with an EGPU enclosure. And all drivers are up to date. Is there any way to fix this issue?

Are you using Windows 7?

No, I'm using Mac OS High Serria

Update: I've found the issue (certain textures in my scene are causing the crashes). I've made a second post: viewtopic.php?f=9&t=69441

I'm having a similar error, but on multiple scenes in c4d using the c4d plugin.
