The Professional & High-speed Cloud Rendering for Realflow

Realflow is a software for fluid and fluid simulation in the 3D industry and special effects. This app is compatible with most 3d platforms. Powered by powerful DY-SPH and DY-PBD solutions as well as utilizing GPU acceleration and processing power, the program has brought a new level of fluid simulation. A number of practical applications of this product in the real world:

  • Games: Crysis2, Mass Effect 3, God of War Ascension, Wolverine, Uncharted 3 Drake\’s Deception, Ryse: Son of Rome
  • Movies and Animation: Pompeii, Shadow Recruit, Resident Evil Retribution, The Impossible, Ice Age 4 and more
  • Television: Qualcomm, Clarins, Fanta Lab, Cabury,…

The strength of Realflow is to create large-scale sock fluid flows, with perfect dynamics simulation. If you are a fan of Pepsi or Coca-Cola and have been amazed by the vivid water effects of their advertisements, then Realflow is the program for you to create:

  • Create immense rivers, streams, oceans
  • Create waterfalls, floods
  • Create heavy rain, light rain, wetness
  • Create white water bubbles, tiny bubbles
  • Create sparkling water in the glass
  • Make water flow according to default shapes
  • Create simulated flow of liquids: chocolate, syrup, honey,..
  • Create flow of fabric

Minimum Configuration

  • Cinema 4D R15 – R24 (64 bit only)
  • Windows 7 (or higher) or macOS 10.9 (or higher) operating systems
  • Intel® or comparable main processor
  • 8 GB RAM
  • 75 MB disk space for installation
  • Network adapter and internet access for license activation
  • RealFlow | Cinema 4D supports GPU-based simulations and multi-core/multi-processor systems.

1. CPU (Processor)

Since fluid simulations are computationally expensive and allocate large amounts of disk space we recommend Intel® i7 or Xeon systems (or comparable) . Vfxarabia also did a test, and realize that clock speed has the biggest impact on CPU performance with Realflow. They recommend those two CPUs:

  • Intel Core i7 10700K 3.8GHz (5.1GHz Turbo) 8 Core –This is one of the highest clock speed CPUs available, and does extremely well with both OctaneRender and modeling / animation applications.
  • Intel Xeon W-2235 3.8GHz (4.6GHz Turbo) 6 Core –Intel’s Xeon W series processors maintain very high clock speeds and have far more PCI-Express lanes than the consumer-oriented Core series.

2. GPU (Video Card)

First, it is a pity to know that Realflow does not currently support multiple GPUs. Second, we have observed that the number of GPU cores makes the difference. As a simple rule, we can say: the more GPU cores, the better. In fact, the Quadro M4000 was about 20% slower than the GTX 970 even though the GTX 970 is almost a third the cost. And even Tesla v100 only has 5120 CUDA cores. Besides, the amount of VRAM determines the size of the simulation and there is currently no fallback on the mainboard’s RAM. With 8 GB of VRAM, for example, it is possible to simulate 12-15 millions of → Liquid PBD particles (assuming that the only open program is Cinema 4D with a scene containing one emitter, one fluid container, and one daemon).

As such, we recommend the NVIDIA Geforce series if Realflow is your primary application. As of October 2020, these are roughly the upper tier of consumer-level GPUs from the slowest to the fastest:

  • GeForce RTX 3080 10GB – Generally speaking, the RTX 3000 is an excellent solid starting point – far faster than anything the 20 Series was, and for a lower price than either the RTX 2080 Ti or Titan RTX. A great choice if you want just one video card for Realflow and it offers the best value for money.
  • GeForce RTX 3090 24GB – Our recommendation for most GPU rendering customers, the RTX 3090 provides the best performance in Octane while also having a tremendous 24GB of memory.

Specially, a simulation with a NVIDIA RTX 3090 (10.496 cores) is about 3x faster than a NVIDIA Quadro K6000 and 9x faster than an Intel Core i7-3930K, for example.

3. Memory

Realflow requires a minimum of 8GB RAM. However, in fact, even for low-poly or simple scenes, you will need at least 16-32GB of RAM for your PC to work with Cinema4d well. If you tend to multitask and this is not your first workstation build, more than 64GB will help you limit data loss and improve Cinema4d stability. That’s also the reason iRender provides our customers 128 – 256GB RAM memory to help hold data of multiple programs running in parallel, so multitasking (running multiple apps at the same time) is smoother and more quickly. We understand the actual needs of the artist, we understand that a modern 3D artist needs to be more creative than just software.

4. Storage

The highest performance drives available today are NVMe based Solid State Drives (SSDs), and these are generally all we recommend for primary drives. SSD will ensure your system will boot as quickly as possible, keeps your system as responsive as possible, and reduces your application/project loading times…

While many other famous render farms (for example Fox Render Farm) also use HDD storage, iRender strongly invests in NVme SSD for the entire render farm despite the expensive cost. We define new era rendering in parallel with fast speed.

Welcome back to iRender. In the previous post, we made a comparison between Redshift and Octane in terms of speed and denoise. Today, we continue with the comparison of 2 render engines on Cinema 4D software. We’re going to render two main scenes, including 1 indoor and 1 outdoor. In the indoor scene, it has simple settings with HDR lights. In the outdoor scene, we’ll compare 2 different lightings. They’re midday lighting and sunset lighting. Let’s get started.
