With PB it seems impossible to deactivate shadows by material.
It is like EntityRenderMode(Entity, #PB_Entity_CastShadow) is called
by PB itself. Click F5 and the shadow should be disabled because of
the new material. Currently only a call of EntityRenderMode(Entity, 0)
will deactivate shadows for that entity.

I don't know what could be the cause of that (we don't call any shadow functions when reloading a material). Is it the same when using a regular material script (without reloading it) ?

[PMV]

Yes, and if i remember right thats how i have found that bug.
In material "receive_shadows" is completely ignored.

slightly changed example:
