Ah If you mean the color of the chams, I did change some to my preference, but what do you mean by alpha? And only XYZ chams can fix the invisibleness (using Red color), unless I spectate the target in 3rd person view (As SI, to an invisible survivor), in that case I can still see an invisible survivor with his visible firstaid kit and gun. DME chams won't work

alpha is transperacy, the th4 color. it goes red, green, blue, alpha for colors
I just never heard of this issue, only someone once reported me this and it was because he used backtrack chams on 0 alpha by mistake, on css someone reported me the same but I'm 99% sure it was the same thing with alpha chams, I just never got a response from him

Unfortunately it seems that my case falls into the 1% left xd. Here my color picks for the chams, as you can see all of the alpha are above 0
