I want to make water caustics on BGE, but Its very hard to achieve this, I m trying to make a this for a lot of time and I reach nothing satictisfatory, can you guys help me to work this out, beucause Im kind of out of ideas to make it now!
well I think that I solved my problem miself, but if you guys are making something close to what I wanted and dont know how just visit this link: http://www.lysator.liu.se/~kand/caustics/CausticsGenerator_v1.4.zip there is a caustic generator, then with a little of gim or photoshop you ll be abble to create your own animated texture!
Might be possible with a shader? Chances are you’d have to bake caustics as a texture. If it’s for moving water you could use the video texture module so that you can animate them with the water motion.
