how about u guys who know how to do textures,give us newbies some tips&tricks,or tex.creation tut links,because theyre so hard to find,grrrr...ANY help is welcome!!!=

I assume you''re talking about how to make seamless textures in particular. Well, one of the traditional techniques is to start with a texture you like, either from a photograph or by doing an image search on Google. Then, you use the offset filter (available in most photo-editing packages) to slide the unsightly seams to the center of the image. Finally, you hide the seams by using clone-stamp, blur, and other tools.

A tutorial illustrating this technique can be found here.

this was my mistake,sorry..i should be more specific as usual..
so tthis is the point:
seams are not problem,but i dont know how ppl paint tex. in 2d apps(and new ones...)
i alway model things in 3d modeling tools,aply material,screenshot it and then edit it in 2d program(paintshop pro)...im askin can tex(4example wall texs-bricks(4example)) be created only in 2d programs...(like photoshop)
btw.is genetica commercial project?is it just program to convert images into seamless images or is it texture creation program like tex.creator...

Making textures from scratch can be quite difficult, which is precisely why we started developing Genetica. Yes, Genetica is a commercial project, and will be available this summer. Genetica makes new textures from scratch, rather than making existing textures seamless. All the textures in the gallery (see blue link below) were created completely in Genetica. Textures made in Genetica automatically tile.
