For an upcoming shoot I need to create a classroom set, but I don't have access to the school tables I need to create the desired effect; instead, I was thinking about filming with simply IKEA tables painted in blue/with tracking markers and replacing with a 3D model. I've never tried anything like this before, nor do I have PP/AE (I mostly use Hitfilm basic and Blender, + Fusion 360 for 3D modelling (my only paid software)), but I need the actors to interact with the table, placing objects on it, etc. so I can't just superimpose the model over a blank plate.
I'm mostly trying to find the most fail-safe way over necessarily the easiest, although I don't exactly want to spend much money, hence why the chroma key solution looks appealing. The end goal is to map the model onto the real table (which is of the same shape), not to use chroma key necessarily.
I was wondering if anyone has any experience with this sort of thing, and if so, I'd like to hear any potential pitfalls or advice about full-scale object replacement of this form (maybe chroma key is not the simplest method?). Advice on lighting the complex shape sufficiently, or placement of tracking markers, is also appreciated.
