Exploring new features in Houdini 18.0 with iRender Cloud Rendering

Houdini 18 introduces SideFX Solaris – a USD-based context for lookdev, layout and lighting that brings procedural tools to this important part of the pipeline. This release also includes SOP-based tools for configuring Destruction and Pyro FX shots, and UX enhancements throughout the software. In Blog’s Today, we will explore new features in Houdini 18.0 with iRender.

New Topo Transfer node transfers

New features now available in the production release of the software include Topo Transfer, a neat new system for deforming a source mesh organically to match the dimensions of a target mesh. In the video above, it looks reminiscent of Wrap, R3DS’s popular standalone topology transfer tool, enabling users to transfer clean, all-quad topology from a stock base model to a 3D character scan. As with Wrap, automating the transfer process should greatly reduce the manual work needed to convert raw scan data into animation-ready geometry. Users can also define corresponding landmark points on source and target meshes to improve the quality of the results the Topo Transfer SOP generates.

Modeling: new Path Deform system - new features in Houdini 18.0

Other new modeling features backported in Houdini 18 Build 499 include the Path Deform SOP. As the name suggests, it deforms geometry along a path, with use cases ranging from creating 3D text to modeling long linear objects like belts or chains. Users can apply secondary deformations like twisting or scaling to the curve-deformed model, and both the mapping of the model to the curve and the curve itself can be animated.

Rendering: new viewport fog system, support for random walk subsurface scattering

New viewport features include a fog system with controls for density, opacity, height and depth range. The fog interacts with scene lighting in real time, and can be rendered to disk using the OpenGL ROP, which now supports 64-bit precision. Other rendering changes include support for random walk subsurface scattering in Karma, the new USD-native render engine introduced in Houdini 18.0.

Leverage The Cloud Rendering Service for Houdini

iRender is a Professional GPU-Acceleration Cloud Rendering Service provider in HPC optimization for rendering tasks, CGI, VFX with over 20.000 customers and being appreciated in many global rankings (e.g. CGDirector, Lumion Official, Radarrender, InspirationTuts CAD, All3DP). Users will remotely connect to our server, install any version of Houdini only one time and easily do any intensive tasks like using their local computers. Based on our previous analysis, AMD Ryzen Threadripper PRO 3955WX is highly recommended for Houdini. This is the world’s only processor family supporting PCIe 4.0, which delivers twice the I/O performance over PCIe 3.0. Moreover, it can accelerate workflows with next-gen GPUs and high-speed storage devices and support 128 PCIe lanes as well. As a final brief, this is a great choice for driving Multi-GPUs.

That’s why I suggest our server 5P (4x RTX 3090) or server 8A (6x RTX 3090) or server 9A (8x RTX 3090) if you are using Houdini to render as well. Take your render performance to the next level with the AMD Ryzen Threadripper PRO 3955WX. Featuring 16 cores and 32 threads with a 3.9 GHz base clock frequency, 4.3 GHz boost frequency, and 64MB of L3 cache, this processor significantly reduces rendering times for 8K videos, high-resolution photos, and 3D models. A faster CPU will allow you to extract mesh data, load textures, and prepare scene data more quickly. Check out our Houdini on multi-GPU at iRender below:

In parallel with providing a variety of additional features for users such as Snapshot, Clone, NVLink, APIs,… iRender team has developed iRender mobile app to help users to render on a mobile phone to control your rendering. With all the outstanding advantages mentioned above, you must have found yourself the perfect choice for Houdini. 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. Last but not least, the cost for the Redshift License is $500. For maximum support to deliver the smoothest rendering experience possible with Redshift on our servers, iRender offers PRIME CUSTOMER a/many free Redshift/Octane floating licenses. Users who top up enough points to become Prime customers will be able to use the Redshift license without usage or maintenance costs. Our opinion is that the customer experience comes first.
