本软件是由NextLimit机构出品的RealFlow流体动力学模拟C4D插件V2.5.3.0083版，大小：30 MB，支持Cinema 4D R17-R19本软件，支持Win系统，语言：英语。

RealFlow是由西班牙Next Limit公司出品的流体动力学模拟软件。它是一款独立的模拟软件，可以计算真实世界中运动物体的运动，包括液体。RealFlow提供给艺术家们一系列精心设计的工具，如流体模拟（液体和气体）、网格生成器、带有约束的刚体动力学、弹性、控制流体行为的工作平台和波动、浮力（以前在RealWave中具有浮力功能）。你可以将几何体或场景导入RealFlow来设置流体模拟。在模拟和调节完成后，将粒子或网格物体从RealFlow导出到其他主流3D软件中进行照明和渲染。

RealFlow在电影、电视剧、广告、游戏等领域均有非常广泛的应用。电影有：《冰河世纪4》，《复仇者（2012）》，《洛杉矶之战》等等大型国际电影。游戏有：《质量效应3》、《孤岛危机 2》等。

General

– Array Tool: Parameters can’t be animated for meshes.

– Initial State files created in RealFlow | Cinema 4D 1.0 are not compatible with 2.0 version due to the switch from RPC to Alembic.

Emitters

– When using a multi-segment spline with the spline emitter node the “Prev” and “Next” buttons only iterate through the control points on the current segment.

Meshing

– Mesh fluid/emitter weight vertex map computation is limited to a maximum amount of 10.

Parameters

-358 – File paths can’t have unicode characters on Mac OS X.

-519 – Simulation steps configuration from RealFlow | Cinema 4D 1.0 scenes is reset to Auto mode when opened in 2.0 version.

Rendering

– Simulation look on render may differ between multiple simulation/renders unless caching is enabled.

– Objects deformed with Rigid, Elastic and Particle Skinner only support motion blur when using the Point Cache tag.

– Particle render instances are not rendered/recognized by NVIDIA’s Iray.

– Motion blur with meshes doesn’t work with NVIDIA’s Iray.

– Motion blur with meshes doesn’t work with Maxwell Render.

– Particle render instances original objects remain visible during render.

Fixed bugs – Caching

– Cinema 4D crashes on caching if the cache folder field is empty.

– Animated cache offsets do not work in render time.

Daemons

– Setting the same fluid as source and target in a Filter daemon freezes Cinema 4D.

– Attractor daemon “Internal Radius”, “External Radius” and “Planet Radius” parameters should have units.

– Attractor viewport representation does not match its behavior when Attenuated is enabled.

Rendering

– Mesher vertex maps don’t work with Octane render. (Version 3.08 of Octane plugin fixes the issue).

– There is a one frame offset when rendering meshes with motion blur enabled.

Save and Load

– Particle UVs are not loaded in cache mode.

Parameters

– It is possible to type negative values for scene simulation steps and iterations.

Known bugs

Emitters

– Emitter ID value is not preserved on scene reopening.

Splines

– If a segment is removed the configuration of the circles of the other segments is reset.

– Undo/Redo is not working when a control point is added.

Daemons

– Having two or more k Isolated daemons linked to the same fluid makes the isolation value grow as many times as the number of k Isolated linked daemons.
