Reply To: On the floor material everything looks fine until I connect the bump node into the normal socket on the Principled BSDF, and it goes pink, why?

Hey @az93 , I can’t see anything wrong with your nodes. The pink would normally indicate a missing texture.

I can see you have Eevee selected in the material output node, make sure you also have Eevee selected in the render properties. I normally leave the material output at the default , All.

Double check your nodes, make sure you don’t have duplicates, one on top of the other.

Try saving your work, close Blender, and then open up the file again in Blender. It may be a hardware issue, memory probably if it is. Saving, closing and reopening Blender will clear out anything being held in the memory.
