However, you failed to mention Blitz so it won't show up when I do my monthly check of Blitz videos on You Tube - using the keyword Blitz, BlitzMax, etc.
Yeah, sorry about that. Technically it's not Blitz yet, as that was recorded in FX Composer. It will eventually be BlitzMax and TV3D when it's in my engine though.
I have exactly same effect in B3D with Andreymans library, and its damn fast..
Well it probably won't be exactly the same effect, because I think you can't do what I've done with the UV coords ( it's not even a recognised technique, just something I did by accident trying to do something else, hehe. ) But yes, it's basically environmental bump mapping to get the smoked glass effect, which is what Andreyman's library does.
His demo is what gave me the idea actually, as I thought his water didn't look much like water, but did look a lot like moving smoked glass. I assumed he was using a cubemap though, is that not right? I only use a flat texture there to save 5/6's of the VRam.
