I'm trying to build a very simple LOPs/Karma render test.
In the /stage context, I added a sopcreate LOP.
Inside that I added a cube SOP, following by a Normals SOP.
At the /stage context, I added a light LOP.
I merge these with a merge LOP, set to flatten layers.
Downstream of this I added a camera LOP called camera1.
Then to this I add a Karma LOP.
In the Karma LOP, I set the Camera field to /camera1
When I switch the scene view from openGL to karma, I see the cube from the /camera1 view.
I press the Save to Disk button in the Karma LOP, with images/Output Picture set to the default ip.
With rendering/statistics/show alfred progress enabled, I see in the terminal that the render completes.
But the auto-launched image viewer shows zero in RGB and A.
What am I missing?
It would be helpful if someone could share a Karma “hello world” example.
Thanks

With everyone's help, the new Solaris documentation, and tutorials shared in this thread, I was able to:
- Sim a squab falling onto a surface using vellum tetrahedral softbody to make it come to rest naturally.
- Procedurally model and create materials for mashed potatoes and baked potatoes
- Platter is procedurally modeled.
- Import the above into a /stage context
- Apply materials in LOPS
- Add a key and dome light in LOPS
- Render Karma to disk
