Substance Painter is the industry standard, and a graduate who has used it is walking into a studio that runs it. Nothing on this page argues otherwise, and if your lab is already deployed and your licensing is sorted, staying put is a perfectly good answer. The reason instructors go looking is rarely the software — it's everything wrapped around it: getting a desktop package approved and imaged onto lab machines, keeping licences straight as a roster changes mid-term, and the students on Chromebooks or ageing laptops who can't run it at home when the lab closes at six.
Mixos removes that layer entirely because it is a web page. There is nothing to package, approve or deploy; a student opens a URL and starts working, and the same account works on a school machine, a library machine and their own laptop. There is a native Mac and Windows app if your lab wants one, but it's optional — the browser version is the full editor, not a cut-down preview.
The part that has no Substance Painter equivalent is the teaching side. Assignments, hand-in, grading and a shared class library are built into the product rather than living in your LMS. You post a brief with a due date and an optional starter model; students hand in from the editor, which freezes a snapshot of exactly what they submitted; your Class tab shows the whole roster including the people who submitted nothing; and you mark the work by opening the actual 3D model, spinning it, and leaving written feedback and a grade on it. Grades come out as a CSV per assignment for Canvas, Blackboard, Moodle or a spreadsheet, because your institution already has a system of record and it isn't this one.
Then there is procurement's question. Generative AI is switched off entirely on classroom accounts — students cannot generate images, textures or models on a class seat, and neither can an instructor. Mixos does sell AI generation on its consumer plans; it is simply not part of the classroom product, and it is not a toggle a teacher can turn on. Increasingly that is the first thing an art department is asked about a new tool, and very little in this category can answer it with a flat yes.
A grant covers a named course and its roster — up to 200 students — for one term, free. It adds 4K watermark-free export, the shared class library and the coursework tools on top of an editor that is already free for anyone to use. Applications are reviewed by hand, usually within a couple of working days, and every one gets an answer either way.
