Can you do virtual staging for real estate with Substance 3D Stager?

For sure, you can do real estate staging using Stager, but it's not going to be a quick process so it's also not going to be cheap. You'll need to develop enough familiarity with Stager and, most likely, Painter, to build the kind of environments you want. Stager doesn't turn a photograph into a 3D scene, so you would need either a 3D model of each interior or you'd have to fake it using planes to catch shadows and to which you could apply materials for walls and floors.

I would expect to find more useful, easier-to-use service providers and render products tailored to exactly this market. They are likely to be more economical for most purposes.

Hi, can you give us more infos? But only with Stager no, as i know but something could be with Aero but i need to test if it works. 
Do you mean just changin colors or changing, for example, a chir by sofa or something like that?
