Redshift2.6.54版本更新，到底解决了什么问题？

渲染是我们做影视、动画等三维制作都绕不过的一个环节，目前可供我们选择的渲染器也越来越多，今天我们来聊一聊Redshift（简称RS）渲染器。

RS是世界上第一个基于GPU加速有偏差的渲染器，拥有照片级别的渲染技术，首创性地使用了Out Of Core技术，很好地解决了因为场景量过大而导致了显存耗尽的问题。

基于有偏差的算法，使得渲染结算量得到优化，能够保证在物理真实的情况下，更快地进行渲染，可以极大地提高你的工作效率。该渲染器在影视特效、产品表现、栏目包装中都有广泛的应用。

作为RS官方合作农场，VSO很早就与RS展开了全线的合作，蓝海创意云渲染农场先后参与服务了《星辰变》《西行记》《四海鲸骑》《斗魂卫之玄月奇缘》等影视动画作品，其宏大的场景，精彩的打斗场面和出色的角色形象都给人留下了深刻的印象。

今年4月，Redshift更新了2.6.54版本，增加了对3ds Max2021以及Cinema 4D S22的支持，修复了动画网格物体无法正确显示位置、“渲染统计”中无法真正关闭“运动模糊”等问题。

以下为本次更新详情：

* [Max] Fixed potential crash when deleting objects during IPR

* [Max] Fixed a bug where utility buffers for Altus denoising were not saved for the Beauty when using 3ds Max file output

* [Max] Added velocity-based deformation blur support for Bifrost meshes

* [Max] Material override enable-state now ignored during IPR—use Render View’s Clay Mode instead

* [Max] Proxy export now always includes a camera—if None specified, then one is created based on render viewport settings (locked or active)

* [C4D] Added support for Cinema 4D S22. The minimum required version is S22.016

* [C4D] Addressed an issue where custom User-Data would not correctly when used through XRefs with namespaces

* [C4D] Addressed an issue in the tangent data generation

* [C4D] Addressed an issue where the Redshift menu could be appear multiple times in the Cinema 4D main menu, under certain conditions

* [C4D] Addressed a freeze issue on OSX when starting the IPR from the RenderView in versions of Cinema 4D up to R19

* [Houdini] Added support for H18.0.391 and H18.0.416 and dropped support for H18.0.287, H17.5.391 and 17.5.425

* [Katana] Fixed a crash while exporting deep EXR files including the ObjectID AOV

* [Katana] New custom menu for the GrafferThree Redshift light packages

* [Katana] Added support for environment variable REDSHIFT_FORCEQUITONINTERNALERROR, which when set to any value other than 0, will force a hard crash when an unrecoverable error occurs while rendering

* [Katana] Fixed a problem in the GafferThree light packages while adopting for editing.

* [Katana] Point type AOVs channels renamed to X,Y,Z

* [Katana] Fixed a problem with the tangents computation

* [All] Fixed bug in Redshift core that could produce crashes if a 3d plugin issued many error log entries in a multithreaded way

* [All] Fixed bug that could cause hard crash in the core when using a State node to drive material displacement or bump shaders

* [All] Fixed bug that could not update scene if hair min pixel width settings were tweaked

* [All] Fixed bug where the scatter ramp color of a volume grid could affect another volume grid, if the start ramp color was anything else other than black

* [All] Fixed a rare texture sampling crash bug with message “Expression: pNode->GetPhysicalID() != 0xFFFFFFFF”

* [All] Fixed volume grid bug that made color channels not work in some cases

* [All] Fixed bug that could cause a “Mem copy is too big for buffer” assert when using many sprite nodes

* [All] Fixed bug that could produce visual srtifacts when VDBs overlapped
