I’m hoping someone will be kind enough to help me even though this is my first post here. My expertise is with 3D Studio Max only using Combustion occasionally and always wishing I knew it better. After owning it for years I still find myself struggling whenever I attempt to do something out of the norm for me.
Currently I have animated an emitter in a trajectory pattern with an attached particle system. This has already been used to produce several animated clips with still backgrounds, but now I have a background footage that pans. I’ve tried deleting the animated trajectory and using tracking for the emitter with ‘Attach to Emitter’ both checked and unchecked. It just doesn’t produce the same effect. I read in the Help file that I could add the Particles Operator (with the existing animated trajectory) to a Layer and animate the layer to mimic the pan, but that creates another problem for me. How do a create an Alpha channel for the semi-transparent smoke particles or can I attach the Particles Operator to a layer with a transparent background?
Hmm. Was my 1st post a little too wordy or does everybody know I have a humpback, no neck and hair on my thumbs?
How ’bout this… Is it a no-no to place particles on a different layer than the layer containing the background footage? If not what must I do for the ‘shoot smoke’ particle (from the library) to look just a good as if it were on the same layer as the background footage? I’ve tried various keying methods with limited success.
