So I was working on my game and I found a cool render extension that I wanted to add which would have added a darkness modifier block to the 3d render section, but after I added it my game stopped working and a bunch of different extensions suddenly have a bunch of problems. I don’t know what to do in this situation so some help would be nice ;\_;

The game:

Where did you find that extension? Please don’t use it. It doesn’t follow the conventions of a proper extension and likely will break any project to which it is added.

I found the extension on the raycasting 3d render topic page and it was kiwiphoenix364/pxt-raycasting-mod-grayscale. I’m not sure if it actually was the problem or another extension I added which was supposed to add sight, but I don’t know.

Also thanks, but should I just restart the project since it broke the raycasting extension?
