Techno’s Timeless is a very simplistic texture pack. It looks especially good for modern architecture, e.g. cities, and other areas which you want to look sharp and clean. Even though the design looks really simple it’s detailed enough to create an fun and interesting environment in Minecraft.
Even though we (MCPE DL) fixed most of the missing textures for the original port there may still be blocks or mobs which aren’t ported yet.
