Please add a "Use MIS" option to Direct Illumination of LightMtl.

Direct Illumination of LightMtl will become dark by RawLight elemnts, if GI is enabled.

Please add a "Use MIS" option to Direct Illumination of LightMtl.

Or are there any other solutions?　(use premise about LightMtl.)

The light material without MIS will be way too noisy. It is possible to fix the lighting elements in other ways, and we will be looking into that.

Hummmmm

work with many retail stores .. Large spaces of 800m2 to 100m2 store.

Generalemente filling the space with VrayLightPlanes but I require use of lights forms only give the IES.

The renders are quite a problem when using IES.
