I convert the .fbx model to .h and render and object but i want to know if i can render .fbx with vuforia native. 

Hello notassignedname,

This is certainly possible, but Vuforia does not provide any APIs for rendering fbx files in Android Studio. You'll need to look elsewhere for a library that can do this for you, or write one yourself. Once you're able to render it you can associate it with custom Image Targets in Vuforia.

Thanks,
