Shadows in Vray for Sketchup

[Red33]

Hello, I'm trying to render an exterior, sunny afternoon image using the physical camera and an HDRI for GI and background and can't seem to get the types of shadows you'd expect from the time of day. In fact, I'm not getting any shadows at all. Could someone tell me what I'm doing wrong? I apologize that I don't have an image to post at the moment, but any help is greatly appreciated. Thanks!

Hey Red... I understand that you don't have an image to show, but its going to be hard for anyone to help you without it. There could be a couple people, maybe, that have had the EXACT same issue that you have and know EXACTLY whats wrong just from your description, but I think it would work out a lot better if you can find a way to post something for us to go on.

 

Good luck.

Ok...Here's the image. I guess I'm wondering what your settings would be if you were rendering a high quality exterior daylight scene. The time of day of the attached image doesn't really reflect the time of day I'm looking for, so please disregard that.

Hey Red - Are you using a skydome around your scene? It looks like, if you are, its blocking the direct light coming from the sun. You have to exclude skydomes from the vraysun so that the rays will come thru. If its not that, I am not sure if I can help you, because I don't use vray for sketchup, but it certainly looks like something is blocking your sunlight.

 

As far as settings for the sun go, I barely touch the default settings. The only thing that I do, sometimes, is decrease the turbidity and ozone. They have similar effects, and adjust the amount of 'haze' near the skyline. Other than that, I adjust the shutter speed on my vrayphyscam to get an acceptable exposure, and thats it.

 

good luck!
