High-Speed and Powerful Cloud Rendering for CLO 3D

CLO 3D is a 3D fashion design software program creating virtual, true-to-life garment visualization with simulation technologies for the fashion and apparel industries. As a 3D design software offering unlimited design, real-time interactivity, ease-of-use, and accurate materials, CLO has revolutionized design processes for fashion and garment businesses for more than a decade.

In typical 3D modeling software such as Maya or Max, the surface of the 3D mesh is sculpted to create a costume. CLO, on the other hand, creates 2D pattern pieces and sews them to create 3D costumes. This approach is very efficient because the modeling process of the 3D side is minimized, and it is intuitive for those who majored in costume design. The produced costume can be simulated with physical properties such as weave, knit, leather and denim through its physics engine, and fitting information can be checked by placing it on a virtual avatar.

In the traditional, non-digitized costume production pipeline, users need to physically sew a large number of pattern pieces and communicate the results to determine the design. With CLO, you can see the finished garment shape in 3D without having to cut and sew any fabric. Simple corrections, such as modifying the size and fit of a garment, or applying a new fabric, can be performed in a few minutes, so users can create more diverse draft proposals and exchange information more accurately.

As the system requirements of CLO above, iRender provides a dedicated GPU Cloud Rendering Package – GPU Server 3 with one powerful graphic card RTX 3090 and high clock speed CPU 3.90GHz, which will speed up your workflow and rendering process many times.

Why GPU Server 3 is the best solution for CLO users?

1. The hardware configuration not only exceeds the recommended system requirements but also provide high-end options:

  • CLO utilizes Nvidia CUDA acceleration technology for CLO GPU-Simulation and Rendering. So computers with only Intel Graphics or AMD GPU do not benefit from hardware acceleration that speeds up CLO simulation and rendering. In addition, currently, CLO only supports 1 graphic card, does not support multiple GPUs. Therefore, you only need 1 graphic card, and that card has to be powerful enough. GPU server 3 has NVIDIA RTX 3090 – the most powerful graphic card right now.
  • GPU Server 3 has 24 GB vRAM capacity, fitting to the heaviest image and simulations. You don’t have to worry that your entire image or simulation will not fit in memory limit.
  • RAM capacity of 128 GB is many times higher than the minimum requirement.
  • CPU is important in CLO workflow, also, in a non-Nvidia GPU equipped computer, calculations necessary for CLO simulation and rendering are performed on the CPU, and the visual quality of these results is the same. GPU Server 3 has Intel Xeon W-2245 with a high clock speed of 3.90GHz, surely helping you handle the tasks smoothly.
  • iRender provides services with 64-bit Windows 10, which meets perfectly CLO’s requirements.

2. iRender provides high-end configuration at a reasonable price. You can see that iRender’s package always costs much cheaper than packages of other render farms (in performance/price ratio). Moreover, iRender’s clients will enjoy many attractive promotions and discounts. For example, this August, we offer a promotion for new users and discounted prices for many servers, users will take advantage of these to level up their renders.

3. To reduce the rendering time more, users can run multiple machines at the same time. You can use the machines separately or connect them by using Thinkbox Deadline. iRender provides Redshift licenseThinkbox Deadline license for Prime customers. Users, who recharge enough points to become Prime customers, will not only be able to use Redshift/Thinkbox Deadline license without usage or maintenance costs, but also enjoy a lot of exclusive benefits.

4. For CLO users with large-scale projects, iRender offers the daily/weekly/monthly/yearly Fixed Rental packages, which saves you up to 50% of the cost compared to the hourly rental. Please read more about our Fixed rental service here.

5. In addition, users can request extra services to make full use of iRender servers, for example, expand image threshold, increase the size of network drive (Z:), open port, install NVLink, and change hardware. Surprisingly, you get all of these services for free.


With all the outstanding advantages mentioned above, you must have found yourself the perfect choice for CLO simulations. We believe together with CLO, our GPU accelerated Server 3 will bring greater interactivity and speed to artist workflows. What CLO users can get from iRender is not only the best quality products but also the high security and the most comfortable render time.

So, do not hesitate anymore, let’s REGISTER for an account today to get a FREE COUPON to experience our service and reach a new level of cloud rendering.

Thank you & Happy Rendering!
