Hello, I am working on an animation downloaded from Keleb's Code Corner : free lowpoly 3D models that says there are 15 frames of animation included to open/close the box, however after importing into the unity project, I don’t see them. Can anyone point out this treasure chest animation?
You can’t, as I’ve told you in the IRC, you can only import what is checked on this list. As you can see, for .3ds files only the mesh is supported, though luckily the texture is included seperately in the .zip so you can use that as well. The animation is not included seperately, so you cannot use it.
You could consider converting the .3ds to a .fbx using a converter. I have no experience with this though.
