Kind of a noob question but what is the process for creating a custom background in VaM? For example, let's say I wanted a brick wall. I'm assuming it's not as easy as just importing a .jpg or .png image. Is it something I can create in Photoshop and if so what are the specs I need to follow and the output format? Or must it be created in a 3D program like DAZ or Blender? Any tutorials or videos on this?
