One Mesh is a powerful tool that combines both skinned and static meshes, along with materials for skinned meshes, ensuring a streamlined and efficient workflow for your Unity projects.V2.2 update is now available, please see release notes for more details.Optimize your Unity projects effortlessly with One Mesh!Streamline complex character models into a single skinned mesh to improve performance without compromising quality.Combine Skinned Mesh Renderers:Supports built-in, URP, HDRP.Flexible combining method: Combine all skinned mesh renderers for a single character, batch combine skinned meshes for multiple characters, or merge multiple characters into one skinned mesh effortlessly!Combine Materials for Skinned Mesh Renderers: Supports Standard shader, URP lit, HDRP lit. Efficiently merge materials to reduce draw calls and enhance rendering performance. Some custom shaders can also be combined. (Current version only supports material combining for skinned mesh renderer not mesh renderer.)Standard Shader (Built-in): Supports Main Textures, Metallic Maps, Normal Maps, and Occlusion Maps.URP Lit: Supports Main Textures, Metallic Maps, Normal Maps, and Occlusion Maps.HDRP Lit: Supports Base Map, Mask Map, and Normal Maps.4. Combine Mesh Renderers:Works seamlessly with static mesh renderers as well.5. Blend Shapes: You can combine materials for skinned mesh renderers that include blend shapes, as well as combine skinned meshes that have blend shapes.6. Asset Saving and Prefab Creation:Automatically save all combined assets for reuse. Create prefabs seamlessly, enhancing workflow efficiency and project organization.Performance Benefits:Significant FPS Increase: Boost your frame rate by up to 200%, ensuring smoother gameplay and a better user experience.Draw Call Reduction: Reduce batches and skinned mesh renderers by 80-90%, combine materials to further reduce draw calls, dramatically lowering the rendering overhead.Optimized for Large Projects: Perfect for scenes with high character counts, ensuring optimal performance even in the most demanding environments.User-Friendly Design:One-Click Operations: Intuitive interface designed for ease of use, making it accessible for developers of all skill levels. No steep learning curve—optimize your project with just a few clicks and save significant time on learning the tool.Known Limitations for the 2.2 Version:Combining skinned mesh can be challenging given there may be many different situations, for more inofrmation, check out our One Mesh tutorial viedos.1. Complex models:Issue: In some cases, when combining skinned meshes with the 'Combine Blendshapes' function enabled, the resulting combined skinned mesh may appear in incorrect positions.Solution: Adjust the transforms of the affected skinned mesh game objects before combining. For instance, modify the rotations (X, Y, Z) of the game object and then combine it to see if the result improves. While generally enabling the 'Combine Blendshapes' function can enhance the overall quality of the combined skinned mesh (even for skinned meshes without blendshapes), it may also cause incorrect positions or animations in some cases.Check out our YouTube tutorial videos for complex model combine process. We will continue updating One Mesh to ensure the best results for complex models.2. Cloth Physics Components, normal maps:Issue: Some components like Cloth physics won't function after combining the skinned mesh. Additionally, normal maps might not appear exactly the same as the original after combining, though the difference is typically subtle.Solution: If your skinned mesh renderer includes a Cloth component, do not combine it with other parts to ensure the Cloth component functions as intended. 3. Custom Shader Support:Issue: Currently, the material combine function only supports Main Textures, Metallic Maps, Normal Maps, and Occlusion Maps. There is no support for other shader settings.Solution: You may still be able to use the combined atlas for custom shaders, but it will be limited to the textures mentioned above. Just remeber to change the shader back to custom shaders after combining because by default after combining, shaders will be set to Standard/URP/HDRP.TIPS:Combining skinned meshes reduces draw calls but be cautious: once combined, all parts are rendered together. Combine only meshes that will be visible simultaneously. Otherwise, even off-camera elements will be rendered, negatively impacting game performance.Key Features:Combine Skinned Mesh Renderers:Supports built-in, URP, and HDRP pipelines.Streamlines complex character models into a single skinned mesh for improved performance.Combine Materials for Skinned Mesh Renderers:Supports Standard shader, URP lit, and HDRP lit.Efficiently merges materials to reduce draw calls and enhance rendering performance.Specific shader support:Standard Shader (Built-in): Main Textures, Metallic Maps, Normal Maps, and Occlusion Maps.URP Lit: Main Textures, Metallic Maps, Normal Maps, and Occlusion Maps.HDRP Lit: Base Map, Mask Map, and Normal Maps.Combine Mesh Renderers:Versatile support for static mesh renderers as well.Asset Saving and Prefab Creation:Automatically saves all combined assets for reuse.Seamlessly creates prefabs, enhancing workflow efficiency and project organization.Performance Optimization:Significant FPS Increase: Boosts frame rate by up to 200%, ensuring smoother gameplay.Draw Call Reduction: Reduces batches and skinned mesh renderers by 80-90%, dramatically lowering rendering overhead.Optimized for Large Projects: Ideal for scenes with high character counts, ensuring optimal performance even in demanding environments.User-Friendly Design:One-Click Operations: Intuitive interface designed for ease of use, accessible to developers of all skill levels.
