Hello ISI, Not sure whether this is a correct Sub-forum for my question, please move it to proper section if applies. All ANM files seems to contain pre-computed per-frame animation, and 3dsMax export with different "Get Frames From" settings give no difference. Looks like it was intended to support "Key frame" animation export (with real-time frames interpolation on game engine), but ANM are always saved in mode "Interval" framing each 1/FPS second. So, the question: does game engine support key-frame interpolation, or it requires ANM files to contain precomputed per-frame data to be saved? output ANM files (driver steering) are usually appears to be about 1-2Mb size) while these could be 50-100kb for almost no cost. Just curious. Regards, Oleg.
