Dynamic Growing Props for Unity VR

About the project

I’ve built a coastal-dune relaxation scene in Unity—using the asset pack at https://assetstore.unity.com/packages/3d/vegetation/coast-dunes-environment-dynamic-nature-beach-sea-islands-dry-des-309456—and wired it to live HRV input. When a player on an HTC Vive shifts from stress to calm, the world should visibly “blossom.” One tree already does this through Blender Geometry Nodes, but I now need a wider range of props that come alive the same way. Scope of work • Plants and trees that scale, green, flower or otherwise transform as relaxation deepens. • Rocks and minerals that brighten, crack open, or reveal glowing geodes. • Gentle animals or creatures that appear, animate, or grow more vivid with each relaxation tier. Across all assets I’ll need a mix of visual changes (size, color, material tweaks), subtle movement/animation loops, and staged emergence of new details. Technical notes – Unity URP, latest 2022 LTS. – Props must be lightweight enough for stable 90 FPS on Vive. – Animation or growth logic can be shader-driven, Geometry Nodes converted to Unity via Alembic, or scripted with timeline/Animator—whichever keeps draw calls low and authoring efficient. Deliverables 1. Source .blend or equivalent files for each prop. 2. Optimised Unity prefabs with growth states exposed as one float parameter (0-1) so I can drive them directly from HRV code. 3. Short README explaining setup and any required scripts/shaders. Acceptance I’ll drop your prefabs into the current scene, drive the parameter, and expect smooth, artifact-free transitions on headset. When calm HRV is sustained, the world should feel richer and more alive, yet never exceed performance headroom. If this aligns with your skills, let’s discuss the first batch of assets and milestones.
