How to Add a Texture on Top of Another Texture while Preserving the Former's Opacity?

Hello,

I’m trying to make a Translucent Material UI for Special Move Slot. The first image shows what I want to achieve. The Background is semi-transparent. But I also have a UI Shine Effect from an Artist that must be blended using Flipbook and ColorDodge. What I want to achieve can be made by using separate Images/Materials but due to it need to be blended using ColorDodge, I make all the textures in one Material. My problem is that, I cannot preserve the Background Texture opacity. There must be something I’m missing. But currently, the Background Texture is fully opaque instead of semi-transparent. If I use BackgroundTexture.A, it will make everything semi-transparent. Please give me your guidance….
