Powerful new tool for critiquing your 3D Models

Voxol · Jun 24 2026

I'm a 3D character artist by trade, and getting useful feedback on in-progress work has always been harder than it should be. You post a render and it's either "looks sweet" or silence. This forum is one of the few places I've ever gotten real crits, which is part of why I'm posting here.

So I built a tool to fix it.

The core idea: you pin comments directly onto points on a 3D model, and the pins stay anchored in place as you orbit, instead of someone trying to describe a spot in words ("that edge near the shoulder, no, the other one"). You can also do drawovers for more nuanced notes. It reads GLB/glTF, OBJ, FBX, and STL, and the viewer holds up, so you can turn the model around on web or mobile and it actually looks good.

It's early, but it works, and I'm building it because this is a problem I keep running into and I don't think anyone's solved it well.

I'm posting here because this community actually critiques. I want to hear from people who do it seriously, whether the approach fits how you work, what's missing, what you'd want from it. Tear into it.

The platform is called Voxol if you want to check it out.

I ask chatGPT for this . it tends to be just complimentary first but if asked to do more weighted response it gets more serious . Surprisingly it notices nuances you may miss . Especially if asked right questions like what cultural or time references it can see in the picture, art and details style etc . Surprisingly it can be quite accurate. With time it adapts to your thinking, knows what art aspects you typically question but yet still tend to be re-assuring echo which is not always bad. It helps you to crystalize your own ideas. Find proper words for what you just feel. While listening other people opinions often just makes you completely lost and indecisive .

Would be nice to let such soft to have a dialog in between few LLMs at once . You would still keep proper own-ship of your initial ideas, not something you have to credit to other person too.

@gnoop Would you be inclined to use something like this if there were similar AI feedback features that were a bit more specific and pinned the critique to the location on the art that it's giving the feedback on?

Voxol Indeed , I would love to see such soft in general. the one that could be an easy discussion platform for several LLMs you could subscribe for . it's an idea i got here in another thread but found sort of tiresome to copy /paste what one LLM "think" vs another . And a discussion platform might be fun whatever subject they might be discussing .

FWIW, from the perspective of the person providing feedback, commenting on a model to indicate edits is generally much faster when done over a clean screenshot provided by the 3D artist, as opposed to being given direct access to the model.

In other words, dumping the responsability of capturing screenshots for paintover feedback on to the AD or the concept artist is IMHO a bit unelegant and irrespectful of their time. Personally if someone handed my a link to a 3D viewer I'd still ask for clean screenshots first and foremost, *even* if I end up capturing my own if the ones provided by the modeler are unclear. And then ultimately the modeler would then gradually learn how to present stuff better, which is a win-win.

That said, what you have here does look interesting for the modelers themselves, as a way to take good notice of the various paintover feedback handed to them. I suppose it all comes down to how well this is integrated into a pipeline.

Cool stuff
