One of the complaints that I usually get from people that want to create contents but unable to do so is “I do not know how to create 3d models”.
Here is my proposed solution, you can use 3D Models from SketchFab for your Unity + Vuforia AR. In this video I have made, you will learn to import Animated SketchFab 3D models straight into Unity for use with your Vuforia AR. This tutorial will work with most models that has simple animations. If you want to import a model with multiple animations, you need a different method
So, why is this sudden post? Err well, if you install the latest versions of Unity, you will notice that setting up Vuforia will be a little bit different. We will need to use Unity’s Package Manager. So to update this new knowledge, here’s the new tutorial for how to get started with Vuforia. From now on, I will be trying to use Camtasia Studio this time to easily explain things. Leave your comments on how you like it, and how I can improve

You will see two options. One is to install Unity only, second is to use Unity Hub. Download and install Unity Hub
Why Unity Hub?
Unity Hub allows you to manage and install addons and plugins easier. It will also help maintain multple versions of Unity. Why? Later on in your development life you will realise that unfortunately different people uses different versions of Unity for development. With the hub you can install their versions too, and access their project without screwing up your own project that uses your version of Unity
Installing the latest Unity in Unity Hub
Start up Unity Hub, you will see something like this. Press Add
Add Unity Version window appears, select the latest release of Unity and click Next

Its okay you now know all you need to know to do this. All you have to do is repeat these steps from “Let’s Start” to the end for each of your Image Target.
In the previous tutorial post, I have taught you how to publish a test app to Android. In this tutorial we will cover the topic that is a must for developer creating apps for Android, which is Publishing your Android App to Play Store.
This tutorial will be broken down to 7 parts. They are:
1 : Getting your app ready and publishing it as Android App Bundle (.aab)

4: Setting the Pricing and Distribution
5: Setting App Content description
6: Setting Store Listing
7: Final Steps and Publish!
Prerequisite
You need a few things in order to put your app to the Play Store. If you are not a graphics guy, you would need to ask a friend with such knowledge to help with the graphics part.
A privacy policy for your app. You can get one from https://www.websitepolicies.com/. Websitepolicies.com will provide you a public link to your policy. This is what you will need later.
