Odd emission behavior

Hi everyone!
Could someone explain mw why I have this kind of behavior?
Flames are on planes, with alpha channels and emission as light emitters.
When candles are behind glasses it's all ok, if flame is into a glass alpha doesn't work....
Thanks for your help!
Cheers

Check your Specular Depth in the selected Render Kernel; it likely needs to be set to a larger number

Hey Jayroth.
I did before posting, even at maximum value doesn't change...
Moreover, regarding depth, it owrks trespassing both side of glasses, it doesn't across one side only..
I checked and tried with whatever setting, it depends from emission channel but I don't know how to fix it.
Thanks

Hi, I was able to reproduce the situation, the way to yield the expected result:
1. the texture file should not be loaded as "alpha image texture"
(or however it is renamed in Octane C4D), but instead, as a regular "RGB image texture"
2. then can be plugged to both the opacity slot and emission.

It works!
Thanks a lot Elsksa!
