Vray + Maya 2013 caustics problem and more.

Hi all,

I have created a bathroom scene but I run into trouble with the caustics.
When I render without caustics the scene looks normal but really misses the caustic effects.

Here you can download my scene file: (7mb)
Updated scene file, fixed the texture link:

You still need to download the other file for the textures, just replace the old with the new scene file (badkamer.ma ..."badkamer" is Dutch for bathroom)

(Be aware that every time I start the render, vray renders camera1 even though in the settings the persp. camera is selected)

Scene without caustics and GI:

render with Gi and caustics:

Problem is very clear...

Could someone take a look for me? Would really appreciate that.

Then another issue, when I place a vray light source behind a piece of glass, this is the result (No GI and caustics):

Is there a better way to create real looking spotlights with glass in front of it?

Further, I would like to know if the material for the water is real enough (settings).

One last problem, which could be of importance and I have in all my maya+vray scene's:
When I use a vray camera, the scene becomes all black (lights are set too low, lumen). When I use the normal maya camera, normal lumens values are way too bright...
(This is the reason why the render is black when the vray camera is selected)
So I really have to set the lumen to insane numbers (1000000 for example) to light a car in a hangar (maya set to 1 unit = 1cm and modelled my models in scale (so a car is for example 400 units/cm)

If I could even solve one of these problems, I would be very happy!
