water

[Ros. Riha]

what is todays state of affairs?

I need to have nice water:

On one hand, I think of caustics, on the other I would like to use SSS - but it was said these two do not go along well - what approach to employ?

 

[Ros. Riha]

as of caustics - I thought caustics needs to have solid volume to come into play, in other words there would be no use of caustics in the case of one face as Roy suggests for pools - am I wrong?

[Marc Chaumier]

I use region (one face) as the pool water and play with caustic. The play on procedural bump (no diplacement) produce caustic variations.

[Ros. Riha]

so, to be 100% sure - CAUSTICS DOES NOT NEED SOLIDS, IT AFFECTS ALSO ONE-FACE SURFACES?

[Marc Chaumier]

I think that caustics doesn't need solids, but when I make of some assertion, Roy comes to say the opposite ;o) Joke! It would be nice if you try to model your water with just one region (modelisation tools, solids edition, copy faces) as I said it a little farther.

[Marc Chaumier]

Here is what I got with x&y at 0.2, z at 1.0, strength at 0.08.

[Ros. Riha]

very crude, but this is what I got with rubble at akinlolu´s settings (x,y,z 1500, strength 0,044)

In your case, z should be always less than x,y - you have it vice versa...

How come my preview looks like this after all the above parameters?

[Marc Chaumier]

check the units, and the size of your sample.

[akinlolu olugboji]

Check the units in millimetre.

[Marc Chaumier]

So, here is the problem, I work in meters and so in my autocad, 1unit= 1 meter.

But check the size of the sample anyway...

[Marc Chaumier]

And now, after 250 pass. I think my settings are good for little surfaces, perhaps for an ocean, I will try something else.

To me this is rather a lot of motion for a pool of water with only wind activity. Looks nice I must say. IMHO should be more like this.
