Retrorender
I keep getting an error when I try to install RetroRender as an addon.
RetroRender is not an addon. You must append the nodegroups from the downloaded blender file into your blender project and add the nodegroup to your blender compositor nodetree.
I can’t see RetroRender’s effects in the viewport.
Make sure you have the compositor activated in the viewport (either Camera or Always) and have the RetroRender nodegroup plugged in to you compositor node tree.
