oh I added the dust particles and they looked just perfect, but when I converted to mdx, boom!, now the particles length are changed by width, and this is pissing me off, because every particle got like this, even in-game, when I opened the model in magos. Is magos that bugged or the mistake is mine? I mean, in max5 it looks good, but, if I open it as mdx in magos, I have to restart the computer so the particles get back to normal...!
