删除的功能（虚拟演练、PRORENDER、声音系统）

为了更好地专注于我们的核心产品，我们有时不得不停止使用功能。对于 R23 Maxon 已从产品包中删除了虚拟演练、声音系统（麦克风和扬声器对象）和 ProRender。

不过对于 ProRender 用户来说仍然有好消息：
展望未来，Maxon 正在将 ProRender 的更新过渡到 AMD，AMD 致力于继续支持 Cinema 4D 用户。2021 年，AMD 将更新 ProRender 集成到下一代 2.0 标准，为 Cinema 4D 工作流程带来好处，包括改进的渲染算法、加速的 CPU + GPU 性能、全光谱渲染、美元支持等。

To focus better on our core product, we occasionally have to discontinue features. For R23 Maxon has removed Virtual Walkthrough, the Sound System (Microphones and Loudspeaker objects) and ProRender from the product package.

There is still good news for ProRender users though:
Going forward, Maxon is transitioning updates for ProRender to AMD, who are committed to continued support for Cinema 4D users. In 2021, AMD will update the ProRender integration to the next-generation 2.0 standard, bringing its benefits to Cinema 4D workflows including an improved rendering algorithm, accelerated CPU + GPU performance, Full Spectrum Rendering, USD support, and more.
