Hi guys,

Really hoping someone here has some ideas regarding the problem I'm facing.

I have a Solaris setup with some imported geometry, 3 lights, a material library with the most basic MTLX Standard Surface, an assignmaterial node, and a Karma node at the end.

I make two simple keyframes with the canera, select Render Frame Range (in my case 1-72) and hit Render to MPlay.

I am faced with the following error on the Karma Render node:

Warning
Found layers that share a common save path: layer created by '/stage/materiallibrary1' saving to './stage/materiallibrary1.usd'.
Saving to './stage/materiallibrary1_duplicate3.usd' instead.
Warning
Failed to complete render: exit code -1073740791
Use a Log Viewer with External Render Processes enabled for more information.

The minute I disabled either the materiallibrary or assignmaterial, the scene renders. I cannot for the life of me figure out what on earth is going on!

Any help or pointers would be hugely appreciated!

thanks

Its just a guess but I think the way you merge the lights leads to the duplicate material primitives.
Try to connect after another, via a sublayer as described here (https://www.sidefx.com/docs/houdini/solaris/tutorial-lighting-3.html)
or just have an input connection to the first light. This might also fix the error during rendering.

Cheers Dome

did you figure it out?
