Hi, the general idea is to use postwork, that is what they do in movies. Almost all softwares can have problems loading many instances for Vic ou Mic, because the polygon count and size of textures.

My workflow when I have problems importing a lot of figures is to divide my scene in planes:

1 - background - the most back par tof the scene, that dont receive shadows or reflections from characters, like trees, house or mountais.

2 - middle plane: where people are, in general I render the people separeted in groups and add to the scene later, or as a postwork in Photoshop or using alpha planes to fake their position in the scene (good to have ground reflections)

 

3 - first plane: the most important part of the scene, even with people around.

 

After that I can join all inside Carrara with alpha planes (as splats) and using a good camera position, or inside Photoshop or another editor. I really like to use FXHome Composit lab Pro, its a toll for video that really works with illustration too.
