Cycles shadows?

note:
just found something
i’m using PBR with metal
if i set metal and spec to 0 shadow is gone!

so this would be more like a specular reflection is it possible ?

i remove all the shadow on all objects
and also on light source
i have only on emission light source
World does not seem to make any shadow !

and still get a shadow

what else is needed to get rid of all shadows ?

the blue line in middle is a shadow !

thanks

did a test with diffuse and glossy and don’t get any shadow or specular on objects!

so is there some parameter on PBR to get rid of this extra reflection ?

thanks
happy bl
