I’ve got this far with creating a scene for the sub. Been using the ocean modifier for the sea, which I’m fairly pleased with, and dynamic paint to create a wake if front of the boat, which is a bit of a hit and miss affair at the moment. I have been using a scaled up cylinder as a stand in for the sub, but if I crank the resolution up to 20 on the ocean modifier and then try to animate the passage of the cylinder through the water my computer slows to a crawl. So that’s not great for editing purposes.
I would like to make the flow of the water across the sub’s body more dramatic looking, foam and splashes of water rising up, and also add an effect to the rear of the sub to indicate that the propellers are churning the water. I’ve no real idea how to achieve either of these effects so if anyone has any ideas or knows of tutorials that might help I would be glad for the info.
I used a HDR image for the background, I got it from this site. http://www.hdrlabs.com/sibl/archive.html
