water
Re: water
yeah, just do like Pibuz posted and post result (I hope you did't forget to reverse faces to get normals pointing outwards...).

Re: water
ok.. i know you ppl did it here but i didnt understand how to make more rippled water
did something finally
edit:
not as good as u guys but... its an improvement

Re: water
Ok. You already used a map. Fine.
My next tip would have been to add the map NOT to the group, but to the faces, to be able to control the map's scale. I don't know what you did

Re: water
well i did put the map the one was posted here earlier, i have put the map on top of the upper Face of the "rectangle" water Group, was that good?
but when i want to have more groovy and shaky water i need to play with the maps scale? isnt bump doing the shakes?
oh i have much to learn
i think i got it... omg..
i mean i didnt render yet but i thought about it.. what i am suppose to do is basicly apply the map (material itself) only on the upper part of the group but what will be with the rest of the group? will it be rendered along the way? do i need to make the rest of the rectangle faces transparent?
i am thankful for you helping me thank you very much!

Re: water
I think you should remove bump and just keep displacement. Not sure if it will help but nothing costs you to try
Re: water
Also, have you enabled subdivision in the mesh settings?
Re: water
For caustics you need a bright small lightsource like a sun.JamesM wrote:Hi everyone, I need some help with the water caustics.
Your scene seems to be lit by a HDRI without a bright Sun (no hard shadows top spot!)
Use displacement for caustics, and drop the bumpmap.
Finally caustics from Indigos Sun system are hard to calculate...

Re: water
Hmmm, interesting stuff this. So I'm getting lots of caustics as seen underwater, but you can't really see them from outside. Essentially identical settings as Lape on pg 1.
Also I'm getting some weird little artifacts in the underwater shot, the straight/square bits. Any idea what causes that?

Re: water
Um, if I lower the displacement value on the map, (to 0.005 rather than 0.02) the square artifacting gets worse. You can see the caustics better from the top view now, but you can also see this glitchy stuff too...
Is it subdivision settings? I have to have the water mesh (cube) set to subdivision 8 or 9 or I don't get any caustics.

Re: water
Did you set the top faces to smooth shading?
Also, don't use view dependant subd. Seems to be a bug where not all faces are divided (even when they are in view).
Use these settings:
Subd smoothing on.
Merge verts off.
View dependant off.
Thresholds at 0.00.
You could also try the smooth option for the displacement map.

Re: water
Aha! but if I leave view dependant on, leave subdivision smoothing off and set curvature threshold to 0 instead of 0.1 it works...
Thanks for your help
EDIT: Wahey! I Like this. It has absolutely no practical application for anything that I use Indigo for, I'll never have a need to render underwater caustics, but its still very clever indeed.

Re: water
Thanks everybody for the tips,i'm progressing with the caustics but not good enough, if somebody keep helping me i'll be so thankful
