Hello everyone !
I have an issue with an animation came from an FBX file. I made the animation in 24 FPS but Sketchfab displays it in a weird way :
First, it displays 375 frames whereas my animation stands on 300 frames (301 withe the “0”). Sketchfab informs that it displays it in 30 FPS…
When my fan is turned on, it accelerates and the mesh is replaced by a blurred one. If I switch the SketchFab viewer from frames to seconds, a stupid animation is noticeable between this two steps : You can see the first helix being downsized and the blurred one being up-sized. These two transformations are meant to be invisible because the change takes just one frame. With the viewer set in “frames mode”, this glitch doesn’t appear.
The FBX doesn’t seem to carry the information that my animation is a 24FPS one. On 3DS Max, I have to import it in a 24FPS scene to obtain a good result. If I just double-click on the FBX to open it with 3DS Max, It will load a 30FPS scene with more than 300 frames. So, maybe it’s an export problem, but after some tests, I think that the truth is elsewhere…
Is there a way to advise Sketchfab that the animation is a 24FPS one ? Do I do something wrong with the export ?
