Waveset/Dynamic Env Maps question

Postby Mystified Explorer » Tue May 27, 2008 12:30 am

I've been playing around with wavesets (which are awesome btw :D). I have a question, however - how do I go about making the reflections look right when the age I'm making is surrounded by an ocean? The age is an artificially built complex surrounded by ocean, with hills on one side (these are billboarded) and just the horizon on the other. The centre of my waveset object falls right in the middle of the island. How do I get it to reflect the island and skydome correctly? I've played around and have yet to come up with a good result.

Thanks :)

Chances are you'll get it to reflect either the skydome, or the island correctly, but not both. The waveset reflects an environment map rendered from the center point of your object. It renders this envmap as though it were a sphere of <envradius> radius around the center point. So if the center of your sky-sphere and center of waveset are the same, and envradius is set to the radius of your sky-sphere, then it will reflect the skydome perfectly. (but things closer than envradius will look strange)

What you need to do is come up with the approximate setup where this sphere-envmap approximation works best.
