Prolem with the pain effects

Seeing as we were going to have a fish and in our scene we wanted to make it as real looking as possible, Ashlee want ahead and looked at verious different pain effects which was useful when creating the under water like environment. When Ash brought in the next day i was very pleased with the results and how it fitted in with the fish tank plus ash placed the wind dynamics with one of the bushy looking thing which gave soft smooth movment like what you would see in an actual aquarium. But with all good things a problem always lurks round the corner, the actual file of the pain effect came a total of 200mg which kind of got me worried. I renderd about 50 frames on maya software which took about 2 mins which was ok, but right from the get go i knew we were going for photorealsitic look and inorder for us to achieve this we were going to have use maya mental ray. I went and had a go at rendering the scene under MR and the result came back quite badly, the first problem that arised was that rendering one frame took roughly 10 min and the second problem was that when rendering a single frame the screen was prompted with the famous c++ error.

I didnt want t give up hope just yet so i went home and tried to render a single frame hoping for a better result. The result came up even worse with rendering one frame took more then 30 mins, the reason for this was becuase i had placed photorealistic lighting settings such as GI and FG and not to mention a HDRI. And the worst part about it was i hadnt even imported the fluid from realflow which would increase the rendering time 10 folds. The only decision i had to come to was to not have the paint effects, i notified Ash about is but i would rather talk to him in person.
