Some initial notes:
I describe a process I use, using the tools that I am accostomed to using. You may choose to use different tools, but for simplicity I will refer to the ones I use.
Some Basic Things:
When making tilable textures, it is desirable to keep things fairly uniform, as far as tone.
If it isn’t, you will find out when you test it
Learn this in GIMP: Image>>Transform>>Offset
–or in photoshop: Filters>>other>>offset
Blender can be very useful in starting to make your tile, not only in making the background
, but also for making any objects within the tile
If you have a crappy texture, make it into a good texture
The tools I use and what I use them for:
GIMP for setting the offset
Photoshop rubber stamp tool, for patching the seam
Various paint programs that have various cool tools, including Pixia, Photoshop, Gimp, Jasc Paintshop, and Corel Procreate painter, that came with my Wacom tablet, which I use all the time.
Blender for making background textures to start with, and any objects that are in the tile frame.
Basically how I make a tile
start with either a clean slate or an image for a base, depending, on what you are making, and what look you want to achieve.
change the offset in Photoshop or GIMP
go into photoshop, and use the rubber stamp tool to patch over the seam.
Make changes to the values, texture, basically change it in any way you want. Whatever you can dream up
Change the offset again in GIMP
Patch it once again, and test it out by tiling it in Blender
Here are some examples I made. Feel free to use them.
One question: Why don’t use the Stamp tool in the Gimp? Or the offset in Photoshop?
Painter is great (I don’t use it anymore, as i’m on Linux now). I have Painter 4 (also came with tablet). Did you know there is a feature to interactively do the offset thing? There is also a feature if you do a brush stroke over the image limits, the stroke appears on the opposite side again!
Don’t just look at the tip of your cursor when you’re painting,…sometimes you have to, but generally, try to take in the thing as a whole while you are moving your stylus around on the page. Trust your hand to do the job without your constant supervision. After all, when you see it in Blender, you are not looking at the individual pixels, but more the general shape and form of the texture. Hope that helps.
There are also several plugins for the gimp that in many cases I’ve found work very well.
homogenizer - smooths the brightness across the image
fixer - automates the basic tiling
resynthesizer - another automatic tiler, with more options and a different algorithm
All available for download at the gimp plugin registry.
For some textures you’ll have to touch them up, but for many I just get a patch of what I want for a texture, homogenize it (if necessary) and use the Fixer, Make Seamless Texture (standard plugin I think) or resynthesizer and I’m done.
Yep, I looked high and low for a high pass capability in the gimp and couldn’t find it. Finally stumbled on homogenizer and it generally works pretty well.
I’m not sure that the implementations have anything to do with each other though, but I only say that because I haven’t specifically seen homogenizer referred to as a high pass filter implementation. That very well may be all that it is.
just one thing for the german gimp users: The offset is located under: Bild -> Ebene -> Transformationen -> Offset but the shortkey <ctrl>-<shift>-o does work. (I searched for a while in “Bild”, so maybe you can avoid this)
Does anybody know where I can get compiled versions of these plug-ins for GIMP 2.0 for Windows? I tried compiling the source files but can’t get it to work right (and I am definitely not a programmer! )
Specifically, I am needing the Homogenizer plugin since there is no High-Pass Filter in the GIMP.
