Thanks Wolna,
No problem.
I learned it by experimenting in photoshop and lots of trial and error. I discovered most of my current techniques after I had already done about 2000 textures, and was ~80% finished with my Castlevania LOD pack (first version v1.1).
That's why I started re-doing my CLOD pack again from the beginning, so I could apply my "new" techniques throughout the whole game. It is quite an undertaking to do the whole game again but I am very happy to do it.
I like the techniques I use because it keeps the original look of the game as true as possible while still producing incredible results. As you can see it requires quite a bit of custom hand work to "fix up" the original textures and get a good finished look and I have a great sense of pride for every texture that comes out looking great.
New tip: In the video above: The use of taking a line from one of the layers and using it to make the "grout lines" between the tiles was something new for me. It was the first time I did that. Most textures (for CLOD) do not have such straight lines. So here is the tip for more irregular textures:
Create a new layer (Shift/Ctrl-N) above the "original" texture layer and use the paint brush with the color "black" to touch up the original textures by hand. (Try using Gaussian blur on this type of hand work as well
It's how I make soft detail for thing like character faces and other soft shadows)
Take a look at this .psd for an example:
CASTLEVANIA2#7823A168#2#0#B22E9B74_ciByRGBA - First Wall .psd
Another tip related to the .psd above: I make these .psd files all the time so I can:
1. Keep a backup with layers un-merged.
2. Make changes later on if I change my mind about the look or finish.
3. Use it as a convenient place to get the "hires" texture layers again for use with other textures that are related to it in game, especially if I did anything custom to them such as hue/saturation/brightness/contrast/photo filter/etc... changes to them for the particular "location" they are used in game.
Also, I have followed several photoshop tutorials I found on Google and that has taught me other techniques that I now use. Two of them are on how to make your own fire and lightning, and I am very proud of my work with those textures in my pack.
Later,
Jay
