Since the hardware is completely different, I'm guessing this might be caused by some sort of setting / script that's carried over from my previous Blender settings. No keys / settings modified.Ĭurrent machine is 3950x, 64gb ram, rtx3090, windows 10 I've done a factory reset for Blender Octane and only added the Octane plugin, still the same issue. I completely replaced my PC recently, this was happening on the old machine, it's happening on the new one as well. Latest NVIDIA drivers, just did a clean install of Windows. Currently running the latest version, latest Prime as well - no change. I've tried updating to the past few versions of the plugin - it happened with all of them. Waiting for image will display and each next step will take a very, very long time. If I try to do an F12 render - it will be the same. The Blender viewport will still be frozen. If I open the Octane Viewport from the menu, after waiting for 10 minutes or so for a cube to load in the Blender viewport, the Octane viewport will display the scene correctly and update as normal. It seems like it's working, just incredibly slowly and each step taking far longer than it should.

Or I could have a scene full of geometry, it really doesn't make a difference. I can just have a cube and go to the render viewport and it will freeze. This issue happens no matter what the scene is. If I leave it for 5 minutes, it might move on to 'Render-target evaluation on server' and update the image, but it takes minutes for each minor refresh and it's completely unusable. It displays the message 'Waiting for image.' and it just hangs there, nothing happening. It was working just fine, then it started freezing when I enter the Rendered mode in the viewport. I've been having an issue with the Octane Blender plugin for several months.
