Hey everyone, I am running Houdini apprentice 12.1.185, and I am having trouble rendering. It was working fine two builds ago, but ever since i upgraded to 12.1.125, Mantra hasn't been working.
Basically I click render in the mantra node, and it takes about 10 seconds, and then I get the error: Command Exit Code 1, and then mplay loads up, but it just shows a black rectangle, about 300x 50 (ish?). I made sure I have my camera, my lgihts, and the right settings for the camera (because I have the apprentice, so limited resolution).
Also, it doesn't work when I click the View: Mantra button at the bottom left of the viewport editor.
Also, other random info: my licenses are all running and working properly, i've had this problem with both Houdini and Houdini FX, and the Render view tab also doesn't work and just loads up mplay when i click render.
I think I've covered almost everything, thanks in advance for the help!

**Edit- It also says : “Mantra: Could not open imager”
