Your favorite filters/programs for textures?

I use FilterForge to create textures for 3D models that i create in Blender, are there any other filters (Photoshop) or programs that i should look up? I still consider myself a newbie

My favorite programs so far are:

FilterForge
PixelPlant (to make seamless textures from anything)
RedField's iEmboss (PS filter, great for brining out depth, making clean textures dirtier)
CrazyBump

I'm sure there are many other programs out there just as good or better that i'm missing out on

A filter that i would like to have is something that can mix 2 or more textures together, like the blending options in PS but as a filter so you very quickly could browse though all different effects that could be possible.

I find that I pretty much don't use other pshop filters now that I use FF. (You can make something similar iEmboss in FF, for example.)

The one big exception to that, though, is Redfield Perfectum. It can take a nasty jpeg-ed image and make it all smooth and useful.

Zbrush is actually very useful as a texture making application, although most people don't use it that way. Check out: http://www.pixologic.com/zclassroom/homeroom/ and watch the video called 'Tileable textures/maps Keep in mind that you can drop any kind of 3d model into that, not just be limited to the sculpt tools.

take a look at genetica. i dont have it but a few here do.
