Talk:Water (shader)

What about water that refracts but uses a cubemap for reflections? Is that a "semi-expensive" water shader? --Mungo 11:18, 19 Jul 2005 (PDT)

The entity Water_Lod not works on CSS. 04/12/08.

Water problems

Hi! I got a Quadro FX4500 and all water shaders run badly (they simply doesn't appear). Just a note!--erwaitin 09:20, 22 February 2009 (UTC)

• You should get a new graphics card. Just sayin'. --Super200 07:25, 22 August 2011 (PDT)

$dudvmap Redirection?

Why does $dudvmap redirect here? Shouldn't it redirect to Du/dv map? --Super200 07:21, 22 August 2011 (PDT)

I think this is the only place where they are used. I don't think they even work any more either. --Artfunkel 16:20, 22 August 2011 (PDT)

Houdini file example?

Any example of those Houdini file, where Valve creates that vortex and other effects for bend normals? --Xuyase 11:58, 29 August 2011 The flowmap image on the page. FelixGriffin 14:16, 29 August 2011 (PDT)

A developer by the name of Dmitry Barannik released a PDF on how it's done inside of houdini, it also looks like he released his files created with the method (and even the houdini file itself). The PDF can be downloaded here And the pack with everything else Here. --Glitchvid 16:59, 11 June 2013 (PDT)

Thank you Glitchvid for posting it here! It was created for UDK, so maybe you need some tweaks, like inverting red/green channels, to make it work in Source. --Xuyase 15:55, 16 August 2013

Yeah, I think both the R and G channel need to be inverted, although that can be done in houdini for simplicity. A large hurdle to getting it working was actually importing the geometry. You will need Maya: just use the Export to Maya (with the geo selected in hammer) feature and you will have it in Maya. Then export it to a format Houdini can work with, then do the rest of the workflow with the model to get your flowmap. --Glitchvid 21:20, 7 September 2013 (PDT)
