import and export fbx at the runtime

Hi
i want to import and export fbx at the runtime
please help me
thanks

 

There's no built-in support for runtime loading of FBX files. You'd have to write your own loader or depend on asset bundles.

 

ok if there is no package for import fbx at the runtime , what is your suggested way to load the "terrain and lots of objects from hard disk" at runtime?

 

there's many free fbx importer/exports (and asset store has some paid ones too i guess).

have some list of importer/exporters here https://github.com/UnityCommunity/CADImportExport/issues/1

asset bundles would be probably best bet (since they contain unity components, materials, colliders etc)..
but the problem is that they need to be authored inside unity. (to generate asset bundles)

for terrain can load heightmap as a texture, and other texture maps for splatmaps, treemaps etc.

 

Are the fbx

thanks for your reply
1-are importers you mentioned working at the runtime?!
2-how can load heightmap to form of terrain with texture?
3-for other objects how can load them with textures at the runtime? if i load them to form of OBJ then texture of them is problem ...

 

1) probably not all of those, haven't tested (and some are quite old, that list only contains those found in github, asset store has more)
2) if its unity terrain, then something like this https://answers.unity.com/questions/1241166/raw-file-heightmap-switch-at-runtime.html *note that is quite old post, things might have changed.. but search for runtime terrain heightmap
if its custom mesh terrain, then not really applicable to that
3) basic textures do work from obj, fbx (with asset bundles you'd probably have more control of advanced textures and shaders, with obj/fbx you'd need to assign special shaders / their properties after importing)

 

yes my terrain is custom mesh (Made by 3D-Max)

 

i read all of your weblog , thanks , that is good
i searched about import fbx at the runtime... but not found any solution

 

theres few here,

This is the stupidest thing I've ever seen in my life. How can you call yourself a 3D engine and not even be able to load an FBX file? Why would they make you jump through hoops to load something every game on the planet needs to load? Maybe I'm ignorant, but that's like not having a simple way to load a text file in a word processing program. WHAT?!

 

If you add the fbx to your Unity project then you can load it without problems in the runtime. This is only a problem when you want to load fbx file that are not already in your Unity project.

 

I made one called RuntimeFbx Lite, you can try it. Static Mesh loading and saving functions are partially ready; SkinnedMeshRenderer support is being implemented and will be available in RuntimeFbx Pro.

Thank you for sharing the amazing asset! Runtime FBX loading is what I am looking for my project!

And #10 I know your reply is about a year ago, but what you're doing is: saying somebody is stupid when you couldn't understand the problem is not simple at all.
