1. Misha is helping Kucheriavyi to solve the problem.
2. Yes, that's the main goal.
what we're trying to achieve is to get a realistic object and it's shadow in the same render, but for now I can't get it. The files, that I attached are the previous method, when the shadows and the objects where rendered separately and I combined them in Photoshop. The thing is, that the shadows are black and solid and aren't transperent, which is not realistic. To make them them realistic, I need to edit every single shadow in Photoshop, or After Effects, or whatever, but if I need to make 30 rooms, 5 such layered objects with shadows in each room - I need to work on 150 objects, and if I have to create 3 videos per room, 60 frames each, that means, that I need to edit 27 000 frames (or shadows of the objects). That's why I'm trying to find the way to get realistic transperent shadows instead of solid black, that I get for now. And I'm trying to find the way to render the shadows together with the objects.
The method, that is used in the video tutorial works well with the environment backplate, but I don't have such beckplate, my environment is a room. Also, that method works well in a simple environment, like 3 boxes and a teapot, but when I try to apply it in a room, I get unrealistic objects and unrealistic shadows.
The attachtments in the first post are the examples of how I worked previously, I wasn't able to add more in the same post. I'll attach the results that I got in a few next posts.
