Access HDR data of CubeMap; Has RGBM support been completely removed from Unity?
I developed a tool to extract CubeMaps with the convoluted mipmaps for editing in Photoshop back when Unity was still using RGBM encoding Unity 5.4.4 and before.
When Unity changed to using half float CubeMaps in 5.5 I lost the ability to extract the information. cubemap.getpixels is the only available option. With RGBM I was getting all of the data I needed to reconstruct the maps. Now though cubemap.getpixels obviously returns a 24bit RGB value and I can not get the float value being stored which would require cubemap.getpixels33 which has not been implemented in the C# class.
It appears that RGBM workflow has been removed as the importer functions. They are now obsolete not just depreciated.
Does anyone know I might get access to the HDR cubemaps being stored in the most recent versions of Unity maybe with reflection or a shader?
