Please help me with the glass object of octane for max 
Q1: I modeling the glass object , which is a single box(about 8mm thick) and apply a specular material with opacity=0.3 , transmission=white(RGB=240,240,240) , but when I create octane daylight , the sun just couldn't coming through interior room! But when I hide all glass object , it does!! Please help me , I want the sun shinning through glass (without glass reflection , it 's ugly!!especially with interior rendering)
Q2: How could I turn the ies light invisible? It always render visible~~also with the octane plane light(disk,sphere whatever~)It's that possible to turn off?or it's that another way to create ies light without being rendered?
Please help me ~~~I am dying rightnow~~

1) currently you can't get caustics with sunlight (there are several forum post complaining about that 
refractive promised to improve this in an upcoming release
2) to make an light emitting object invisible, just turn its opacity down to 0 - it will still emit light (don't know if this works for ies, as i don't use it)

ps: if you use a glossy material at low opacity, you can fake architectural glass (sort of), and won't have this problems with the sun environment...

ya, hope it will work for you; in fact the sun environment is still problematic (most of all with the direct light kernel). and if you have tried the opacity trick on ies emitting objects, just tell if it works as expected - may add it to my tips & tricks list...

no...I am sorry~~cuz i couldn't find any ies "invisible" option of octane ies light tab,could it be possible to apply a "material of ies" to a single plane?

you are welcome
as for the ies lights i was only guessing, because i don't use the max plugin. apparently it is different from the standalone (there you can just apply an ies map to a diffuse emitter)...
