water
After reading through the forum and several failed attempts to create some realistic pool water (or water in general) I hope someone can push me into the right direction... though this probably was asked many times before
What I did so far:
-modeled a containern in sketchup
-modeled the water intersecting the container walls about 1mm
-tried to use the materials from the database like pool water and rippled water
I couldn't achiev any ripples or waves at all. Do I need to add a bump map or displacement map to get the waves? Or do I have to model the surface of the water in sketchup?
I'm using Indigo RT.

Re: water
use it as a displacement for best results in closer shots. Bump will do well otherwise, normal maps would make a nice compromise.
The database waters describes only the water medium, there is no surface detail involved most often.

Re: water
Ah, ok! Thanks for the map and for the hints. Now I get some waves. Unfortunately they are far too small. Is there also a button for scaling the displacement map? Or do i have to scale the map with PS?
Again some very basic question, but I just can't find the button...

You can multiply the values of any texture by changing the "B" (scale) texture parameter in skindigo

Re: water
The "B" parameter gives me the wave height or the size of the displacement, not the size overall. I would like to change the waves in length and width, and because there is no diffuse texture in Sketchup for my water, I can't scale the displacement map.

Re: water
my fault, should have tried first before writing and asking...
thanks anyway

Re: water
Yes, you can always define a texture in sketchup even if diffuse is disabled in skindigo. This will texture-map all the indigo textures.

Re: water
..Lape..how did you get it to work...
I've never been able to render water pool caustics at all! Please give me a hand...
EDIT: disabling GPU contribution actually makes it a little easier..
but still caustics are far from being calculated! damn
RE-EDIT: ..maybe I'm only a little too impatient..
Something is kinda going on under there... mmmmmhh... time to update my hardware?
BTW: what were your render settings? Supersample, resolution, glass acceleration on or off, method...

uuuuhhh, I, as an Indigo-noob should teach a long time Indigo user how to achieve pool caustics...
ok, see my attached settings....
Let me see what you can teach me (I know it is a lot):
WHERE do i find this damn double sided material for Skindigo??? I've tried to create realistic leaves for my plants, but I was not very successful using a blend material. And where is the "diffuse transmitter" material in SkIndigo? Or is this just some diffuse material with opacity set up in Sketchup?

Re: water
Sorry Lape: is that just a plane, the geometry you attached the displacing map to?
Re: water
No, it's a cube intersecting the pool walls about 1mm.Pibuz wrote:Sorry Lape: is that just a plane, the geometry you attached the displacing map to?

Re: water
And the same material is attached to all the other faces?
I saw I have samw results when using a much more simple specular mat for the non-visible faces, in order to spare some memory since the diaplacement iterations can be quite heavy to carry, RAM wise.. I'll post my try later thanks a lot mate!
