Unity submesh. Feb 28, 2025 · Can I apply a single material over every submesh? I have a shader for outlining an object, how do I apply the material with this shader to all submeshes, not just the last one? This is probably handled by the "Outline Normals Calculator" script. Vertices can be shared between multiple sub-meshes. x 脚本测试代码，有兴趣同学可以把玩一下。 参考 Unity论坛 using UnityEngine; With static and dynamic batching, Unity builds 1 big vertex buffer, with lots of individual index buffers, and calls DrawIndexed many times in a row, but with different index buffer offsets/lengths. hatenablog. Generic; using UnityEngine; [RequireComponent(typeof Unity3D中的SubMesh允许模型由多个子网格组成，每个SubMesh对应一个Material以实现多样化渲染效果。 然而，SubMesh过多会增加Drawcall，影响性能。 在需要不同材质效果或动画优化时，SubMesh是一种灵活选择，但在项目开发中需谨慎使用，并考虑其他Mesh合并策略。 Hello, I’m sorry this is probably a very dumb question but: what is a submesh? The unity docs weren’t very clear on this one… anyway thanks! Mesh里面有这么一个参数 mesh. using System. To control visibility on a submesh, you can either use different materials (or material property blocks) on each submesh and control visibility through materials, or you can disable “Optimize Game Objects” in the “rig” tab in the Unity model import settings to have each submesh be a GameObject you can turn on and off. Basically I created the following class: [RequireComponent (typeof (MeshCo… If I have a object with several submeshes, and all those submeshes are using the same material, how can I pick out a specific submesh and set its material to something else? I guess im mostly confused how you would be able to find the submeshes. Using these methods, Unity performs very little data validation, so you must ensure your data is valid. In particular, you must ensure that the SubMeshDescriptor index ranges and SubMeshDescriptor. However, if I do the reverse and drag a material to the object, it will be placed on a specific submesh. In particular, you must ensure that the SubMesh index range and topology are set to correct values. Collections; using System. A subreddit for News, Help, Resources, and Conversation regarding Unity, The Game Engine. com 毎度外部ツールを使うのも面倒なので、今回Unityエディタ上でSubMesh単位でMeshが出力できる スクリプト を作成しました (ソースは最後)。 プロ生ちゃん以外にもSkinnedMeshRendererないしMeshFilterを持つオブジェクトから、SubMeshを切り分けできます。 After three days of frustration, I finally got a subMesh example working. Dec 22, 2025 · 可以看看Unity Document的解释： Each sub-mesh corresponds to a Material in a Renderer, such as MeshRenderer or SkinnedMeshRenderer. It does this with submeshes too. When you use these methods, Unity performs very little data validation, so you must ensure your data is valid. English version : VRChat用にUDIMでモデルとテクスチャを作ったけど、UnityはUDIM対応してないやんけ！ってなったので、UnityでUDIM想定モデル・テクスチャを楽に使えるようにするツールを作りました。 【Unityエディタ拡張】UDIMツール - えけりあ屋さん - BOOTH 以下2つのツールが入っています 「UDIM Submesh As it is, if I click on the object in the 3D view, it will refer to the object itself and display no information specific to the submesh I clicked on. topology values are set to correct values. You would need to show us the code from that script. Collections. I find it I have a baseball player holding a bat. The exception is GPU instancing which can indeed draw many copies of the same mesh with a single graphics API call. A sub-mesh consists of a list of triangles, which refer to a set of vertices. The hierarchy view looks like this: ->batter_player —>batter ----->body ----->bat (contains SkinnedMeshRenderer component I want) I have a script component in batter_player that contains the I’m learning to use Unity these days, so just a newbie question. If the submeshes used different materials I could simply get array of materials and change the one I want. Question : 同一个mesh，unity怎么知道桌腿用材质1，而桌面用材质2？ Answer : SubMesh 一个Mesh可以有多个SubMesh， 一个SubMesh对应着一个Material， 一个SubMesh可以有多个Triangle。 下面是 unity 5. These functions operate on the underlying mesh data structures involving raw index buffers, vertex buffers and mesh subset data. SubMesh indices, both indexStart and indexCount, must not overlap with any other SubMesh indices. onoty3d. See code examples, tips and warnings from experts and users. May not be the cleanest code, and if you see any improvements, please reply with them. The model has two skinned meshes – one is the body and one is his bat in hand. I’ve successfully built a mesh from a C# script, following this tutorial. So, I know there is some functionality that is particular to submeshes, but I wonder if there is any functionality I’m missing.
