Problems with RenderPipeline

Hi,

I tried to change the skybox in RenderPipeline by adding a new skybox.jpg and converting it to txo.pz but that did not change anything and the sky kept it’s original colour. Additionaly I tried to edit the skybox.bam in blender and give it a colour there. No effects.
My other question is whether I can make a custom yaml file which disables the debugger, motion blur and fog and load it?

Best
