Even More Shader Stuff + A Technical Question
this is the last one for a while, i promise.
waterfall, now with refraction. and something that's been on my to-do list for a long time,
dp_water. i prefer this over my
previous water test.
I wish we had something that good looking for waterfalls in Quake, to complement DP Pretty Water.
well, you can. this is basically quake in darkplaces. if you or someone else wants to use it for quake i'll upload the source files for the tests i've shown. i recommend making your own, though, as you'll probably get better results. these assets were made hastily for the sole purpose of getting it working. the waterfall is just noise with a directional blur and some squiggly lines to break up the uniformity. the normal map used for the dp_water was generated from an image created with the "render clouds" filter in photoshop.
technical question, probably for the engine folks
you may have noticed the bright seam along the edges of the dp_water caused by the reflection distortion revealing reflections that should be obscured by geometry. this is just plain awful with fog and/or skyboxes. can anyone point me in the direction of a reasonable "fix"? I have some pretty hacky ideas map-side, but they're just a band-aid.
another strange thing, that's not something that needs "fixed", but worth noting. when reducing r_water_resolutionmultiplier value, you have to increase the offset of decals else their reflection will z-fight.
