Here you can download the projectiles of the Mojito Scene, which I used as an Example on creating Caustics in Blender with the help of LuxCoreRender. Keep in mind, that the Scene only work in LuxCoreRender. And that it will look a bit different if you aren't using the ACES color space. The textures are from AmbientCG and Polyhaven both under the CC0 license.
