First - Thanks for all the info - I'll download the apprentice version, hook up to the houdini forum, and watch the course about the boat/ocean...
Second - I didn't explain myself correctly - I have 44 threads in total on my 2 machines (after hyper-thread) - An old i7 (6 cores, 12 threads) and a new amd threadtripper (16 cores, 32 threads). But even if I run the simulation on the 32 threads machine I think it will be enough for 150 frames - It can work for many hours without compromising with my daily work...
I hope I'll be able to extract the displacement map from houdini to vray for the ocean water - I think it will be much easier and better to render everything in vray
I'll update here about my progress
Peace,
Kobi
