Whenever you render any texture with any other application, the end result will 
be different. Simply put, the other application don't have the same algorythm to 
generate it's textures.

You can create a very simple test scene with 2, 3 or 4 box and apply your 
textures to those boxes. Such a test scene renders prety quickly and allow you 
to compare several textures side by side. That's usualy the technic I use.

There are other applications that enable you to do texture tweaking, but the end 
result can't be guaranteed in all cases. You can only be confident about the 
result if you use plain pigments. Anytime you have any reflection or 
transparency, the end result will depend on the environment.
