caustic problem

[Moataz]

Hi guys
when i choose PPM as render engine that make the caustic vcery good in interactive rendering ..
but when i click to render the view then 3dsmax shutdown
is there any other way to make the caustic same effect .. or any help with the shutdown problem !!

Those render engines are experimental, so basically they are only considered workarounds right now, and are very limited. See: https://coronarenderer.freshdesk.com/support/solutions/articles/12000043584
We will soon release a build with a brand new caustics solver.
