OptiDraw – Advanced Mesh Painting Tool

🎨 OptiDraw || 📖 Documentation || 🗺️ Roadmap || 💬 Forum

Bring the power of AAA texturing workflows directly into the Unity Editor. OptiDraw delivers a frictionless, zero lag painting experience for both static and animated meshes. Engineered with a Substance style workflow, multi submesh support, and pure Burst Compiler performance this is your definitive in editor painting solution.

Optidraw is a professional-grade painting toolset designed to bridge the gap between external texturing software and the Unity Editor. Whether you are creating lush environments with Splat Painting or detailing characters via Vertex Painting, Optidraw provides an intuitive, high-performance experience that doesn't slow down your creative flow.

Built with Unity Burst and GPU acceleration, Optidraw handles complex meshes with ease, supporting advanced workflows like UDIMs and multi-submesh painting inspired by the Adobe Substance workflow.

Core Modules:

• Vertex Painting: High-precision vertex color manipulation for blending, masking, and detailing.
• Splat Painting: Perfect for terrain-like texturing on any mesh, allowing for complex environment blending.
• Texture Channel Packer (Bonus): A powerful built-in utility to merge and optimize your texture maps (R, G, B, A) into single textures for better performance and memory management.
