Relevance of bounding box info in *.sd files

[Hannes44]

Is the ESD_bounding_box info in the *.sd file of scenery objects of any importance for OR?

I don't think so? Check out these two threads at ET, perhaps a developer ( or someone with direct knowledge of the code) will see your post and reply.

If you want to make the object snapable it's required. I recall also that OR uses the BB to keep rain/snow out of the inside of buildings.

Thanks for the information, my conclusion, ESD_bounding_box is not required for only decorative scenery objects

Vince, that's interesting, I wondered how that was accomplished.

Hi Gerry,

It was enabled in default MSRE & uses the 'X' key to toggle. There is no indication if 'snap' is on or off.
One of the default shapes is WireFence50m.s
Here's the Shape Data (SD) file for the default fence. I found out about thias feature accidentally and wrote it up in the forums several years ago.

SIMISA@@@@@@@@@@JINX0t1t______

shape ( WireFence50m.s
	ESD_Detail_Level ( 9 )
	ESD_Alternative_Texture ( 1 )
	ESD_Bounding_Box ( -25 0 0 25 1.5 0 )
	ESD_No_Visual_Obstruction ()
	ESD_Snapable   ( )
)

Any static object can be made 'snapable' by entering the proper parameters in the SD file. Easy to do.
So it's the data in the SD file that 'snaps' together not anything to do with the shape file itself.

The SD file ESD_Bounding_Box parameter does not need to conform to the actual shape.
For instance, in the LIRR route I set the 'snap' feature to work with the de_OldStation platform objects but there was a problem with the platform station house part. It's pivot point was offset from the other platform sections and thus I had to offset the BB for tat particular part.

They're in the LIRR at many of the stations, the ones with the brown colored platform surfaces if you want to have a look at the way the SD files BB's are set up.

regards,
