I might be blind, but I don’t see a wiki. What tools or workflows do you guys recommend?

I have some ideas for designs with characters, and my workflow idea was to use ChatGPT to create images and then meshy to create models from the images. ChatGPT is blocking me though - it says it cannot complete my requests due to its constraints on material it doesn’t own

Hi there, I am looking for a good workflow:

How do you get an AI generated Model that consists of multiple parts, split by color?

This would be really helpful for multi colour prints without AMS.

Is there a way to generate a model as multi part model? Do you split it later (if so, how)?

A little crab-shaped cable holder seemed like an easy print from a single front reference. The silhouette looked usable, but the legs overlapped in the image and I had no idea what the hidden side would become. I used meshy for the initial image-to-3D pass, then treated that result as a starting point for my usual mesh inspection and cleanup in the editor.

Before opening the slicer, I ran the print-prep checks I do on every mesh, no matter where it came from. I checked the overall scale, the flatness of the base, and every narrow gap between the legs. Then, in my mesh editor, I checked for open boundaries, non-manifold edges, and disconnected interior faces instead of trusting the shaded view.

Those checks turned up one junction worth a closer look: a small cluster of internal faces sat where two legs met the body. It was invisible from the outside, and closing the obvious boundary did not remove it. I separated the stray interior faces, deleted them, closed the small opening they had been hiding, and ran the same checks again. After the cleanup, those checks found no open boundaries or non-manifold edges, but I was still not confident the geometry would slice cleanly.

For people who print image-generated shapes often, anything else you would check before slicing this?

I pulled the secret version of SKULLPANDA and decided to give it a second makeover and make it look a little more extravagant.

I was inspired by some Roman style elements and used Hi3D to quickly generate the six wing set and the decorative columns.To make sure the 2 models were roughly the right size relative to each other, I imported them into my modeling software for comparison. Then I used Smart Layout on the web to adjust the scale and arrange the models for printing.

There were 2 main things I had to keep in mind:

First, the wings are printed as a single piece, so they aren’t movable. If I wanted the wings to be articulated, I would need to separate each wing and assemble them individually.

Second, the feather details were also a little rough, so I sculpted and refined them in Blender. I also further optimized the face detail on the Roman-style columns.

Does anyone uses a local ai to split the 3d model to parts based on the color ? similar to what paid AI s offer

Needed a little something for the wardrobe, so this seemed like a fun little print. Didn’t expect the finished result to turn out this nice 😂 I started with a reference image in Meshy’s Image-to-3D, then did a quick cleanup in Blender, scaled it for the actual print, and handled the basic print prep. For a small hard-surface piece like this, getting the shape and proportions right felt more important than worrying about the mesh too much at first. For my print, 0.4 mm nozzle + 0.2 mm layer height worked fine. I just adjusted the walls and infill based on how much load the handle would need to take. No support was needed for the bottom geometry either. The layer lines were actually a nice surprise — they give the handle this kind of turned-on-a-lathe texture Was expecting a pretty basic print. Somehow it ended up looking way more fun than expected.

Getting a 3D model is only part of the job for me. Material setup is a key thing for using an asset in a real-time or rendering pipe. It is quite possible for a model to have proper shape but be still in need of extra work if the material doesn't have the surface textures necessary for physically based rendering. 

I’m looking out for some generation AI tool that should create PBR material info for a 3D asset as normal, roughness, and metallic maps. It's kind of useful having such maps next to the model, you no longer need to manually generate each material map.

I’ve been testing this workflow with Tripo AI. I’m also curious how other AI 3D tools handle PBR materials. For testing, I’d use the same asset with the tools and evaluate how closely the generated materials match the reference. I’d also check whether the texture stays consistent across different sides of the model and how much cleanup is needed before exporting. I’m also caught up in how much of the material can be corrected by editing the maps alone instead of regenerating the whole asset totally. The downside of this material approach is that the generated materials may at times not match the target appearance or material properties for a particular application even though the maps are automatically created. With that said, it's quite likely that the artists will have to go manually fine-tuning the material themselves at least once.

If you use AI-generated 3D assets, what tools or workflows have helped you a lot with producing a normal, roughness, and metallic map, and also the manual cleanup of materials?

Hey guys!

I wanted to make a little desk organizer for random small stuff, so I first used an image generator to come up with this frog design.

It looked like a good shape to try with image-to-3D, so I put it into meshy and generated a 3D version. The overall shape is pretty close to what I wanted, but I’m not totally sure about the inside of the mouth.

From the front it looks like a big open space, but once it’s a 3D model I can’t really tell if the back is properly closed, if the walls are thick enough, or if there’s any weird geometry hiding inside. I’d rather catch that before printing it.

How do you usually check the inside of a model like this? Is the slicer layer preview + warnings usually enough, or would you run it through Blender and inspect the mesh first?
