I need Help With Shaders

Hi guys, So I wanted to make a Dial on my tank to show the CD, I didnt want to use GUI for a reason I dont really want to get into atm. So what was Suggested to me, was to use shaders and use alpha masking to make part of my material Selection Dial invisible.

After 1-2 weeks of me banging my head against the wall, I finally made this work with the help of an asset named "Advanced Dissolve". I use one of its shaders along side a material of my own to mask the dial.

It finally worked and I was so happy, Only to notice that this was getting applied to all my RTS units using the same shader....



Now I have come across this before with a different asset, however, that asset also came with a script to manipulate the alpha (no masking), and it only effected that individual Shader that had the script attached to it and not all the other units, ofc, even in that case, if i had manipulated the shader directly, it would have effected all the units with that shader.

So I did some research and I cam across this post:

This suggests that if I use [PerRendererData] before the shader properties, it would do exactly what I need. and just to be sure, I added this to every single property. but it didnt work.

please help, I only started programming about 3 months ago, and shaders is just too much for me lol
