Missler was kind enough to send me a link to the
ATI CubeMapGen which makes creating a CubeMap Environment for TopSolid 7 a piece of cake!
I can´t belive i missed this one, it makes things alot easier working with CubeMaps!
Just open up your “CubeCross” (that you created in “HDR Shop”) in CubeMapGen, choose “Save CubeMap (.dds)” and that´s it. You´re done!
Note: CubeMapGen also functions as an HDRShop plugin that provides the filtering functionality of CubeMapGen to HDRShop v1.0.
