So I went out the other day and shot some brand new images that I made into seamless textures...they live on these pages on my site:
TXR - BRICK - Seamless
soundimage.org/txr-brick-seamless
TXR - ORGANIC
soundimage.org/txr-organic
TXR - ROCK/STONE - Seamless
soundimage.org/txr-rockstone-seamless
As always, they're 100% free to use with attribution, like my thousands of other images and music tracks.
Speaking of which, please don't forget to check out my Ogg music packs. These packs enable you to bulk-download all of my music at once from various genres...hundreds of tracks. I even have a "mega pack" that contains all of my game music...over 1100 tracks.
Besides being a huge time-saver, the Ogg versions of my tracks loop really well in game engines...(Mp3 files sometimes need editing due to the Mp3 encoding process.) Plus, Ogg encoding sounds richer and fuller....almost as good as my original WAV recordings.
Anyhow, here are links to the packs:

Enjoy, stay safe and keep being creative! :-)
