MtoA: RTX 2080 Super won't even render a lambert sphere. Constantly getting "Unknown" OptiX errors => CUDA driver CuEventSynchronize errors => returning either (700), (716), or (718)

Tried to sum it up in the title. Not sure if it's enough

Maya version 2022.1

MtoA version 4.2.3 - c0f6fdce (RB-4.2.3) Jun 7 2021

Arnold Core 6.2.1.1

Current NVIDIA driver is 27.21.14.6089

Here is the full log:

00:03:18 2259MB ERROR | [gpu] an error happened during rendering. OptiX error is: Unknown error (Details: Function "_rtContextLaunch2D" caught exception: Encountered a CUDA error: cudaDriver().CuEventSynchronize( m_event ) returned (716): Misaligned address, file: <internal>, line: 0)

GPU 0 had 7549MB free before rendering started and 6660MB free when crash occurred

Do you mean the Maya script editor log, the text from the output window, or the text from the Arnold log window?

I provided the text from the Arnold log in my previous message. But I will also attach a .txt file that includes everything from the Maya Output window.

Thank you

I just see the ERROR in the original message.

The Arnold log from the Output Window shows that you have an older NVidia driver.

For MtoA 4.2.3
