KarmaXPU Quickstart Pt. 0 – Creating Our Test Geometry

It’s finally time we talk about Karma again. Nope not your spiritual system, but Houdini 19.5’s built in new’ish rendering engine. It’s been making quite fast progress since the time it’s been released a few versions back, so in our opinion with KarmaXPU being in […]

Procedurally Create Detroit Agate with a Karma Shader

If layers over layers of car paint accumulate in the factory over the years they create grey rocks with magic hidden inside. Once you start to cut and polish these rocks all the individual color layers are revealed and create a color explosion. In this […]

A Procedural Polka Dot Shader with Analytic Normals

Today we’ll build a procedural shader that produces a polka dot pattern. While this is quite informative, as we learn how to tile the uv space, the interesting part is creating the normal map. We want to use the implicit sphere equation to derive z […]

Create a Procedural Hatching Shader in Blender Cycles

Today Manu looks at another porcedural area of Blender, the shader editor. We build a procedural hatching shader that will come in handy for your next NPR project. You’ll learn about generating procedural lines and doing 3D shading yourself inside of the shader using the […]

Holiday Giveaway: Mantra Thinfilm Shader

Happy Holidays! Turns out rendering spherical objects has become our very own tradition by now, so as an addon to Monday’s tut and the question “But can u do it in Mantra?” – Here’s a small present hastily thrown together by yours truly: A VEX […]

Rendering Houdini Effects in Eevee

Since the release of Blender 2.8 people are looking into Eevee, their rasterisation real time render engine. Eevee is free and gives good and quick results, so why not bringing over effects from Houdini to render there. In this tutorial I’ll walk you through the […]

Giveaway: Redshift Thinfilm Shader

Head over to our Patreon for the free .hip files. We recently had to create a physically based thinfilm shader in Redshift. This is the result. It’s a slightly simplified version of this OSL shader from gamedev.net, implemented using purely Redshift nodes.

Easy Soap Film Shader

By far the most frequent question we received after our minimal surfaces tutorial was “how do you build that bubble shader?”. The wait is over – in this tutorial we’ll go over how to build a plausible soap film shader in Houdini’s Mantra and Octane […]

Colored Trails (Point Advection & Rendering)

One of the great things about the Houdini community is that we’re always confronted with clever questions and with clever answers too. “How do I color strands using an image’s color palette?” was the comment on Vimeo that led to this setup. Yet when talking […]
