Hi ,
I have an osl shader / projection that was working fine on the last 3 betas of octane for blender 4.5.
When I loaded the scene and gone to world node shaders for some edit it lead to crash.
tried a few things and then I recreate the environment in a temporary scene.
when i finished and wanted to add my projection OSL that flatens ground, like a half dome projection
when i connected and compiled the shader blender crashed again.

I attached some things like osl shader and the picture that show the crash as i coonected uv projection out to projection in.

If you guys need anything else from me , please ask.

Ok, simple way to reproduce...
Add the osl I attach here,
In shader/world node an OSL Projection node as external,load it and hit compile.

Blender 5.0 and 5.01 with octane_blender_addon-31.2-beta and octane_blender_addon-31.2-beta(6).
Not tested with one you posted today yet

Thanks

OSL related nodes need several fixes, due to the changes in Blender 5.0 APIs.
