You want to automatically generate batches of images and textures within Unreal Engine using only prompts to get what you want? The Infinite Texture Generator is the right tool for that.

Based on Stable Diffusion, it can either generate realistic images or tillable texture just with prompts.

The Editor module allows you to script the generation of dozens of textures; using CUDA and the GPU rendering capacities, it is extremely fast.

The Runtime module also allows you to generate images, but in runtime (note: unlike, the Editor module which relies on CUDA, the Runtime module uses CPU and is therefore a LOT slower).
