I have recently subscribed to the full version of Wombo, and it has just had some game changing updates. You can now have various aspect ratios including a square one which can be used to generate textures. Also you can save them with no watermark, so they can be used in Nomad.
Here are a few I quickly knocked up.
They can be varied as Wombo saves the A.I. Data
Groundbreaking stuff and all generated just from words such as “eyeball texture” I usually use realistic mode.
