I wanted to redesign our living room interior to make it more comfortable to host our friends and family. Of course, we can make the process better with software.
Sweet Home 3D is a free interior design application that helps you draw the plan of your house, arrange furniture on it and visit the results in 3D.
I measured every wall in our house to create the floor plan. Next, I brought in 3D models from the included library and the internet (sketchfab is a good place to start).
The UI is a bit old school, but it's richly featured, so whatever you're looking for is there.
Sweet Home has a render option that lets you get higher quality images with better lighting, and the results are... okay.
We can do better though. So we export the whole house with 3D view > Export to OBJ format. Next, import the .obj file in Blender, add some lights, adjust render settings and you get a much higher quality render.
