How to add an element to a moving 3-d model?
This is likely my VFX / editing inexperience showing..... but this is driving me crazy. I'm using last Pro 11 version at the moment (due to ongoing project work and not wanting to 'change horses in the middle of the stream') although I have a pre-extended license for new versions thru 2021.
I have a 3-d model in a clip that is 'animated' in the clip to move in the simulated 3-d space relative to the camera to then look like it is moving in the simulated world. Part way thru the clip, I need to have a spot on the model "change appearance". I have a texture ready to apply to that model at that point. At the same point I also have a Hitfilm Pro 3-d effect appear that this model appearance change has to appear underneath (effect is smoke stuff... so the texture sandwiched between the model and the smoke effect will show somewhat.
Normally I am familiar with tracking and can do that most of the time for what I need .... but I find I can't apply tracking to a 3-D model or a control point layer that controls that model. I've tried hand tracking the spot with the texture, but there is enough "jitter" in that (no matter how carefully I try) to be unrealistic. I know that I can get a far better "tie" to the desired location with a 2 point "track". IF I could track it.
So... any suggestions on how to do this?
Otherwise, I'm going to go modify the model file's textures and import a second model and change THAT out at the point the change has to happen. Maybe that IS the easiest solution.
