Help with understanding floorplan concepts

So I just have a few questions trying to wrap my head around how floorplans work and are created.

Are effects such as lighting effects and any other effects or animations done in the initial floorplan creation? eg, in SweetHome3D? Or are these done afterwards in Gimp or a graphics editor?

Also, for each lighting effect, does it need to be a whole new image? What if I have like 20 different lights? Do I need to take a different screenshot for each light being on and off?

If I use the 3dcard for my floorplan, again im guessing all animations have to be done in the initial creation of the floorplan as this use the direct OBJ file for rendering. How can you add lighting effects.

I have a row of 8 lights I want to all turn on when turn on the entity.

Thanks

Hi Dean, is your final intent to use the 3D view that you can move/rotate/zoom within HA or are you looking to create a static image with light effects?

If as you said you are using the 3D card with OBJ file, I can’t help, I did the same as you but as well I do not know how to make lights interactive.
If you just want the static render of your house being interactive with lights effect then it is quite easier to me.

Honestly at this stage I will just at with both.

But I definitely want a static image with effects.

Cheers
