Good idea but not a viable option for my map. Everything is inside of a cave and theres not a whole lot of moving going on. And its within about 2048 that my FPS goes to crap so a pretty good ways.

I am thinking it is just a setting that is going nuts. I dunno though... I am hoping Boojum has some idea why.

Not sure why that's happening, it didn't for me in my test map, and I never get near 200 fps to begin with so a drop would've been more noticeable. Would you send me the map and let me have a look myself? PM me a link if you have someplace to upload it, otherwise you can email me it, aboojumsnark [at] gmail.com

It seems to have fixed itself somehow. I have recompiled a couple times and after building cubemaps it does not seem to do it anymore. If I have the problem again I will shoot the vmf over to you.

Thanks very much man, it looks wonderful!

*Edit*

Just to make sure, this is fairly cheap correct? I have to large waterfalls in my main choke point and don't want everyone lagging out lol

It shouldn't be much more expensive than any other cubemapped surface. The deformation of the reflection might add a little bit more, but with everything else that is going on in a game I don't think it'd make much of a dent.

Im using something similar to this with my water fall in avantiville...


I got a question for ya


How would one use a water texture on a vertical face? Can I change one of the attributes in the vmt to allow me to use water going up n down.... its just in the skybox so no one will be touching it:

Right now its just a clear scrolling water texture... it needs a blue color underneath it, but it wont let me use water on a vertical face

You "cant" use a real water texture on a vertical surface. A real one with reflection, refraction and the color-tinting of stuff behind it just won't function properly on anything but a flat surface.

There are a plethora of VMT parameters that have to do with real water, and when making fake water like I did it's easier to start from something closer (the hydro cheap water).

My only suggestion (unless you just make a water-like image) if you really want your water looking bluer is to try tweaking the $envmaptint parameter over to the blue side (it's an RGB value, so raise the last number) which will make the cubemap reflection more blue.

would that scrolling work on a displacement?

P.S. that video in the above post isn't working.

edit: i clicked the title, it seems to play on the youtube site fine, just not through the hotlink.

Only by making a mod and changing the source code. That's really not dynamic water, just an imitation that follows a couple rules, but is really, really limited.
