now first off weÓll create some materials, so get into the material

editor and seleect a new material, change it it vray material

- change reflection and refraction color to white

- check Fresnel reflections

- choose a very licht blue color as Fog color

- set fog multi. to 0.01

- check Affect shadows

assign it to the torus knot

now create a other material, also a vray material

for diffuse color select a light grey

and if you render you have something like this :

now we are missing the caustics, here we go:

get your vray renderer and goto vray:system

click light settings and select spot01

click Ðgenerate causticsÑ on

subdivs : 2500

multi : 100000.0

now go back to the render dialog and search for vray:caustic tab

click ÐonÑ

multi. : 4

search dist. : 0.4

max photon : 2000

and render it out you should get something like :

to get some better caustics change to

multi. : 2

search dist. : 0.4

max photon : 2500

also change the under vray:system -> lightsettings > spot01

caustics subdive to 5000

also add a meshsmooth to the torus (render Iter. 2)

then render it out

this is gonna take long, calculating the caustics but well,

and well thats it

hope this has been usefull
