chromebird Posted December 30, 2010 Posted December 30, 2010 Import of downscaled heightmap texture for occluder terrain causes editor crash: unsupported 16 bits compression. Heightmap was exported from Unigine editor to psd. Exported image was only downscaled in Photoshop, no other changes applied. If I change image to 8 bits per channel crash on import does not occur, but I have a suspicion that the image significantly loses its accuracy.
ulf.schroeter Posted December 30, 2010 Posted December 30, 2010 unsupported 16 bits compression. UNIGINE psd import currently only supports compression for 8 bits file formats. Also all input image formats will be internally converted by WorldOccluderTerrain to RGB8 image format, so providing 16 bit image input will not give a higher occlusion precision. Simply provide an R8 or RGB8 grayscale heightmap input image If I change image to 8 bits per channel crash on import does not occur, but I have a suspicion that the image significantly loses its accuracy. As occlusion testing always has to be conservative, reduced 8 bit height precision should be no problem (especially as occluder heightmap is also downscaled in x/y direction).
