Step 15:
Save again. Be sure you're saving as
EntryWayWallsInner
NormalRaw
.
Why?
Since this strange bluish image makes it pretty tough to know what the
result will look like, it will be important to have the raw version to come
back to if the final result in Unity is not what was planned.
Step 16:
Flatten the image (Layer>Flatten Image).
Why?
We will need to “normalize” the image to bring the normal vectors back
into the needed value of 1, but this needs to be done to the total image
and not just one layer.
Step 17:
Normalize the image. Choose Filter>NVidia Tools>NormalMapFilter.
In the Alternate Conversion area check Normalize Only. Press OK.
Why?
The other settings can all remain the same because none of them will be
used. Normalize Only will ensure the red, green, and blue normal vectors
are exactly 1 and thus ready to be a normal map.
Step 18:
Save the image for use in Unity. Save the file as
EntryWay_
WallsInner_Normal
into the Incursion-Unity/Assets/EntryWay.fbm. The
file format can be whatever you'd like (I saved it as a .psd).
Why?
Due to our deft use of manual exporting, all the texture files related to the
EntryWay are in this EntryWay.fbm folder that Unity created. Adding any new
texture assets that are meant for EntryWay keeps the Project panel clean.
