Have you read "Too many dumb pilots"? Feeling now like one. Things I want from the start of Iray in DS were rendering in HDR and multilight.
And all this time it was here, in form of canvases.
Just want to put it here if there is someone as inattentive as me.

Canvases - in Advanced tab in Render
Iray Canvas Tutorial
+ something on DAZ forum (that I didn't read except new versions anouncements, so didn't know :) )

Each canvas internally is 32-bit exr file, that stays after render stops if you not overwrite it with canvas with same name. Location on Win is you userDir\AppData\Roaming\DAZ 3D\Studio4\temp\render\r_canvases\
Want script to auto-copy it on stop. May be start using Daz sccripting after all.

Multilight - basicly you generate different files for different lights and sum it in Photoshop, so you can adjust your lighting without re-render scene. Maxwell can do it in realtime in render (and was first? not shure), Lux too, not shure about other renders.
