I have that one on my todo list, but my suspicion is that it's going to be a very tough one. The lightfields are rather computation-heavy on the vertex shader side (all the geometry relative to the sun needs to be done) and on my machine scale with vertex count. Now, random vegetation seems to increase vertex count a lot, and this may well be not doable by just taking the code and applying it to the vegetation (it didn't work with clouds either). So it probably needs a dedicated approximation scheme making use of the fact that vegetation is drawn relatively close to the position and not 100 km distant to run at all. Given my framerate when switching on lightfields and random vegetation without lightfield shading, I'm not too optimistic :-( But worth a try. * Thorsten ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
