Problems with sunlight coming through windows...PLEASE HELP

[charnjeevkang]

Hello all I am having an issue with interior lighting/effects, I have attached a jpeg of a very quick render I had done with sunlight coming through the window and I have attached another jpeg of how I would like the sunlight to shine into my interior space. But after much trial and error I still can't manage to stumble upon my desired result.

 

If anyone knows what the problem is please don't hesitating to message back. Thanks a million

 

The settings are default vray a part from the physical camera being turned on with a 300 shutter speed, as well as the environment and GI being linked with the sun. I am using vray for rhino.

 

(my render is named 'sunlight 1 physical camera')

On your glass material, make sure that under the refraction roll out you have "affect Channels" set to All. This is not default so you have to change it. If that isn't enough, then try adding a vray plane over the Window area, facing inward and tick the skylight portal box. This will help to extend the light from outside inward.

Also be sure too have "affect shadows" checked under the refraction settings for you glass.

Thank you so much for your quick response Corey, I edited the glass as you suggested....but something funny happens during after the render.

During the actual render the sunlight is shown onto the floor but once the render is complete the sunlight vanishes.

Also I am a vray newbie so I can't seem to locate the skylight button?! But thank you again for your quick response

Thanks mate

I have also attached image of the properties within the refraction rollout of the glass!! I'm not sure now if I've done it correctly?

 

Thank you for response as well erickdt

Thanks Erick. I forgot to include that.

I don't know where the option is in Rhino but if there is such an option to disable cast shadow, you should check it OFF for the glass geometry. Hope this helps.

Hey all thank you for all of your suggestions, they have been a massive help...I was using a pre-made glass material and I also had 'GI lights only' ticked. Once I had ticked it off and created a glass material from scratch and that sorted out the issue right away, thank you again for your suggestions
