Environment background scale problem in MaxScript

[Anonymous]

Hi Everyone,

I have a MaxScript problem (in 3DS max 2017), where the background keeps getting resized.  I’m simply trying to render a foreground object composited against the viewport background (a bitmap).  In the MaxScript script example shown below, the background is this bitmap:

The foreground object is 3D model of a horse (read from a .OBJ file).  I want the horse to be rendered against the meadow with no change in the background.  Instead, the background keeps getting resized like this:

I am mindful that this problem may be because the Environment Map is set to some value other than ‘screen’.  I tried to set the Environment Map to ‘screen’ manually in 3DS Max as described here:

The manual setting itself seems to go fine, but when I run the MaxScript script, the background keeps getting resized.  On the other hand, I was not able to find any way of setting the Environment Map value to 'screen' within MaxScript itself.

Can someone please help?

Thank you very much,

Jay

Oh well, here you go:

environmentMap.coordinates.mappingType = 1
environmentMap.coordinates.mapping = 3
