Generate outlines using our Edge Detect VOP! We have also included the Front Face VOP for Karma as part of our Standard Library!

The Edge Detect Shader works in Karma Materials as well as MaterialX and renders in Karma CPU & XPU. Additionally, you can use the Mtlx Front Face VOP from our library to get normals only facing the camera, this helps in shading materials which are transparent and have opacity mixed. there is a VEX version of the HDA available as well for Mantra & Karma.

Elevate your look development with our powerful Fresnel VOPs for Karma! Discover the magic of Thin Film Fresnel, Fresnel, and XRay VOPs to create stunning materials.

The Fresnel, Thin Film Fresnel & XRay Shader work in Karma Materials as well as MaterialX and render in Karma CPU & XPU. Additionally, there is an Index of Refraction Library preset that gets updated from time to time and can be used within shaders. There are outputs for kr (reflection_light), kt (transmission_light), R (Reflection Vector) & T (Transmission Vector).

The kr (reflection_light), kt (transmission_light), R (Reflection Vector) & T (Transmission Vector) are also available as individual VOPs as part of our Standard Library.

We are excited to bring you the Mask Falloff VOP Shader & SOPs for VEX Shaders in Houdini! Generate quick masks within shaders instantly 🎨

The Mask Falloff VOP Shader & SOPs work in Mantra & Karma CPU and are VEX Based. It can be used to generate quick masks for shading maps and works similar to the Attribute Transfer SOP but in shaders and is SDF-based!

Our VEX Shaders, Karma Material & MaterialX HDAs streamline your workflow by providing presets for AOVs, Mattes, and Utility nodes for Mantra, Karma CPU & XPU. The IPOPs Standard Library includes over 70+ HDAs to enhance your projects.

🏃Get the Motion Vector VOP Shader & SOPs for VEX Shaders in Houdini! Generate quick motion vectors on the go for geometry, particles & volumes!

The Motion Vector VOP Shader works in Mantra & Karma CPU and is VEX Based. The Motion Vector VOP can be used to generate quick motion vectors for compositing and has two methods (forward frame method for mantra only and velocity-based method).

Works in Mantra & Karma CPU.

The Particles AOV Bundle works in Mantra & Karma and has options for Mantra VEX Shaders, Karma VEX Shaders (CPU only), Karma Material (Karma CPU & XPU), MaterialX (Karma CPU & XPU).

In this example we can see how the Particles AOVs Bundle is used specifically in Karma Materials, there are similar nodes available in VEX Shaders & MaterialX. The node is available in shaders and settings can adjusted directly within the material giving users easy access to adjusting AOVs for renders. The IPOPs Particles AOVs Bundle Maker is a SOP level tool that gives artists quick access to previewing AOVs in the viewport itself and overrides the material settings using attributes. This allows reusing shaders on multiple objects and generating dynamic AOVs based on the current particles.

The Geometry AOV Bundle works in Mantra & Karma and has options for Mantra VEX Shaders, Karma VEX Shaders (CPU only), Karma Material (Karma CPU & XPU), MaterialX (Karma CPU & XPU).

In this example we can see the Geometry AOVs bundle specifically for Karma Materials, there are similar nodes for VEX Shaders & MaterialX respectively. The node is available in shaders and settings can adjusted directly within the material giving users easy access to adjusting AOVs for renders. The IPOPs Geometry AOVs Bundle Maker is a SOP-level tool that gives artists quick access to previewing AOVs in the viewport itself and overrides the material settings using attributes. This allows reusing shaders on multiple objects and generating dynamic AOVs based on the current geometry.

The Volume AOV Bundle works in Mantra & Karma and has options for Mantra VEX Shaders, Karma VEX Shaders (CPU only), Karma Pyro Material (Karma CPU & XPU).

In this example, we can see the Volume AOVs bundle specifically for Karma Materials. The node is available in shaders and settings can adjusted directly within the material giving users easy access to adjusting AOVs for renders in IPR. The IPOPs Volume AOVs Bundle Maker is a SOP-level tool that gives artists quick access to previewing AOVs in the viewport itself and overrides the material settings using attributes. This allows reusing shaders on multiple objects and generating dynamic AOVs based on the current volume.

Hi,

I have recently created a set of 70+ HDAs called the IPOPs that aim at creating AOVs, Mattes & features for rendering. IPOPs are operator workflows designed to streamline shaders and AOV development in Houdini. With our toolset, artists can easily standardise their networks and access specially developed nodes for various renderers and presets, increasing efficiency and creativity.

Get the IPOPs here! [chakshuvfx.gumroad.com]

Renders in Karma & Mantra.

1. The Standard Library: Set of HDAs that help artists create quick shaders and AOVs and contain useful Utility Nodes such as Fresnel for Karma (CPU & XPU), Mask Falloffs in Shaders etc. The HDA library is constantly updated with new nodes to assist artists in speeding up their workflow and creating a streamlined system thereby increasing efficiency and creativity.

2. The Geometry AOVs: A set of remade common geometry AOVs for artists to quickly generate AOVs, Mattes & Utility Passes for Compositing.

3. The Particles AOVs: A set of remade useful particle AOVs for artists to quickly generate AOVs, Mattes & Utility Passes for Compositing.

4. The Volumes AOVs: A set of remade volume AOVs for artists to enhance their FX using AOVs, Mattes & Utility Passes for Compositing.

We have a wide range of Bundles available for various workflows & we support both Houdini Apprentice & Houdini Indie! For any enquiries please email support@chakshuvfx.com

I will be posting constant updates and developments here.

Hi everyone,

I am getting an error whenever I try to blackbox HDAs.

--------------------------

Traceback (most recent call last):
File "<stdin>", line 17, in <module>
File "C:\PROGRA~1/SIDEEF~1/Houdini 20.0.625/houdini/python3.10libs\digitalassetsupport.py", line 39, in create_instance return _create_vop_instance(node_type)
File "C:\PROGRA~1/SIDEEF~1/Houdini 20.0.625/houdini/python3.10libs\digitalassetsupport.py", line 105, in _create_vop_instance
assert not "Could not determine the VOP context for this VOP asset"
AssertionError

--------------------------

This happens for some HDAs and some blackbox correctly. I am not sure if it is because these HDAs are Material X nodes & Material VOPs (guess I saw the same thing happen randomly with Vex VOPs in shaders as well) or is it because I had previously saved the HDAs as a different name and did a "Save As" to rename the HDAs and format the names correctly or is it some other issue?

Any information or help would be really helpful!

Thanks!

Created a procedural rig using the scatter and align so the groom can adjust quickly on the fly. A bit rough but had fun building this setup for an Eye.

Created a simple spiral rig using a for-each and a null with a folder parm. Had fun matching the pillow spirals and animating them!

Hi newmethos,

In the Karma Pyro Material just unplug the 'Karma AOV' nodes if you do not want the aov_fire and aov_scatter. These nodes were designed to automatically create Render Vars within the shader so you do not have to recreate them again within the Karma Render Settings again.

It is a bit different from the usual Mantra Process where you have to bind export attributes within the shader and then add them in the Image Planes again to create custom AOVs.

If you can email your findings to SideFx support with Side Effects Support Ticket: #148351 (BUG #134678) it might help them understand the bugs better.

I have raised a bug report for the same.
