What's New in Karma in Houdini 19.5

There are several new features in Houdini 19.5 for Solaris and Karma. These spheres, or particles rendered as spheres, will be present in Houdini 19.5. Houdini’s Karma Render engine is a fantastic resource for rendering realistic images. In this article, we will explore “What’s New in Karma in Houdini 19.5”.

1. Karma CPU

Karma, a physically-based route tracer in Houdini that is tightly connected with USD (it uses USD as its scene description format and acts as a Hydra render delegate). Karma is a brand-new renderer meant to take the place of Mantra for new projects, despite the fact that it and Mantra share some concepts. The majority of VEX shading functions are not supported by Karma (with the exception of certain uses of trace). The lookup functions for VEX geometry and point clouds are not supported. Karma includes two render engines: Karma XPU, which leverages CPU resources as well as the GPU and hardware acceleration, and Karma CPU, which operates purely in software on the CPU. These are Karma’s modifications in Houdini 19.5.

2. Sampling

  • There are now only two choices for convergence mode in the render settings: To avoid confusion with the Variance pixel oracle, the old “Variance” mode was renamed to be automatic. The same path was traced. Automatic now includes the features of the former “Distributed” option. Automatic is now the default. The Advanced tab now includes a setting for convergence mode. (Take note that only Karma CPU use this option. Path tracing is always used by Karma XPU.)
  • Because slow render durations can cause confusion, the Pixel Samples parameter in Karma Render Settings has been renamed to Primary Samples or Path Traced Samples, depending on the convergence mode. 

3. Lighting

Improved light sampling in general. Karma now supports cylinder lights as well as supports the light shaping API (spotlight, focus, and so on). Karma now supports the light filtering API (barndoors, gel), especially it supports diffuse and specular scales, light linking.

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.

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:
