Sunlight Shadows

[grasshopper]

How can I get the sunlight to cast sharper shadows through my glass?

I have tried various refraction values but with little effect. The sun just seems to diffuse through the glass and you see no evidence of light falling into the room.
I am using default sun settings and a Physical Cam 8 f-number, 125shutter speed & 300iso

Glass is Vray mat - white diffuse, white reflect, fresnel checked. IOR 1.6.

Any help appreciated

hello, you have multiple solution for this problem:
1- use a standard material with low opacity
2- select your glass objet right clic and go to properties and uncheck Receive shadows
3- in your vray material check affect shadow

Or go to the exclude section of your sun and take 'cast shadows' off all the glass.

Theres a thread aout this at the moment.

something doesnt look right, do you have affect shadows checked in your glass material?

I second that.

yeah, in your glass material check the box "Affect Shadows" in the refraction group. Set a little fog color and the multiplier to something around .01. you will have to experiment with the fog multiplier as it directly relates to the thickness of the glass object.
