Good to know!
I have discovered an interesting thing about Drivers. Normally they don’t seem to update values in the custom node tree. BUT if you link any value from the node tree as a driver to an external property it suddenly starts working?!
External properties linked into the tree still don’t see to work though.
- Create tree
- Create a custom property on your scenes World, it can be anything
- Right click on any numeric value on a node and ‘Copy as Driver’
- Right click on your Worlds custom property and ‘Paste as Driver’
- Now any drivers you create within the node tree will work! Link all your Samples and X/Y inputs with drivers.
I do have one more small update to fix the subsurface pass in old node trees, make the preference categories collapsible, add the ‘Edge’ mode to ‘Cavity’ pass and include the tile size change for emit passes (in my tests this didn’t give as big a performance boost as in the video, but it was a little bit faster so seems worth). But I would like to wait and see if anyone can find more bugs before I drop it…
I’m also going to report the driver thing and see if someone at Blender will fix it.
