Well, I was looking for a 3D model, but none of the ones out there were quite doing it for me, so I made this merge with

MiaoMiao 3D Harem - NBXL-1.0 | Illustrious Checkpoint | Civitai

and

Nova 3DCG XL - Illustrious v3.0 | Illustrious Checkpoint | Civitai

You can use trigger words like 3D, render, blender, unreal engine, octane, realistic

I recommend using Euler a sampler

Works well with Loras like 3D Style for Illustrious - v4 | Illustrious LoRA | Civitai

and DAZ3D Style / 3D Rendering Hentai IL - v1.0 | Illustrious LoRA | Civitai
