The Transform Effector Shader by an independent creator lets developers transform thousands of actors, foliage, and PCG instances directly in the material using World Position Offset. Powered by a single Blueprint and flexible material functions, this GPU-driven system runs entirely without heavy setups.
Artists can build large-scale visual effects and dynamic transformations that are both lightweight and easy to integrate into existing materials. Because the shader changes only the visual appearance of objects, collision and actor transforms remain completely unchanged.

• Transforms thousands of objects simultaneously using World Position Offset on the GPU
• Includes a single Blueprint paired with flexible material functions
• Maintains unaffected collision and actor transforms while altering visual appearance
• Supports procedural environments, foliage effects, world deformation, and interactive visuals
