Multilayer mtl problem!!!

[fa2020]

Hi guys,
I have installed Corona 1.4 on 3ds max 2016. I want to add a logo to a transparent plastic material so what I need is a mask map (Pure black&white) of the logo and the logo map(colorful). I link the transparent material to the main material button in multilayer material and then I link the mask map and logo map to their correct places in multilayer material. But at the render time, IOR(refraction) of transparent material is changed unexpectedly. I know that this is a bug. Please help me. How can I add this logo to the transparent material?????

this is fixed in daily builds (you can try them now - see the daily build section of the forum) and will be available in the 1.5 stable build in 14 days
