Suddenly I only have a "Headlight" and a "Normal light" instead of the default "Work lights" and "Scene lights" in Houdini 21.0.7. Also most of the options are gone , only the default properties are visible.

I still have one copy of Houdini open with the proper work light options , but when I open a new Houdini window , the work lights are gone.



Does anyone know how to fix this ?

I guess you switched to Opengl. These Options are only available to vulkan.

Ah , that's the trick.

I guess somehow Houdini suddenly decided to switch back to OpenGL.

Thanks !
