Old Caustics Help Files - updated info needed.

[sv]

The current Caustics Examples i have found:

http://www.spot3d.com/vray/help/150R...s_caustics.htm
http://xyz.cottages.polycount.com//l...vray/index.htm

and they reference Sph Subdivisions.
This has changed has it? Because i can't find this parameter anywhere. It's not object dependent either as far as i can find.

Also, are caustics resolution dependent? Like the LightCache....?

You can find this if you select the light, right-click in the Viewport and choose V-Ray properties (or, alternatively, the Light settings button from the System rollout in the Render Scene dialog). I think it is called "Caustics subdivs" now though.

ok, great, thanks.

Is the map resolution dependent?
Not from the looks of it now, but last nights renders i thought perhaps it was.

All looked ok at 600x450, then shocking at 1500x1250. But i think in retrospect the solution wasn't actually that good at 600x450....

And another question, if i have a saved caustics map at about 600meg, when loaded by other machines for the rendering, is this just loaded straight into memory, or read from a file like a proxie?

Many Thanks.

The photon maps are resolution- and view- INdependent; you can reuse the same map for different resolutions and views.

The GI maps are currently loaded all into memory at the start of the rendering (as opposed to proxies which are loaded during the rendering itself).
