This model trained on WoW maps, so it can produce maps in Warcraft-like style. I didn't tag dataset so, it may be not as flexible as it should be, but maybe one day i will tag it for v2.
For automatic1111 (and Forge) i can recommend this workflow:
Sampler: any
Steps: 25-40
Resolution: any XL-compatible (1024x768, 1216x832, 1024x1024, etc.)
Hi-Res: x1.25-x1.5 with 8x_NMKD-Superscale_150000_G for grainy texture or with R-ESRGAN 4x+ Anime6B for flat look without artifacts.
Hi-res steps: 10-15
Denoise: 0.2-0.3
Also i do not recommend vanilla SDXL, so you may use something like SDXL Nuclear or Zavy Chroma XL (or any your favorite XL checkpoint).
