No problem, you are welcome. It IS indeed a bit complicated, but from a programmers point of view it is very logical. Lights, switches, sound sources, build in furniture, Unity assets, additional persons, etc. are so called Atoms. You have to add one of those Atoms to a scene, select it and there you have all the options tabs. Custom Unity Assets were added to VaM relatively late in the development process. So it is only one of all those many different Atoms. VaM has a steep learning curve, but this is because it is a sandbox app. You have so much options and tools, you can almost create everything you want. Nevertheless, once it is ready for the mass market, it really needs a big facelifting.
