This is actually something i've been having issues with for a long time but only now is it becoming a real problem. I'm using the latest version of Octane 2 (uninstalled 3 for the moment)
The problem I have is when rendering out using the layer/passes system. On final compositing, there seems to be a small pixel wide gap between the beauty render and the shadow pass. When you comp it all together this results in an almost halo like outline around the beauty pass. Anyone know of a way around this because it's hard to fix in post, if you scale the shadow layer up or move it then you get an outline appearing elsewhere.
Normally when I render out shadow pass with other renderers they do not 'cut out' the shape of the shadow casting object and so do not leave any margin for error.
Is there any way we could have an option for a shadow pass that includes all the shadows cast (not one which cuts out/outlines the shadow casting object?) Shadow layers generally sit behind everything in the stack so it doesn't need to have anythig sut out of it.
Anyhow I don't know if this is an issue with the 3dsmax plugin or standalone, but it is very problematic for me.
