Drop Cast is a Blender add-on for physics-based scattering. It lets you scatter collections of objects across a scene in a few clicks, filling environments with natural variety instead of placing each asset by hand.
The add-on is customisable per asset. You can assign individual spawn probabilities to each object, randomize sizes for natural variation, and adjust the dimensions of the drop area to fit your scene. A quirky "trash" assets pack is included as a free gift; these models are not optimized for games and are best suited for concept art, quick scene filling, or experimenting, since they do not have proper UVs or topology.
Because Drop Cast relies on physics simulation, it may demand higher system performance, and results can vary based on your hardware. Blender version compatibility should be checked on the product's own page before use. A demo video is available for those who want to see the add-on before trying it.
