Vray Sun through Glass

[aflack]

For some reason when I set up a vray sun and sky the vray sun doesn't seem to shine through the glass at all. I get some light from the vraysky, how-ever if I hide the glass the whole scene gets blown out with loads of light.

 

Its like my glass isn't letting hardly any light through at all. Its just standard glass really with reflection and refration set to white with fresel reflections set to on.

 

Also I don't want the vraysky to be displayed behind the glass I want to use my own background photo when I stick this in the Max environment map slot the light in the scene stays the same but the background comes out black.

 

Please anybody have any ideas, I need to get this image done by tomorrow night and its driving me mad.

 

Thanks

Ok I sorted out the sun through the glass problem, I was using a converted egz glass material and affect shadows is turned off by default so thats fixed now.

 

Any idea about the background?

 

Thanks

Could you use a plain object with your background image mapped onto it? This would give you a better degree of control over the way it maps and you could make it so your map was a VRay light material so it will have an effect on the overall lighting/coloration of your scene (kinda similar to HDRI). Just a thought.

I would suggest you leave the Vray sky as background and check the affect alpha at glass material and then save render as .tga with alpha stored in. Than in Photoshop simply load selection of alpha chanel and you copy that in new layer. That way you remove the background from render, even through the glass, so you can stick any background you want, adjust it as you wish, make color and brightness adjustments etc. This work best for me...

Thanks I'll try that!

On your glass material, check that your fog color is set to white, and check "affect shadows". U should also copy your vray sky on your background color, or set it to white, to see is there is any changes.
