Render Fails after Scene Load

Here is a copy of the log file, and a screencap of the CUDA state:

The answer is in the log file. Your scene takes too much memory. You can try to reduce image texture size, and make sure textures which don't contain colours are loaded using greyscale image nodes rather than RGB image nodes.

Just discovered something interesting about the problem. If I do NOT connect either a texture environment or daylight, and have just the lights in my studio setup, the problem happens. If I then also connect up either texture environment or daylight, the problem goes away.

I am confused, though. The memory bar shows I have plenty of memory. And why would the problem go away simply by going inside a group and popping back out again...The size of the texture memory space has not changed.

[roeland]

That's possible. The closer you get to using all memory, the more probability one of the memory allocations fail. This can happen a bit randomly, there is no way to avoid that. And if there is not enough memory Octane will stop uploading at some point, so the memory usage shown may be only half your scene.

Well, once I get it to recover, it does seem to render everything when I let it run. I have not seen any missing textures, or visible glitches. Even when the failure occurs and 95% of the bar is filled.

Problem seems fixed in v1.28.
