What size should we be using to generate babylon HDR using BABYLON.Tools.generateBabylonHDR ??? The cabman actual image resolution is 3200 x 1600 ... the cube face size is 2048... But if i try to pre-process a cabman at 2048 full resolution IT NEVER FINISHES ... over 12 hours still never finishes... Everywhere i see HDRCubeTexture is always using SOME MUCH LOWER (like 256 or 512) cube map size then the actual cabman face size. Is there some SCALE or RATIO we should using OR are we supposed to trying to run HDR at whatever the actual cabemap face size ???
The latest webgl 20 and vertex array object might need a bit of tweaking or the generateBabylonHDR functions do. the update cause more webgl error when using a pre processed HDR file produced using the generateBabylonHDROnDisk: [.Offscreen-For-WebGL-0x7f9edb812e00]GL ERROR :GL_INVALID_OPERATION : glTexImage2D: invalid internalformat/format/type combination 0x8814/0x1907/0x1406 196/#UTEVJ#0:1 [.Offscreen-For-WebGL-0x7f9edb812e00]RENDER WARNING: texture bound to texture unit 0 is not renderable.
