Material with Opacity Channel shadow question

Hello,

I am currently working on a personal project in C4D and am new to using Octane.
The project involves a product with frosted glass bottle, which includes a label on the bottle and an aluminum tube inside it.
The frosted glass bottle and label are created using a mix material with an alpha texture driving both materials.

I would like to inquire if there is a way to disable or remove the shadow cast by the label onto the aluminum tube inside.
Any guidance on this matter would be greatly appreciated. Thank!

Hi,
please use a Composite material, instead of a Mix material:

Then try to use the Ray Switch node in the Opacity channel of text materials, to remove the shadows:
