Having an issue with LightMix where I often have to turn one of checkboxes off and on for the frame buffer to recognise that I'm on the LightMix element.
This happens when rendering a region, or sometimes just restarting IR.
Hard to explain, but I've got the lightmix element selected in the frame buffer but it doesn't show the results of lightmix until I tinker with something. As if it defaults back to Beauty if the render is restarted or a region is rendered.
