thx !

To add an HDRI from the Max background environment, check the "Include Environment" on any LightSelect pass (usually, an empty one, so you can control the HDRI separately). See the tutorial at https://www.youtube.com/watch?v=JRNxxzgUhSw (https://www.youtube.com/watch?v=JRNxxzgUhSw) which will cover adding regular lights, HDRI / Sky, and Light Materials.

thx ) for fast solution! and another question can i write this in exr, and then use in nuke ?
-
Yes, you can sure do that! One thing is Max always creates separate EXRs as well as the "all-in-one" EXR, so you may have some post-render file cleanup to do.

(in case you didn't see the other thread on using LightMix in post, don't use any tone mapping in Corona, and use an Additive mode in post to reblend the layers, then apply your tone mapping there as well)

iv use node from, from b stream and minus pass from shuffle with pass and then back it in mine stream in add! very comfortably for pass compose
