Non desired purple shadows

Shadows appear to be purple after multiple attempts adjusting the lighting within the scene. First thought is lighting information is being pulled from the Skybox. What is the best way to fix the shadow color? Scene is built for virtual reality.

 

Is there anything that is purple in the scene, that could be emitting this or the light could be bouncing off of?
Any stray random lights you forgot about in scene possibly?

 

There are no purple materials in the scene. All lights and emissive materials are white. Also all the geometry is set to static.

 

Finally found the solution. The indirect intensity was way too high and a light probes background was set to blue instead of a gray.

 

Glad you found the solution. I knew it was something bouncing. But didn't see any blue lights in scene.
