+This tutorial will show you how to make your first VR model.
+For the sake of this tutorial we will be editing the right hand model.
+
+:::tip
+This tutorial makes use of the program [Blender](https://www.blender.org/download/), make sure you have it before following this tutorial.
+:::
+
+## Viewing the model in Blender
+
+First you need to import the model into Blender:
+
+![](/assets/images/vr/tutorial-hand-right/import-1.png)
+![](/assets/images/vr/tutorial-hand-right/import-2.png)
+![](/assets/images/vr/tutorial-hand-right/import-3.png)
+
+Your model is now imported but it misses a texture.
+To add a texture you will go to the Shading tab in blender.
+There you are going to add a texture element like this:
+
+![](/assets/images/vr/tutorial-hand-right/shading-add-texture-element.png)
+![](/assets/images/vr/tutorial-hand-right/texture-element.png)
+
+In that element you press open and select your texture in our case it is `something\VRpackTemplate\textures\hologram_hands.png`.
+Make sure you change linear to closest, otherwise your texture will look blurry.
+In the end it will look like this:
+
+![](/assets/images/vr/tutorial-hand-right/texture-element-complete.png)
+
+Now its time to add the texture to the models material.
+You hold the yellow dot and connect it to the other yellow dot like this:
+
+![](/assets/images/vr/tutorial-hand-right/texture-base-connect.png)
+
+If everything went good your model should now look like this:
+
+![](/assets/images/vr/tutorial-hand-right/texture-on-model.png)
+
+## Editing the model
+
+With editing the model you have almost total freedom, the only requirement is that the model only uses 1 texture.
+
+### Editing the model (easy)
+
+Since this is the easy tutorial, we will show you how to make the hand into an arm.
+
+First we need to figure out the dimensions of this object.
+
+![](/assets/images/vr/tutorial-hand-right/model-dimensions.png)
+
+This image shows us that 3 pixels is equivalent to 18.75 meters in Blender, an arm is 12 pixels long so this means an arm is `4 * 18.75 = 75 meters` in Blender.
+When editing the dimensions it will look like this:
+
+![](/assets/images/vr/tutorial-hand-right/edited-dimensions-1.png)
+
+If we import it into minecraft the arm will be to far away. This is because the original model is made for a hand not an arm. So we need to move it `3 * 18.75 = 56.25 meters` down.
+

+
+#### Texturing
+
+Since this is an arm we will use the steve arm model, you import it the same way like we did above.
+
+![](/assets/images/vr/tutorial-hand-right/hologram-hands-steve.png)
+
+![](/assets/images/vr/tutorial-hand-right/steve-texture-stretched.png)
+
+Now you might notice your texture is stretched out. to fix this we will go to UV-editing and edit the uv map.
+UV-editing looks almost the same to blockbench.
+
+![](/assets/images/vr/tutorial-hand-right/uv-map.png)
+
+:::tip
+Its handy to turn on this magnet looking icon so its more precise.
+![](/assets/images/vr/tutorial-hand-right/magnet-icon.png)
+:::
+
+We start with selecting the top and the bottom of the hand.
+
+![](/assets/images/vr/tutorial-hand-right/uv-map-top-selected.png)
+
+Next we select the move tool.
+
+![](/assets/images/vr/tutorial-hand-right/uv-map-pos.png)
+
+Now we move the top face and bottom face to the top of the texture.
+
+![](/assets/images/vr/tutorial-hand-right/uv-map-top-move-up.png)
+
+The same for the sides of the arm.
+
+Your new uv map should look something like this:
+
+![](/assets/images/vr/tutorial-hand-right/uv-map-side-up.png)
+
+If we look how the arm look we see all is now fixed.
+
+![](/assets/images/vr/tutorial-hand-right/uv-map-done.png)
+
+#### Export it!
+
+It is time to now export your model first put the steve arm texture inside `VRpackTemplateRP\textures`.
+Call it `hologram_hands.png`.
+
+![](/assets/images/vr/tutorial-hand-right/export-texture.png)
+
+Now lets export the model.
+
+![](/assets/images/vr/tutorial-hand-right/export-model-1.png)
+
+Call the model `hologram_hand_right.obj`.
+
+![](/assets/images/vr/tutorial-hand-right/export-model-2.png)
+
+#### Testing it in game
+
+Load the pack into minecraft and try it out if it looks like this you succeeded in this tutorial!
