How to create textures?

[biomanz]

I haven't been able to find any tutorials or videos on how to come up textures such as this one from Blizzard. Most notably all the grit on the bottom ornaments/weapons, and the dragon bone textures. This might not have been drawn with Photoshop, but I've seen stuff like this being done with just that, so can anyone describe how it is mostly or most likely done? I'm guessing it's all about different brushes, some photograph overlaying, and layer settings, along with tens of hours of detailing with basic brushes?

I just want to stop asking myself "How the HECK do they texture THAT?!" everytime I see nice things!

In Photoshop check the Texture tab.

You can install Adobe photoshop on your computer after you have verified its compatibility with your operating system.Also be sure you have adequate memory and storage space.Using CS3 and was wondering where you got your starburst shape from.I don't have one like yours'Thanks.
