water glass and caustic

[nico]

hi boys, a new wip.
this is a image experiment after see a picture of fryrender.
the first render is this but i want a colour glass and a best caustic effect.
can you help me?

You need better glass model (this is a bit ugly...) need thin glass one side.
Maybe try hdri?
Try this glass idea:

hi johny,
ok for surface i have it, for model i remodel the object tomorrow, the glass is on side as water
in this image no hdri...
wou think that it's necessary? what's hdri? (uffizi???nooo) i don't know the best hdri for one scene as this

[nico]

new render with change of model and surface.
no hdri
but where are the caustic? i have use 2 spot light

Did u turn on caustics in general tab and chose some preset on the photons tab under caustics?

[nico]

ohhh that mind!!!

i'ven't set on the caustic

[_mats_]

that should do the trick !

Please show us the results Nico !

I haven't used caustics at all, but saw some really really good Kray renders with it, need to start playing with that !

Matt -

hi matt, sorry for a long time but in the week end i work on my web site.
so this is the new render test.
i not see the caustic effect so i post the screen of setup and surface of glass (the first) and water (the second).
C&C

No idea... It should work. Can you post your scene?

[nico]

this is the scene and object

[jure]

Caustics are there, they are just very diffused because of your big light... You can see them in preview when Kray is shooting caustics photons. I also suggest you turn to indirect luminosity mode.

[silverlw]

Caustics are there but faint from those lowintense luminous planes you added in the scene. To see caustics photons from your lights you have to switch them to inverse square falloff, then you see very strong caustics.

[nico]

thank's for tips but with indirect luminous the render time is impossible

indirect renders faster than direct... I think your scene has something weird in it.

10 million received photons. This is rendered on a quadcore.
