I did a search, nothing came up.

I would assume RTT stands for rounds-to-tracers, so the RTTRatio in .inis would be the ratio for how many rounds for every tracer.

I have a gun that has two rounds, a normal round and a tracer. It is supposed to shoot the normal round first, which acts like a beacon, then it shoots the tracer which teleports your actor to the beacon. I have RTTRatio set to 1, which should mean 1 round for every tracer, but it only shoots tracers.

What is the magic number to make weapons shoot 1 round then 1 tracer?

More accurately, it's "one tracer in how many rounds". The variable name is a little misleading.

To shorten the above posts, make the number 2, one tracer for each 2 shots.

Thanks, I got it to work.

I had to switch the rounds around though, for some odd reason weapons shoot tracers before normal rounds.

It's hardcoded that way.

Not that strange, IRL you would use a tracer to both see stuff and mark where the bullet lands. So it wouldn't do ♥♥♥♥ if it was the last round in your mag....

You might have the last few or near to last round as a tracer, to notify you that you are almost out of ammunition.
