Is it possible to enable visualization of Cycles shader nodes in the node editor when using another render engine? I tried adding
layout.prop(context.space_data "tree_type")
to the header but that only shows compositing and texture node editors.
IIRC the poll method for the cycles nodetree has a check on the active render engine (scene.renderer.engine or something like that, dunno, totally guessing?) which causes it to return False if cycles isn’t the active engine.
as i remember you cannot see cycles nodes while in blender mode!
you have to select one renderer first
then see it’s own nodes set up!
happy cycles
What about a refresh button that would switch to cycles transparently, render a 64x64 pixels of a sphere with cycles and save it as png/jpg to be displayed in the node editor ?
I’m a noob with the python API, so I’ve no idea if it’s possible, but I think it should be possible.
well you could use composite to mix different rendered images!
and you would see the 2 but not one by one!
or another trick might be to render in a specific slot then
do another render in slot 1 then you can switch between the 2!
happy cycles
