Blender 3D New Hair System to Lightwave 3D FiberFX Workflow
Slick3D Blog

2w ago
In this tutorial I'll show you how to convert Blender's 3D new hair system to Lightwave 3D FiberFx. For this, I am using the Einar's demo file that can be downloaded here. Also, you can become more familiar with Blender's new hair system features by watching the developer's video here. Blender's 3D new hair system cannot be exported directly as curves like 3D artists are use to do with the classic hair particle system. To be able to export the new hair system curves to another software, the artist must select each created hair bundle (which is a geometry nodes assembly) and switch to sculpt mo ..read more

In the new Linux versions, the DotNet SDK has conflicts with NSS or ca-certificates. Different types of failures are raised in relation to a specific operation. A more detailed explanation of the problem can be found here. Compiling Unreal Engine on Linux had always been very straightforward. Unfortunately, on Fedora 36 we got the DotNet SDK conflict error. Unable to load the service index for source https://api.nuget.org/v3/index.json The error message above and others are raised in the moment of the project files generation, the last step before to run the command make to build Unreal.

For whom in trouble to configure opencl in Houdini, it’s needed to write the GPU card configuration in the correct order inside houdini.env file. The Houdini artist should use the windows shell inside Houdini to query information about the available opencl devices: Menu Windows > Shell. The windows shell opened: Then, the Houdini artist should type hgpuinfo -l to list all available opencl devices in the system: The returned device list: In this example, the artist desires to use the opencl CUDA, of course.

How to render volumes faster in Lightwave 3D?

Lightwave 2018 brought a new PBR render engine with an unprecedented volume system in Lightwave's history. All new features are very nice. However, Lightwave still chokes when have to do intense computations. Of course, this is a big problem because, usually, production demands heavy scenes and intense computations from the render engine. But, there's hope for Lightwave native render engine. With some tricks, it's possible to obtain decent render times when rendering more complex scenes. One thing to do is baking the textures when using complex shading networks. Another thing is never use brut ..read more

Fedora 34 is a great Linux system release. It brings Gnome 4 and is the most stable Linux distro I've ever used. Then, with an excellent perfomance, it is the perfect environment to work with Houdini. This tutorial will show how to overcome little problems that occur when launching Houdini for the first time in this system. The installation process is very straightforward: the Houdini artist only needs to execute the houdini.install script and follow the instructions. OBS: I used the production build 18.563. I had problems installing the python 3 distribution. But this specific subject is for ..read more

How to apply user created attributes in a V-ray shading network inside Houdini
Slick3D Blog
by Luiz Carlos Lobato
1y ago
In this tutorial I will show you how to use an attribute created in SOPS inside a V-ray shading network. In this practical example, I have a 3D model of a woman and I will create a mask to control the blending factor between a metal material and a dirt material. The dirt material will be applied to the white part of the mask. The black part will hold the metal material. I used the measure SOP to create the curvature attribute. Inside the material network matnet1, I created a V-ray Material Builder to adjust the mask. V-ray for Houdini offers four user data nodes to retrieve information from u ..read more

The last update of Tyflow added nodes to work with openvdb volumes. Then, for the first time, 3DS Max artists can create meshes and effects using the openvdb library. In this tutorial I will show you how to do a “dented” or “bulge” effect using Tyflow. The efffect is not complicated. The artist only have to take care to follow the steps in order to achieve the bulge effect. Let’s get started. I’ve created a scene with a Torus, a Sphere and a Teapot object. The Torus is the object that will be cut. Then, I’ve already placed the Sphere and the Teapot (the cutters) at the desired place. After t ..read more
