#Sub aquamercurial…
23 messages in this thread
Looking for awesome suggestions/examples of super incredible,
mindblowing, bleeding edge, headcleaning underwater/underliquid
looks. I'm not looking for photorealism here, rather I'm going for a
combination of realism-surrealism (probably a bad description
considering surrealism is a specific art movement that I probably
won't be faithful to in this peice… but you know what I mean,
right? <g>). AND, I'm trying to do a surface break without using
water SXP (don't have it, don't have budget for that effects group
🙁 ]
my feeling is to use ripple.pxp which comes with 3ds for the water
surface. For the lighting create a projector spotlight which uses an
animated ripple .flc bitmap to create those interesting light
pertubation effects that happen underwater. For this, I imagine you
could use a rippling object shot from above with an opaque white
material and harsh, glancing lighting. You'd get a nice cycling
ripple gobo .flc for your spotlight(s).

Like minds… <G>

Ditto <g>. I'm mostly interested in image processing suggestions to murk up
the scene, add atmosphere like looking through a glass of iced tea, or tears,
or something.

John,
I'm doing an underwater scene myself but I'm just wrapping up on the
modelling now, so I haven't messed with the "look" yet, But, to murk up the
scene, try this in Pstyler,
Open up a frame and use the duplicate command to make a copy it. Apply
a guassian blur to it (around 10, I think) and then do an Image.. compute…
blend and set both copies of the frame. You can try various settings, but this
should give you a nice hazed up image without losing any detail. I'm going for
a realistic look in my stuff right now, and this, along with some other things,
should help alot. I picked up this trick in a mag (don't remember which one) in
a little snippet on how atmospheric haze was added to a digital matte painting.
Hope its of some use,
David
Sounds like a good tip. The only thing is there are going to be quite a few
frames, and I don't think the new Pstyler does batch processing…

>> I don't think the new Pstyler does batch processing…
No, but it will do macros. I haven't tried it yet, but I'm sure you'd
have to initiate the changes to each frame by hand, so it would still be a long
and tedious process for a large sequence, well, even for a small one I guess.

Just a thought, don't know if/how it would work…
After rendering the entire final piece, map the resulting TGA's to a slightly
rippling face. This may be going too far, but may give that
distorted/refracted/wavy underwater look.
Not a bad idea, Wade. Tests forthcoming…

Those were my feelings, too. We're definitely thinking along the same lines:
I've already settled on ripple and the projector lights, too, and will either
use a hand made caustic (perturbation) flic, or digitized video. The one area
where I'm a little blank is image processing. I'd like to soften/murk things
up the way they look underwater, or through tears, or through a glass of iced
tea <g>. I've got some things brewing over here, but I'm game for all
suggestions.

John,
I'm not sure if post-processing would be necessary, especially if you use all
the things you mentioned plus the aqua fog. However, I just had an interesting
thought about rendering the sequence in video post with an entry in the trans
column which would be an animated grayscale wavy flic effect (values of the
grays might range from rgb 0,0,0 to 50,50,50). Possibly the same flic you used
for the projector spotlights. This would enhance the effect that you were
passing through diagonal fronds of light refracting down through the water. You
might need a first entry in the vp queue with an appropriate solid colour or
gradient or something.
Gosh, this is interesting I wish I had a PAR right now to do some experiments
with.
Martin,
Nice idea about the light beams passing through the water, have to try that
with fog. See what the effect is.

Cool suggestion Martin!!! I'm going to try that when I'm ready to do the
underwater experiments. I'm tied up on a 'real' job right now, but will be
getting to this project sometime in the next week or so.

John,
I might give my suggestion a try myself to see how it looks – I've made myself
very curious <g>.
Same idea as I had. How about creating an animated object using ripple,
duplicate it twice, rotate the copies some, make them transparent but shiny,
put in a light and a camera and render for the water ripple map? I think it may
yield a good result.
David T
Funny you should mention that, I'm starting all my water effects test right
now. The caustic flic with just the right amount of layered fog, light, and
tint yeilds spectacular results!
I'm going to do surface next, and was going to try exactly what you
mentioned… great minds think alike <g>!
John Tissavary (La Luna cie)
Yeah – Great minds think alike… and so do ours! <G>

John, you don't need Water.SXP, Ripple works great all by itself, you
just apply the process a couple of times to different areas, and then
morph between the variations. As for underwater, there's one on the
CD with a shark in it which might give you some ideas. Basically its
fog but light blue best way to get that underwater haziness. If you
want some glints you can morph a flat mesh in the background with an
opacity map with some glints in it that undulate. Gently swaying
sea-weed would be nice, morphing plants, lets see… I used a linen
texture for water once and it gave a nice differentiation to the
water, like patches of dark and light. I'll see if I can dig it up,
its way cool for the ocean look and if you put it on the surface with
the camera looking up through it the effect would be real nice. Any
other wildness you had in mind? <G>

Hmmm…. fog. Seems I use that a lot. I don't like how homogenous it is, but
I'll definitely give it a try! The plants sound nice. Let me know if you find
them.
thanks,
