Octane not working with Unity UI?

[lineofsight]

Hi,

why doesn't Octane render the native Unity UI? I'm working with Unity 2017.3.1p1 and Octane 1.1.1.1324. Am I missing something?

Thanks a lot!

I can confirm. (do I need to specify a license type for free single GPU use?)
I just tried with Unity 2018.2.8f1 AND 2018.3.0b7 with
Octane 1.1.1.1341
I get 2 Unity console errors:

Failed to locate cudnn64_7.dll

Octane.DynamicLibrary:CheckPath()
Octane.DynamicLibrary:Load()
Octane.PluginDllLoader:LoadLibraries()

AND

Fred, please open a new thread. Your Problem has nothing to do with mine. I'm talking about Octane not rendering the Unity UI (i.e. Canvases, Buttons, Sliders, Panels etc.)

That being said, your sharing violation error most likely results from you having two Unity instances (or another second process) open and both are trying to access the same file.
IIRC, restarting Unity after the sharing violation has been taken care of should also fix the missing DLL error.

The native Unity's UI is quite slow when drawing it from script (which we do for things like the Render Target controls), and converting the entire Octane UI (especially with all the messaging back and forth between Octane and Unity) would be too much of a performance impact.
