I have a floor tile texture I want to use in my bathroom Sketchup/Unity model (Its a photo I've taken of the actual tile).
I have tried these two tutorials and none of them reduces the uneven brightness and they also remove alot of detail from the texture
This is my texture
If i offset the image you can clearly see the problem
Do you guys have any ideas on how to attack the problem?
I found this tutorial, http://www.gamasutra.com/view/feature/131482/the_power_of_the_high_pass_filter.php
And I experimented some more with high pass filter only, I got this result which im pretty happy with
Looks like this in Unity (Needs alot of work on lighting)
Update: I tried Keavon's method when I was working on this, revisted the method and got this result. below is the high pass filter method for comparison
