[Closed] convert hdri to exr through max

Hi,

I try to convert hdri to exr through max. Unfourtunately it will convert into ldr image even with the hdr switch set true. Maybe it opens it already as an ldr. Is it possible to open it as hdr? Thanks!

mapfile = openBitmap rendercamerasettings.envpath.text 
newexr = bitmap mapfile.width mapfile.height hdr:true
newexr.filename = (out_path + "enviroment.exr")
copy mapfile newexr
save newexr
close newexr
