V-ray and Sketchup- Strange Reflection Issue

[mrbawkbachgawk]

I've been having this re-occurring reflection issue in sketchup vray renders. There appears to be a circular reflection/shadow that dominates the facade relative to where the camera placement is(see attached image). When I back up from the facade and re-render the circle becomes larger. I don't think this is the sun for either the sketchup sun or the HDR map as they are located in a different direction as the facade is facing. Please let me know if you have any ideas of what's causing this and what might fix it. I cant be the only one! Thanks!

are you using simple plane for glass? or solid.

either or, you need to adjust your IOR. try with a simple value of 1, if the effect if gone, then you know it is because maybe you are using a single side plane as glass and the reflection is bending/ distorting your view.

Thank you! A value of 1 seems to work. I had to add a Refraction map to the metal panel and move the value to 1 as well. Everything seems to look right.

Are you using a dome light? Is this VR4SU 2.0?

 

Have you tried resetting your render settings to default?

It seems as if the issue has come back. Maybe my view angle had something to do with it. I am not using a Dome light however I tried one and had the same problem. I think it is an issue with the material parameters but I'm unsure as to what settings will resolve this. I've gone way high and way low on the IOR.

How are you mapping the HDRI to your environment? Can you pack the scene and send?
