How do I create textures for my UDK maps? Thread

Hello again, so I realized a problem I have in level design is I rely on already made materials and static meshes. So I want to take the steps needed to learn how to create all custom content.

I used a camera I have to try taking pictures of things like tiles or walls and editing them to work as textures but I found it really hard to make them even in photoshop, maybe it's my poor photoshop skills but I started thinking that's not how the pro's do it.

I am familiar with the material editor, so I really just want to learn now how to create textures. For say, terrain, walls, tiles, water, etc.
Could someone maybe point me towards the program I need to use and some tutorials? Or maybe there are different methods?

you already have the program that you need. photoshop (or some equivalent software) is 90% of texturing.
Pros use photoshop just as much, though they often don't have to worry about normal maps and AO since creating them is often modeler's task.

for tutorials, try these:
Philipk.net
Katsbits.com

Still, texturing isn't a skill you can learn in few days, just like you can't become a good level designer in few days. Practice is necessary to achieve good results.
