cmiVFX Launches Houdini Shading And Rendering Video
Watch High Definition Training Videos For The Visual Effects Industry Instantly From Anywhere In The World.

Princeton, NJ., July 16th, 2009 — cmiVFX | cmiStudios launches a brand new video for the Side FX Houdini Software application. The most frequent request from our customers was involving rendering and shading issues with the Houdini package itself.. We assembled a list of the most frequently asked questions and compiled a video knowledge base in this 4 hour Hi-Definition feature. Online documentation for this subject is nearly non-existant. We have successfully filled the void with an intense, fast paced video. There is so much information in this video, that artists will certainly have every tool necessary to complete any render task. Additional topics such as lighting and materials are covered in great depth. When it comes to high end CG and VFX training, there is only once choice… cmiVFX. This video is available today at the cmiVFX store. cmiVFX Video Player Online Store http://cmivfx.com/store/Browse.aspx?Category=11 [cmivfx.com]

Introduction to Materials:
A very important step prior to the rendering process is defining the aspects of the surface of your objects. This action is achieved in a wide variety of ways in Houdini and is crucial to start somewhere neutral. Learn how you can create materials and how you can assign them to your objects as well as components.

Materials in Depth:
To have a deep understanding of what makes a material believable, it is important to understand the materials pipeline. Houdini extends its procedural workflow into all aspects of the application including shading networks. It is important to know the many ways of application to surfaces. In addition to that, Houdini lets you compile the shaders inside of it in a unique way. It lets you not only write shaders with code but with visual blocks called VOPs as well. Knowing that, the artist will have many options, so we will go through these options on how to create better, proper materials for your objects.

Rendering Tools:
Houdini has a lot of rendering tools that can benefit its users when working. We explore different tools like the render region tool, render view, MPlay, render nodes or output drivers, comparison tools and more. This will allow the artist’s workflow to be optimized for speed. Waste less time performing long test renders and spend more time tuning the look of your render.

Project Start:
We create real projects at cmiVFX and we are happy to delve deep into a project that utilizes a big part of the rendering technologies available in Houdini. In this section, the project is introduced. The final result of this project is discussed as well as its modeling and UV sets used in the scene.

Direct and Indirect Lighting:
The rendering process as a whole, is about calculating the interaction of the lighting in the scene and outputting the result. Knowing about light and its physical properties is a very important step to understanding how to work out lighting inside any software. Understanding direct and indirect light is discussed in length with graphs and tests.

Translucent Materials:
In order to get to the next level of lighting calculations comprehension, We will show the methods of normal propagation for surface shading using the information gathered earlier. This resulting data helps create a translucent material inside Houdini.

Global Illumination:
With the information gathered so far about the importance of the indirect illumination we will go through different ways to create indirect illumination inside Houdini, like the VEX global illumination light shader, PBR, photon mapping … etc, and we will also talk about one of the methods with which you can have indirect illumination on a per object basis. Let us investigate Image Based Lighting and how you can convert an image to the .rat format preferred by Mantra, then talk about light linking in Houdini.

Simple Materials Application:
This section is geared towards creating and applying materials inside the main project; finishing the lamps surface shaders, then working on the materials that do not need texturing for other objects in the scene.

Textures:
Once you have created UVs for geometry you can assign procedural or image based textures to surfaces. This task and others, like creating the corresponding materials for our objects and texturing them will be covered in a step by step method. Creating and working with a COP network to modify an image then use the output as a texture for one of the materials is also discussed in this portion of the video.

Displacement:
Displacement mapping is a very important way to add details to your objects without high resolution modeling. Having a good grip on how to create some displacement shaders for materials is essential. Use the shader view and learn about important parameters like the displacement bound and true displacements.

Sampling in Mantra:
Fine tuning and looking good. That is what this chapter is all about. What makes a shader and light good and final? Working on finishing touches, like adding some objects to reflect in our render, adding some lights, making some reflections and light linking and many other subjects compose the final touches of our project. Mantra is a powerful rendering engine, one of the best in the industry, but as any other beasts it needs to be mastered. Knowing how to manage samples from the inside out is phenomenal for fine tuning your scenes. We are going to look deep into how Mantra manages samples; also as an additional bonus we will have an overview on how to apply Depth of Field to achieve our final result.

It's good, I watched it in the morning…get it! ;-)

cmiVFX Guys!!
Your are the Best!!!

Its what i am waiting for, but i have to wait till 7/21 to be able to purchase it. I have almost all training from cmivfx, they are awsome !
A couple question, do it cover the basic of Vop network and coding ? And do u think that u can make your own materials after watching it ?
Cant wait till i get it

hey new user but is still waiting for pass and log in
how long does it usually take before those are sent
best regard

I can say that this is awsome……

There is no much coding of VOPS. Just simply a translucency shader will be coded.
