daily build 08-05-16 strange behavior with ray switch material

Hi, here an example of an strange shadow casting of a ray switch material with global slot empty, am i doing something wrong?

a little update: the casting shadow material slot is the reflection, also it only cast shadows on objects with pbr materials active.

Hi, can you share the scene?

yes, here ive upload it

Don 't use corona light material, use instead a Corona material with Self illuminate texture, otherwise it won’t work!

Yes but that also emits light even if you use a ray switch material when pbr is on
