Phoenix Liquid and Irradiance Map Animation Mode

[vandy]

I have an interior of deer with blood flowing around organs. I set the GI on Brute Force for both Primary and Secondary, and it's taking around 8 hours per frame. When I change primary to Irradiance, the time goes down to a little over an hour, much better; but can I save more time (and lock-down GI) by creating a time-sparse cache when there's animation involved? I don't find much information on V-Ray settings and using Phoenix objects like liquid. Does anyone know any good links? What are the rules/guidelines for setting up V-Ray with Phoenix? Do you never create a cache when there's animation?

the liquid is just a mesh, it should be fast like any other mesh. i hope you are using mesh mode, not implicit surface right?
the slow phoenix objects are the smoke and the foam, but you didn't mention to have any of them.

You are fast Ivo! Yes it's render as mesh and no smoke or foam. So I can just create a time-sparse cache with multi-frame set? Then after, read from it and have brute force in secondary? Also, is there any documentation on the V-Ray settings for using Phoenix? Thx.

Like Ivo pointed out you could use the same Vray approaches to render Phoenix liquids.
Currently we don't have any docs about Vray settings for rendering Phoenix simulations but if you have any specific questions you could open a new thread into our forums or contact us at support@chaosgroup.com and we will do our best in order to help you out.
