Are there any easy ways to achieve what might be classified as weather type effects like, rain, snow, rainbow, lightning, smoke etc? If there aren't plugins already available can one make them using other programs like Cool 3D,or other graphic programs?
I have managed to re-create a snowfall of sorts from within Vegas using a black backround, add noise filter, a bit of tweaking, keyframing movement, and masking over the vid. ( The Veg is posted on the veg sharing site on Sundancemediagroup.com, though you will probably have to work on it a bit to make it more realistic...).
A good programme to check out is AlamDv for lightning, fog etc using specific plugins (see Alamdv.com...)
