Ocean and wake tutorial

[BAKMS]

This is a HARD and Difficult one....
Please help.

I have noticed Digiarist, Songbird, and Deetz; plus many others have created some outstanding renders.

I am requesting to create an Ocean and Wake for a ship that is very realistic.
I am using Max 9 and hoping to stay in max.

I have created the Ocean using Dreamscape 2.5c, which I really like; due to the Ocean grows to the horizon and builds the sky also.

The Trouble I am having is create a dual wake system for the ship. 1st wake is the plowing wake on the Blow and the 2nd in the Aft of the ship making the ship wake from the props. The other thing is the Dreamscape is very old and has never really updated to use the Raytracing render engine. It is still using the default scanline.

Is there a 3rd party plugin or freeware render engine that Dreamscape would work with or a replacement render engine that can replace the default scanline that is faster.

I would like use the Raytracing render engine if possible and Dreamscape.

If not; does anybody know how to create a very realistic Ocean, Wake system, and Enviroment. That would change or adjust to the horzion also.

How Dreamscape works is by adjusting the horizon by attaching the camera to the ocean. Then adjusts the sides and lenght to cover the camera area. I can change the camera and the ocean and horizon changes too. Pretty sharp!!

Any help.... or am I hearing the rope pop and rubbing?
Thank you time and skills.

i work with dreamscape on a daily basis because there is no alternative for max yet "except for a plugin that currently beta testing named flood surf"

Basicly you should make low poly copy's of your hull shape and use those to simulate the foam.

attach one to your ship's hull in the exact same place, and for the foam generated by the props you should add another copy behind your ship just to generate some foam, because foam disapates at a quite decent rate if you had a long ship it would be visible as seperate foam trails.

if you have a smaller vessel of say 20-25 m you really should stick to a single trail


afterwards you need to bake your own proceddural map to make the foam look good, if you have an account @ sitni sati's website there are some excelent examples on their forum



as for the render speed i can agree that it gets quite slow.. we just bought 5 Q6600 machines with core2quad proc's they manage to churn out an amazing 7 min per frame on our scene's
"500k-800k poly ships and 1-2 mil poly's in ocean" where our old render pc's used to take 30-40 mins per frame "3.6GHZ single core cpu"


as for your horizon issues many renderer's have something thats refered to as a CSG

for brazil its a CSG option to enable in the renderer for vray its a seperate piece of geometry called a "v-ray plane" both options will add a plane to your scene that extends infinitly "only problem with this then is that you cant add any sections to it althou vray displacement works miracles when it comes to displacing water using a noisemap ;)"


here's an older testrender with foam

And some of the nordnes wich i attached
quality isnt the highest posible but that was because of the deadline, we just didnt have the time to test on a higher resolution foam map

I just joined this forum and have learned I cannot send a PM until I post five times. Thus, until I have my five posts, if Archetype or any of his friends reads this I would very much like to communicate with him and ask a couple questions!
