Fix AI 3D Models in Blender: Repair for 3D Printing & Games
Find and fix reversed faces, holes, bad scale, broken UVs, missing textures and AI script errors before you ship a model.
AI tools can now turn a sentence or a photo into a 3D model in seconds. The model usually looks fine in the preview. Then you put it in a game, send it to a 3D printer or give it to a client, and it breaks. This course teaches you how to check an AI-made model in Blender, find what is wrong with it, and fix it. Each lecture teaches one skill on its own demo model, then you open a challenge file with a broken model in it. At the end you put it all together with a 13-step production checklist and take the final test.

Every course is a complete, project-based workflow. Enrolment is on Udemy through my instructor links.
3D Printing from Zero to Hero in Blender
Learn 3D modelling for 3D printing in Blender: FDM, MSLA resin, STL export, slicing, and models you can actually print.
You build real projects end to end (door grip, vase, phone stand, coin, phone case), check them with the 3D-Print Toolbox, and print on filament and resin machines, or send them to a print service.
Architectural Design & Animation in Blender
Model a house in Blender at real-world scale, add Archimesh doors and windows, then animate a walkthrough and a build-sequence reveal.
Interior 3D Modelling & Rendering in Blender
Model and light photorealistic interiors in Blender: PBR materials, stills, animation and 360° views.
Python Scripting for Blender
Learn Python in Blender with real tasks: custom UI panels, bpy, automation, and a CSV data-visualisation project.
Architectural 3D Modeling & Rendering: FreeCAD & Blender
Model in FreeCAD, then clean up and render in Blender and present in Twinmotion.
Model & Rig a Car in Blender for Beginners
Model a car body and wheels, then rig it with drivers and controls for a short drive.
Video Editing in Blender – Beginner to Pro
Edit video in Blender’s Video Sequence Editor: cuts, text, audio, transitions, motion graphics and export.
