自适应细分¶

Note
实现尚未完成，标记为 实验功能集 。
当使用 实验特征集 时，将更改 表面细分修改器 ，以在渲染时控制网格的细分。为此，除 视图 和 渲染 设置外，所有其他设置都相同。删除/重命名上述设置，并添加以下设置：
预览
- 层级
- 在 3D 视图中要查看的细分级别，这与原始 细分修改器 上的 视图 设置相同。
Render
- Adaptive
Use OpenSubdiv to give different subdivision levels to near and far objects automatically. This allows nearer objects to get more subdivisions and far objects to get less.
- Dicing Rate
When using Adaptive the Render Levels property gets changed to Dicing Rate, this property is used to multiply the scene dicing rate.
Subdivision Off/On, Dicing Rate: 1.0 - 0.3 - 0.05 (monkeys look identical in viewport, no modifiers).
- 层级
- The levels of subdivision to see in the final render, this works the same as the Render setting on the original Subdivision Modifier.
Known Limitations¶
- Multi-user object data are currently made single users, leading to increased memory usage. For those it is better to use non-adaptive subdivision still.
- Multi-view renders can have some inconsistencies between views.
Warning
Instances are not tessellated individually. Instead, the original object is tessellated and then duplicated on all instances. To take advantage of both adaptive subdivision and instancing you should place the original object at the position of the instance that is closest from the camera.
