I'm looking forward to when the  SSS/Trans starts working for the thinner mats as in leaves!  SSS hasn't caused a crash on me yet - but renders very slow - EON has said this is a known issue.

Displacement cause me great troubles as well, I filed a tech ticket.

PUt in terrain - set displacement - render(final mode) - stop render - tweak displacement - re-render at this point Vue does a hard crash with error of proengine.eon or MSVCR80.dll. I have replicated this about 20+ times LOL.

EON is looking at it :)
