Light an Interior with One HDRI and a Window: the 10-Minute Setup
To light an interior with one HDRI in Blender, switch to Cycles, load the HDRI as an Environment Texture in the World, rotate it so the sun comes through the window, and put an area light with Portal ticked in the window opening. Untick Shadow on the glass, then brighten the room with Exposure ratherContinue reading “Light an Interior with One HDRI and a Window: the 10-Minute Setup”
How to 3D print something you made in Blender
The route from a finished Blender model to a printed part: millimetre units, apply scale, a 3D Print Toolbox check, the right STL export settings, and a size check in the slicer.
Does your 3D model need unit scale 0.001? STL files have no units
STL has no units, so size problems start in Blender. Here’s when unit scale 0.001 helps, which STL export options to use, and how to check the size.
AI-written Blender script gives an error: how to read it and fix it
An AI-written Blender script that crashes usually fails for one of four reasons. Here’s where to find the error, how to read it, and how to fix each one.
Why does my AI-generated model look inside out in Blender?
An AI-generated model that looks inside out has faces pointing the wrong way. Here’s how I find them with Face Orientation and fix them in Blender.
How to fix a non-manifold AI 3D model for 3D printing in Blender
AI-made models look fine in the preview and then fail in the slicer. Here’s how I find and fix non-manifold geometry in Blender before export.
Make a Car Wheel Spin from One Control with a Driver
To make a car’s wheels spin from one control in Blender, parent the whole car to an empty, then give each wheel a driver on its X rotation that reads the empty’s Y location in World Space, with the expression -var / radius using the wheel radius in metres. You then keyframe only the control,Continue reading “Make a Car Wheel Spin from One Control with a Driver”
Rename 100 Objects at Once with Five Lines of Blender Python
Duplicate a chair 100 times in Blender and the Outliner fills up with names like Chair610x666x1134.001, .002, .003 and on up to .099. That’s fine until you need to find one chair, export the scene to a game engine, or send the file to someone else. Renaming them by hand takes ages. I use fiveContinue reading “Rename 100 Objects at Once with Five Lines of Blender Python”
Save furniture to a Blender asset library and drop it into any room
Mark as Asset alone doesn’t give you a library. Here’s how to save a chair once in Blender and drag it into any room file, with the setting that stops the Asset Browser looking empty.
