I've been searching the net for hours to find some good quality dungeon tiles, glad to see some real talent!
The background is way blurrier than the cracks, making it seem like old stone, while the cracks seem brand new. As you say its becaused the work was saved in jpg format.
FYI, even when set at 100% quality, jpeg is WAY less detailed than a true image and it shows, because jpeg essentially always divides images into color gradient 8x8 cells. So in terms of needed oversampling even at 100% quality jpeg you need 300 or 600 pixels to get 75 actual pixels actual detail resolution. Without oversampling this means that on a good printer or screen, this shows. The 2400x1200 source image isn't really needed because the amount of detail is actually 300x150. I tend to avoid jpeg like the plague for any finely detailed image, like a texture.
Still, great work. Thanks!
I worked with Genetica for a while, and eventually after 100+ hours 9ouch) I produced this for my project:
Which looks too much like "brand new dwarven royal hall" rather than decrepit dungeon, but hey for a guy with 0 talent in actual real drawing its a start. Genetica is very good for raw texturing, but for the "corridor setup" would need a real 3D program...
