Hello

I am new since Friday to SweetHome3D.
It is amazing software - very impressive.

I am doing my first few renders of my designed home.

Questions:

1. In viewpoint mode - you can change the opacity of walls - it is a very neat feature. If I have an opacity set for 50% - is it possible to render a png with this opacity setting. If so, please can you explain how.

2. Is it possible to render a png with a transparent sky and transparent ground.

3. When in 3D mode - I can rotate/pan and zoom in/out around a fixed point, is it possible to move left, right, up or down so I can center my home to the middle of the screen.

3b. I believe another way would be to move everything to x:0, y:0 - is it possible to move 3 levels all with rooms, walls, furniture in one go?

4. I watched a youtube video; the guy had a search bar on his furniture navigator window (left of the screen) - mine does not? How did he do this?

Thank you.
Chris
