I was been modeling and animating a simple model, i use an armature to make the animations. When i finish i tried to export the model to the .x format, but when i play it in the DirectX viewer it only show the selected key frame when the i make the export.
It’s pretty tricky getting animations to export to .X. You need to make sure everything is compatible, not doing anything that DirectX can’t, which there is a lot of in Blender.
What is your target application? You might have better luck with fbx, collada or another format if your target app can import it.
I don’t think the DirectX exporter can handle constraints, but fbx can, exporting the results correctly. For DirectX you’d have to apply them (I’m not sure how, but you can).
