V-Ray V-Ray for 3ds Max Issues
1

Hi guys, I seem to be getting a hot spot in the middle of where the camera is pointing. in the image I’ve attached even though the sun is facing directly straight at the camera the light seems more intense in the middle and fades out… note under the eaves in the centre they are white, but out near edges of house they are very dark.
Is this a camera issue or lighting.
I am using a vray sun/sky/physicalcam setup.

It also looks like you’re getting a lot of bounce light coming up from the sidewalk.
