The water in that game is AWESOME. _________________ The number 1 cause of death in games is panic. Add 870 posts to what it says my total is (SonicClang is my real profile)

It could be done using q3map_alphaMod volume brushes to set explicit vertex alpha and do additional foam/edge passes in shallow water: http://akiba.shaderlab.com/samples/ocean_2003-01-30/

That way the water vertexes can match up to them to make the alphamod work. If you had, say, a strip of beach right around the edge, with a strip of water running alongside it, you could blend the two then put an surf shader overlay over both of them to disguise the blend and use alphamod vol brushes on the seaward wide. I guess the surf shader could be scrolling but with alpha fade and a tcMod to make the surf fade away as it rolls up the beach. It would need a shallow sloped beach though to look natural. I've been thinking about doing something like this myself, and this was the best thing I could think of. Hope it makes sense.

Open up .pk3 demo files look for the water.shader, please recreate this with your own source, as it is illegal to use this as is. I pulled out the shader below, Ydnar can speak to these commands working with Q3map2 but I am pretty sure they will, this system gave me pretty good control and might be less overhead during runtime. It gave me the ability to control with brushes where the water was shallow, and where it wasn't. textures/water/subpen_clear { qer_editorimage textures/water/subpen_clear.tga qer_keyword natural qer_keyword liquid qer_keyword subpen qer_keyword add-on qer_keyword ocean surfaceParm water surfaceparm trans surfaceParm noimpact { map textures/water/noise.tga tcMod transform 1 0 0 1 0 0 tcMod scroll 0.01 -0.13 nextbundle map textures/water/noise2.tga blendfunc add tcMod transform 1 0 0 1 0 0 tcMod scroll 0.12 0 } { map textures/water/subpen_waves.tga blendfunc blend alphagen const 0.5 tcMod scroll 0 0.01 } { map textures/water/water_shadows.tga tcMod scroll 0 0.07 nextbundle map textures/water/water_shadows2.tga blendfunc filter tcMod scroll 0.07 -0.07 } { map $lightmap blendFunc GL_DST_COLOR GL_ZERO rgbGen identity depthFunc equal } } textures/water/subpen_transition { qer_editorimage textures/water/subpen_transition.tga qer_keyword natural qer_keyword liquid qer_keyword subpen qer_keyword add-on qer_keyword ocean surfaceParm water surfaceparm trans surfaceParm noimpact { map textures/water/clear_transition.tga blendfunc blend // tcmod scale 0.3 0.3 tcmod transform 0.85 0 0 0.85 0.1 0.1 } { map textures/water/noise.tga tcMod transform 1 0 0 1 0 0 tcMod scroll 0.01 -0.13 nextbundle map textures/water/noise2.tga blendfunc add tcMod transform 1 0 0 1 0 0 tcMod scroll 0.12 0 } { map textures/water/subpen_waves.tga blendfunc blend alphagen const 0.5 tcMod scroll 0 0.01 } { map textures/water/water_shadows.tga tcMod scroll 0 0.07 // tcmod transform 0.1 0 0 0.1 1 0 nextbundle map textures/water/water_shadows2.tga blendfunc filter tcMod scroll 0.07 -0.07 // tcmod transform 0.1 0 0 0.1 1 0 } { map $lightmap blendFunc GL_DST_COLOR GL_ZERO rgbGen identity depthFunc equal } } textures/water/subpen_opaque { qer_editorimage textures/water/subpen_opaque.tga qer_keyword natural qer_keyword liquid qer_keyword subpen qer_keyword add-on qer_keyword ocean surfaceParm water surfaceparm trans surfaceParm noimpact { map textures/water/opaque.tga blendfunc blend } { map textures/water/noise.tga tcMod transform 1 0 0 1 0 0 tcMod scroll 0.01 -0.13 nextbundle map textures/water/noise2.tga blendfunc add tcMod transform 1 0 0 1 0 0 tcMod scroll 0.12 0 } { map textures/water/subpen_waves.tga blendfunc blend alphagen const 0.5 tcMod scroll 0 0.01 } { map textures/water/water_shadows.tga tcMod scroll 0 0.07 nextbundle map textures/water/water_shadows2.tga blendfunc filter tcMod scroll 0.07 -0.07 } { map $lightmap blendFunc GL_DST_COLOR GL_ZERO rgbGen identity depthFunc equal } } The purpose is for a large body of the water btw, not the foam.

Sorry about the 56k, that sucks. I can't post the textures as it would be aganist the law, sorry about that too.
