- If parallax shader is enabled (look here for the details [http://cs.elderscrolls.com/constwiki/index.php/Enable_or_Disable_Parallax_shader_on_meshes lnk]), the alpha channel greyscale act as a heightmap for the parallax shader (Black: the pixel is carved, white: the pixel is popping out). Choose DXT3 or DXT5 (recommended the latter). | - If parallax shader is enabled (look here for the details [http://cs.elderscrolls.com/constwiki/index.php/Enable_or_Disable_Parallax_shader_on_meshes lnk]), the alpha channel greyscale act as a heightmap for the parallax shader (Black: the pixel is carved, white: the pixel is popping out, 50% gray, the pixel is at baseline).
