The PxrOSL Pattern node is a useful way to create and prototype OSL patterns from inside Maya.
| Info |
|---|
We only support OSL patterns (textures for shading) and not closures (materials). |
When you first open the node you'll see the representation above. If you expand the Source Code rollout you'll find a handy example built-in to the node.
You can see the source path under Compile and Reload buttons.
Compile - Compile the current code to a .oso file for rendering (we needs this stel from the .osl form)
Reload Source File - External edits to the file can be loaded from the saved/updated .osl file
The plus and minus icons are to expand and shrink the editor area.
The Parameters rollout will populate given a correct .args file. You can find examples of this by looking at the PxrLayer node.
