How to export .dae animation from Blender?

阅读更多关于 How to export .dae animation from Blender?

问题 I was practicing animation in Blender so I downloaded a .dae file of a car and implemented some animation to it. I wanted to make the car open and close the door and I manage to do that (inserting keyframes to it). The problem is that when I export it to .dae File -> Export -> DAE and import it, to see if the animation was saved: File -> Import -> DAE but it doesn't do anything. Is there any way I can export and see the animation as .dae file?* P.S. I want it to export it as a .dae file

问题 I have an ARKit scene with an invisible SCNPlane : plane.geometry?.firstMaterial?.colorBufferWriteMask = [] This plane is placed on the ground and is used to render deferred shadows from other objects placed in the scene.
