Code:
I'm sorry, but an uncaught exception occurred.

• It used to be part of older 6.x/7.x builds (and even then was undocumented), but was removed/renamed during the rendering system overhaul.
• Your GenAI mod’s is calling it directly, so on 8.1.3 you get an AttributeError.
It's in the readme. Make sure your stable diffusion is working, it is as simple as placing the latest AI mod files into the game folder
Thank you so much for those answers. I read those many times before I posted. Here is what I have learned. 1. Buggy but works. 2. No instructions as to what models, lora, mixes, checkpoints are optimal (at least what I could find). There were a few random posts that offered options. 3. Super slow on my potato (GTX 1000 series)--not a surprise. 4. It seems optimal to have both the stable diffusion web interface and the game open while you are trying to find a good model. 5. All the usual challenges of getting full body images, consistent design, and non-abominations are here. 6. If you think that the initial pictures are hard to generate, wait until you get to the action ones. 7. If you are new to this don't be distracted by expert users that show you perfect pictures. It is a long road from here to there.
TL;DR If you already great using these tools, the installation for this game is trivially easy.

I will give you a huge boost to figuring out what checkpoints and loras will work best for you the fastest. Its actually something I do every time a checkpoint gets updated or I think one may work good.
1. Load up the game and mod and get it to generate a picture. Any will do.
2. Look in the GenAI settings and see how the positive prompt is built and what seed is being used. This is something you can copy or transcribe into a notepad file to use later.
3. Open the WebUI and put that prompt that was built in the positive and seed and you can pretty accurately generate a base image to test.
This lets you figure out generation times, add or remove LoRA, and see if you need to adjust the prompts for different things. I did this for a update to the Photorealistic All-Purpose checkpoint I use and it was 80% accurate on generation and down to 5-7 seconds with the dmd2_sdxl_4step_lora_fp16 added in.
Hope this helps and good luck baking your potato!

Thank you so much for this thoughtful information! I'm grateful to the developer for making this available; I'm just a bit behind on the hardware side. I'm certain that this AI approach is where most mainstream games will be in 10 years.
dumb question. How do you add loras and other items to every prompt, for instance dmd2_sdxl_4step_lora_fp16 ?

Since the GenAI version I am using reads from a separate prompt file I put general ones under the "style_prompt": line.
Example:
"style_prompt": "<lora:dmd2_sdxl_4step_lora_fp16:1>, lifestyle photography, full body, edge lighting, Leica M3, Fujicolor Pro, 80mm lens, photorealistic, bokeh, black background",
Do I need to download the base game and the mods, or can I just download the mods to play the game?
