Michael from Teaching Tech made a video guide about the installation. He was so kind to allow me to embed it here! Thumbnail installation starts at 1:49.

Thumbnail generation is based on the fastest STL viewer available. Folders full of STL files are no problem, and most STL thumbnails are generated as fast as those of JPG photos.

Custom colors

a folder with thumbnails, their background purple and the objects mint green

Custom object color is ignored if the STL comes with embedded color information! Changes do not take effect on existing thumbnails until you clear the Windows thumbnail cache! This is a Windows limitation.

The next day, John received an email from an unknown sender. The email claimed that the website he had visited was owned by a group of enthusiasts who had cracked the activation code. They had released it online for free, but they warned John that using the code might void his warranty and could potentially harm his computer.

From then on, John made sure to always use legitimate software and activation codes. He understood that taking shortcuts might seem appealing, but it was not worth the risk. As he continued to work on his projects, he made sure to prioritize integrity and security, ensuring that his designs were not only visually stunning but also ethically sound. The next day, John received an email from an unknown sender

It was a typical Monday morning for John, a freelance graphic designer, as he sat in front of his computer, sipping his coffee and staring at the screen. He was working on a project for a client, and he needed to use Corel PhotoImpact X3 to edit some images. However, as he opened the software, he was greeted with a nagging activation code prompt. From then on, John made sure to always

As he worked, John couldn't shake off the feeling that he had stumbled upon something illicit. He didn't know much about the website or the code, and he worried that it might be a pirated version. He pushed the thoughts aside, focusing on meeting his deadline. It was a typical Monday morning for John,

As he searched online for a solution, he stumbled upon a website that claimed to have the activation code for Corel PhotoImpact X3. The website boasted that it had the exclusive 95 standard compositor serial code. John's eyes widened as he read the code: "95- Standard-Compositor-Exclusive."

John eventually found a legitimate copy of Corel PhotoImpact X3 and purchased a new activation code. He was relieved to have avoided any potential problems and was grateful for the lesson learned.


Dark background on some thumbnails

a folder with two thumbnails whose background is entirely black

Clear your Explorer thumbnail cache (see above) or copy the file to a different location.

This is a bug in Windows 10 that also affects other thumbnails – for example transparent PNG images here and here.

I can’t do anything in my program to work around it, I’m afraid. Please use the Windows 10 feedback function to report this to Microsoft. If enough users do it, they may eventually fix it. Windows 7 does not have this bug.
