Free 3ds Max and Corona scripts
These are small MaxScript tools we use on our own architectural and interior visualisation jobs. Each file starts with a header that says what it does, what it targets, the versions we use it on and how to undo it. They were used in our studio setup of 3ds Max 2025/2026 with Corona 12 and 14; we have not tested them on other versions. Save your scene before running any of them.
Each link downloads a small .zip with the .ms file inside.
For how we write and test scripts like these, see How to prompt AI to write 3ds Max scripts that actually work.
Corona auto bitmap loader
Corona auto bitmap loader While its small window is open, it swaps standard Bitmaps you drop into the Slate Material Editor for CoronaBitmap, including every instance in the scene. Untick Enable Auto-Conversion or close the window to stop it. The swaps are not in an undo block, so save first.
More scripts are added here regularly.
How to install
Run the file once by dragging the .ms into a viewport, or with Scripting > Run Script. The loader window opens straight away, attached to the Slate Material Editor window if that is open. It also adds itself to Customize User Interface under the category "Vaars Studio", so you can put it on a toolbar.
These scripts are free to use, provided as is, with no warranty. Test them on a copy of your scene first.
