sun intensity

[Lebjos]

Hi,

 

I've done a bit more since my last post when I was having trouble with interior lights as well as the sun crashing vray. I got an alright render with the lighting effects I want but still am kinda wondering about the sun settings.

 

The materials on the inside are not washed out but the materials on teh outside get washed out by the sun, and it still seems like it is very intense. It is on a super low multiplier and im starting to wonder if maybe it is my GI settings that are making the scene overly bright on the outside.

 

any advice would be greatly appreciated. thanks.

Post your settings for your "Sun" and your Vray settings.

hey sorry i didn't post the settings in the first place, was getting a little late and i was tired . thanks.

in reality your exterior should be totally blown out, to balance both interior and exterior would be unrealistic of true photo if you are going for realism. The sun is much stronger than interior lighting.

 

quick google image search for an interior....

thanks for the advice, makes sense. I'm not going for realism persay, but my project is all about light, so i'm trying to get across the point of the quality of light that the facade and roof openings allow into the space. My confusion lies within the realm of whether the best way to get the shadows I want are from the sun or vray lights? Ive been through a couple tutorials and have noticed that many interior (photo-realistic) renderings use a combination of both. I can post some renders of the facade and roof if you would like. Thanks for the advice and quick response.

another quick question is what is the best way to change the vray sky to something that more appropiately matches the ammount of light that the sun is emitting? photoshop or apply a different map to the slot?

I'm 50-50 between inserting the background with a rig in the model vs. using the vray sky and replacing the sky in photoshop using the alpha channel.

thank you, there were some other things that i was wondering about in a couple of those weeks as well =). Thanks again.

Also, in your glass settings, do you have affect shadows checkes in the refraction parameters? You should.

[Lebjos]

it wasn't, and that makes a very nice difference . Thank you.

Hi, When using vray sun/sky it is best to become familiar/comfortable with using the vray physical camera and leave the sun intensity at 1. This can apply to interior and exteriors in my experience. You can try lowering it, but it is more controlable when adjusting the camera instead. Hope it helps,

Best regards,
