@3run @gri @Random: Hello again, because the OVERLAY flag works now i've sent the demo to you.
If your GPU is not nVidia, reduce the MAX_PARTICLES to 5000-10000 depends of your CPU.
The emiter, drain and form has no effect yet.
If you have kepler GPU, please use the both kepler files from KeplerPatch32 folder.
If you have problems, please send me the acklog.txt file, thanks!
Merry Christmas!
