@AqeeAqee I made a version of your extension (I hope its ok to post it here) that uses the grayscale color palette, and has a nice fade-in effect to objects while preserving textures! It was made in inspiration by the game that @richard is making in the livestream, and I figured it could be expanded so as to not take up like 15 tiles but instead render at runtime! (sprites not supported in the effect) The extension is: kiwiphoenix364/pxt-raycasting-mod-grayscale I made a test project (only uses 2 blocks): > **[spooky](https://arcade.makecode.com/19369-97365-38380-10488)** > > Made with ❤️ in Microsoft MakeCode Arcade. There is a new block at the bottom of the list, and the darkness modifier is normally 1, but you can change it with 0 being no darkness at all. The texture visibility determines how bright the textures are, ranging from 0 and higher, with 1 being normal, 0 being white, and colors above 1 getting (quickly) darker as they get higher (you don’t usually want to go above 2). The texture visibility isn’t a recommended setting to change, because leaving it at 1 is optimal most of the time. --- _[View the full topic](https://forum.makecode.com/t/raycasting-3d-render-blocks-edition/12921)._
