Change AutoCAD Render IBL settings through VBA

[reuter.philipp]

Hello,

I am trying to write a script for my company to set the render settings to the desired preset with one click. Almost everything works, but I can't find a way to select if the IBL background or a custom background is used. It is possible to create a view with a background using -VIEW, but then the IBL background is still visible during the render and not the one selected in the view.

Does anyone happen to know how to change the background via VBA without the selection window appearing and still be able to choose between the different background types?

With kind regards,

Philipp

It is about the following two popups that appear when you have activated IBL and enter "_BACKGROUND":

 

 

Or another way to set a transparent render background.
