Irradiance map and render layers

[MVS]

I have a scene with a number of different objects, and different render layers. A vrayobjectproperties node controls the primary visibility so that only one object is rendered on each layer, but all objects contribute to GI, reflection, shadows etc.

The objects are not animated, but the camera moves, so I create an irradiance map (multi frame, incremental, camera path etc.) from the masterLayer (all objects visible).

Can I use this same irradiance map on each render layer where only one of the objects has primary visibility, or do I need to create separate irradiance maps for each render layer? In theory it seems that the same irradiance map can be used (because all objects contribute to GI), but my initial tests seem to indicate otherwise (artifacts in the GI pass).

I don't think that this is going to work even on theory.
IM is view dependent and changing anything in the scene like making objects visible/invisible will affect IM accuracy and it will most likely produce artifacts in the animation.

as said it wont work. you could probably bake irradiance per layer and do render layer overrides to load different irmaps per layer.
