The verdict
Spline is an excellent browser-based 3D design tool for interactive experiences and web-facing 3D content. It is not in any way focused on adult content. We include it here for creators who need interactive 3D environments (backdrops, UI elements, interactive product showcases) as a supplementary creative tool, not for character-based NSFW content.
Only relevant if you are building interactive 3D environments. For adult 3D character content, see Daz 3D or Honey Select 2.
Pros
- Browser-based — no install required
- Good AI design assistance for 3D layouts
- Free plan is functional
Cons
- Not adult content capable or focused
- Limited to design/environment use
- Irrelevant for character-based NSFW creation
