Blender镜头模拟插件 Lens Sim

Lens Sim是一款基于真实光学数据模拟相机镜头的Blender插件，其最新版本需在Blender 4.5及以上版本中运行，并仅支持Cycles渲染器下使用NVIDIA OptiX GPU或CPU进行渲染。该插件通过扩展标准相机功能，可模拟包括色差、暗角、畸变、镜头柔焦、呼吸效应和自然散景在内的多种物理镜头特性，有效弥补标准相机渲染过于“完美”的缺陷，赋予作品更具电影感的有机质感。它提供完整的Blender工作流集成、基于专利数据的真实光学精度、自定义镜头设计能力及渲染农场兼容性，同时内置从广角到长焦的数十款真实镜头模型及丰富的镜头参数调节工具。需要注意的是，由于采用OSL相机着色器技术，其渲染速度会低于原生相机，且目前仅限Windows系统与NVIDIA OptiX显卡获得完整GPU加速支持。

版本：LensSim-3.0.0与 LensSim-2.3.1-LTS

Lens Sim。The newest version of Lens Sim only works when rendering with NVIDIA OptiX GPU’s or CPU in Cycles. It uses the OSL camera shaders that were introduced in Blender 4.5, so make sure you are using the newest Blender version. Render with Real-World Lenses
Lens Sim is a Blender addon created to simulate camera lenses based on real-world optical data. By extending the standard blender camera you can easily choose and render dozens of lenses in Cycles. By simulating the physical characteristics of glass and the aperture opening we get common lens effects such as chromatic aberration, vignetting, distortion, lens softness, focus breathing and natural bokeh shapes. These effects contribute to the organic, imperfect look of physical photography. The standard camera provides an idealized, perfect clean render that misses out on these unique characteristics, making images feel sterile or too “perfect,” which can detract from a “film-like” look. This addon inspires to improve that. Key Features
Full Blender Integration Lens Sim is seamlessly integrated with Blender’s native camera and Cycles rendering engine. With multi-camera support, you can maintain your standard workflow when designing shots. Whether you are starting from scratch or adapting current scenes, the process of creating and converting cameras is simple and intuitive. Real-World Accuracy Built on actual lens patent data, Lens Sim replicates the optical characteristics of real-world lenses, from intricate distortions to natural bokeh. Experience professional-grade optical effects like chromatic aberration, lens distortion, focus breathing, and precise depth of field. You get true-to-life results without needing complicated geometry setups.
Custom Lens Design You can easily create your own unique lenses, adjust their specifications to suit your needs, save your designs for future use, and share them with friends and fellow enthusiasts. Unleash your creativity and take your optical projects to the next level! Render Farm Compatibility Lens Sim works native within Blender, without relying on the addon itself during rendering. This means once your scene is set up, Lens Sim’s features are fully integrated into Blender’s system, allowing it to run seamlessly on any render farm that supports Blender. Note that the render farm must support OSL camera shaders that was introduced in Blender 4.5.
Editing Tools Tailor lenses to specific scenes by adjusting parameters like custom chromatic aberration ramp, tilt shift, add extra lens distortion, use a custom aperture image, emulate anamorphic effects, add swirliness to your bokeh, extend the field of view beyond the original lens design and add lens dirt.

Consider Before Purchasing
Although this product is optimized to the best of my capabilities, it will always be slower than the native Blender camera. AOV passes will also be negatively affected by the optical vignetting. Also, some features in Cycles, in particular the Vector pass and Window texture coordinates, require inverse mappings from rays to image coordinates. This is not yet supported with OSL camera shaders. Be sure to read the Documentation (link) section and Tutorials before buying and for a full breakdown of the system and its caveats.
The addon was developed and tested on Windows. OSL camera shaders only work with GPUs that support OptiX, which means that you can render with a GPU only on compatible NVIDIA graphics cards. CPU rendering is also supported, but much slower.
I do provide support for the older version of Lens Sim, v2.#.#, Blender 4.2+. That version works on all GPU vendors, but it will render ~50% slower and has a more complicated setup, where I simulate the lenses in a material setup. Except for fixing bugs and providing support, I will not add new features, as I want to focus on the current version that uses OSL camera shaders.
I have opted in for all future Blender Market sales, so keep an eye out for those :)
