Is there a limit to the amount of water you can add to the map? I the past I had never ever gotten water to work, no tutorials worked. I was finally able to add a little bit of water to one map without it crashing. However, I'm trying to add more to this other map I'm working on, but now it doesn't work for me anymore again. I've followed the water tutorial twice now trying to set it up for this particular map, once with kashyyyk stuff and again with bf1 naboo stuff. Both times, it crashes in game when you look at the water for long enough.

Any munge or log errors?
Can you post your req setup?

no munge log or errors
here's the req

Water is really one of those finnicky things. I'm in the same boat as you. Sometimes it works, sometimes I get nothing.

I've had the crashing problem when there's lots of water in a map, and I've always assumed it's just a graphical issue. Looking at the water for more than a second or two, or whipping the camera around too fast to look at the water caused extreme lag, and then a crash. Reducing your graphical settings might help some.
