"cat_glow_teammates 0" acts as "cat_glow_teammates 1" until the respawn friendly-viewing wallhack is disabled about cathook HOT 4 CLOSED

I don't understand what you meant by that.

here are some screenshots:
here I am about 15 seconds after respawning. glow is working normally, with teammates not lit up, as I have inputted into the cathook config. https://i.imgur.com/hCjky7J.png (teammates is off!)

Now here I am immediately after respawning. Notice the blue text above friendly players - that is the "friendly viewing wallhack" im talking about. This tf2 feature breaks the teammate glow setting - as you can see, with teammate glow off in cathook, my teammates are clearly glowing. https://i.imgur.com/BBQYi9X.png

When the friendly-viewing wallhack disappears (around 10 seconds after respawning) the teammate glow also disappears, making me believe that the friendly viewing wallhack is the problem.

Yes, tf2's default friendly wallhack can't be turned off.

Fixed in 1c887af by making teammate glow fully transparent if teammate glow hack is disabled
