quest3d.godbersen.eu 2013-07-29 HDR support, Manual updated, slight changes in respect to previous versions in pixel update conditions (see manual) Trial restrictions tightened 2012-10-17 Different Quest3D versions and 32/64 Bit machines require different dll's. Make sure you are copying the dll from the right subdirectory. Dll for 32 Bit Quest3D 5.0 on request only. Sample cgr's are written on different Quest3D Versions, which may not be backward compatible. For example, *500.cgr requires at least a 5.0 Editor version. SetTexturePixel versions for 4.3.2 and 5.0 differ due to major changes in the Quest3D architecture. The 5.0 version has been tested on Win7 and Win8 (X64), and the 4.3.2 on Win7. There is basically no size limit, if in doubt, try 2 squared sizes like 1024 x 1014
