How to Load external files (.fbx) at runtime?
Hi and thanks in advance for the help. I'm completely new to Unity. I have gotten in to Unity for HoloLense development. I am using Unity to graphically render fbx files. I want the end user to be able to navigate the file system of the HoloLense and select an FBX file, and have this file rendered so that the user can interact with it.
Is this a possible goal with Unity? If so, how is it done? Please let me know if the question needs more definition.
There are several assets on the store, and IIRC at least one that is free, there should be a forum thread for it.
You parse the file and build a mesh from the data. This isn't trivial as it requires figuring out the fbx specs and dealing with text and binary file versions, as well as a good understanding of how meshes are built in Unity (plus dealing with animation if you want to support that). I've seen an asset on the store that does this, which would save a large amount of time. .obj files are easier and there are more assets which import those.
i would recommend taking a look into https://www.autodesk.com/developer-network/platform-technologies/fbx-sdk-2019-0 the fbx sdk and working with a native plugin to load and pass the interpreted data to Unity
