Great to have the rhino lights back!! So much easier to quickly create directional (spot)lights again. However, the intensity settings have me puzzled: "and light power is scaled according to the document unit". How can i have more intensity? What unit do i have to change?
Did a quick test with a rhino spotlight through default polyurethane sss.
Used realistic camera settings, but have to increase the intensity to the max in multilight slider (and rescale to 10000) to have enough effect.

Could you tell me what the document units are vs. what overall size the scene is?

doc units are mm, the block is about 25 mm long

Hmm...that seems to work okay here: these images are mm scale, a 25mm cube, camera EV=6:

Not that this will work great in all situations - scale the model to nanometers or parsecs and you can be pretty sure you're not going to get any useable result. This will all be extended out in future versions with custom materials or parameters being defined for each light while inside the plugin, but for now you'll probably run into situations where you need to open the MXS in Studio and adjust the power of some emitters. That might seem like a pain, but turning these lights into actual emitters and geometry that work using arbitrary scene scale isn't really an exact science - even if you need to adjust emitter power in Studio, you will still save alot of time over having to create all of the geometry yourself.
