DX9 vs. DX11 texture coordinates and transforms mystery

Hi All in general and vux in particular

these days I am working with DX11 and among other things trying to convert @mrboni))'s nice dome camera: ((forum:dome-master-full-dome to DX11 but it is giving me quite some trouble.

I was in the naive impression that as long as I gave the same .x-file, the same texture and the same transforms it would look the same…

as far as I can tell, the DX9 and DX11 renderers in the attached patch should look the same but they don’t.

am I right or wrong please enlighten me.
