Importing an .obj into Unity / Making normalmaps

I wrote this for Begoña but I thought I would post it here as well for reference in case anyone else needs to do this in the near future.

Here's a quick and rough guide to import Triton into Unity and attach a normalmap to it.

Importing an .obj into Unity

• Click and drag Triton folder into Assets box
• Set Triton GameObject to position X=0, Y=0, Z=0
• Place Triton prefab into scene and zoom out as it'll be pretty big
• The sphere will be black in colour for now
• Open the Triton GameObject in the Hierarchy (on the left, where the Main Camera is)
• Click on the pSphere1 object, this will be the actual black sphere object
• In the Inspector (on the right side) you'll see your texture (blinn1sG) in a Diffuse shader
• We need to change the Main Colour to a brighter one rather than black (Pick white for example).
• Now you should see a sphere with your texture on it, but you won't have any nice bumps on it
• We need to change this to use the bump mapping, so it looks nice
• Click on the shader that says Diffuse and change it to Bumped Diffuse
• Now you'll see a little empty grey box called Normalmap
• We need to convert our Bumpmap to a Normalmap to use with the shader

If you have your own normal map you can use that instead, if not see below: 

Converting a Bumpmap to a Normalmap in Unity:

• Go to Assets > YOURASSET > Click on your BumpMap image
• Change the Texture Type from Texture to Normal Map
• Here you can change options on how bumpy you want it and if you want it smooth or clamped etc. You can come back and change this whenever you like.
• Once done click Apply
• Your bump map will now be a Normalmap

Now that we have a normalmap we can apply it to pSphere1

• Click on pSphere1 again and drag your new Normalmap into the empty grey box

Now your object should have the normalmap applied and it'll look bumpy.
