How would you do this?
show user profile  loki
I need to composite a boat into a sea setting soon. I don't know how to do it and how to do all the bow wave stuff.

this is the kind of style i'd like to achive:

any tipps (3d/2d) tuts as well as resources of images on the web etc are well appreciated!

how real does it need to be?

not ultra realistic. you need to get that the boat is moving (it's a sailing boat performing not more than 15 knots), that water is flowing alongside. and it's a sailing boat hence i don't need a propeller vortex behind it.

what does your plate look like?

what do you mean by plate? the groundplane? i made several tests with a highly subdivided rectangle which i applied a noise modifier to. looks not too good IMHO. to..CGIish

i assumed when you said composite that you would be getting a background plate (ie a photo or footage) of a real ocean.

if your doing it all cg, it's almost easier. look up tutorials on creating an ocean scene. it's pretty simple.

what rendering system are you using?


i remembered an old trick i used to use that gave good results always, use two noise maps, one within the other but the one that's nested (inside the other noise map); make that one 10% the size of the one surrounding it.

i hope that made sense. play with the over size till it starts to look right.

its really easy to do in realflow, with awesome results- and can get as much realism and detail as you want

doing it in realflow is major overkill for something like this esp when it's a still.

oh i didnt know he said it was a still? if so then yes overkill, if you want animation then it might be more suitable

he didn't explicitly but i would guess that if he's asking the questions he is; if it were an animation he would def mention the fact.

Hey thanks for the replys!

To clear that up: yes its going to be stills. I'm not quite sure which renderer i am going to use. The boat is nurbs geometry so importing and handling in max is rather nasty. I'd like to stay with vray for rhino or Bunkspeed hypershot.

now for the water: It would be awesome if i could get the bow wave etc as geometry so i can leave out the part of importing and re-texturing in max. don't really know how to get started on it. does realflow give me real (polygonal) geometry which i can export from max?

yes. you can create a wave plane, or normal fluid sims. then simluate it hitting aginst whatever you want ie the boat, and then you get geometry for max- not sure if you can edit the geometry after in max- if thats what your asking- but can edit it in realflow and just export again if need be.

but its prob just easier for a still using soft selection on a plane, turbosmooth it and add details in zbrush

"but its prob just easier for a still using soft selection on a plane, turbosmooth it and add details in zbrush"

considering your pipline, i'll have to agree.
