Stylized Rock Generator v1.0.1
Create stylized rocks in just a few seconds. Tweak parameters and see the result in real-time. You can also use our custom-made rock materials to accomplish your desired look and feel.
◼ Compatibility ◼
– Works in Unity 2019.4 and above
– Support Universal Render Pipeline (URP) and High Definition Render Pipeline (HDRP)
– We do not support Built-in Render Pipeline yet
Materials
The package includes seven base shaders and 19 pre-made rock variation materials (mossy rock, sandy rock, snowy rock, Crystal, etc.). You can change shaders in Shader Graph.
Rock shaders use tri-planar projection instead of UV maps. So you can assign one material to all rocks in the scene, which helps reduce draw calls.
Future updates
Add different primary rock shapes and several rock gen algorithms to cover various rock types, including cliff rocks, seashore rocks, crystals, desert rocks, etc.
Add a new tool to paint rocks on the field and control them intuitively.
Manual: Link
Note: All the screenshots are captured in Unity 2021 HDRP. So it may look slightly different in other Unity versions in terms of lighting.
