cmiVFX Launches Houdini Shading and Rendering Video
Once you have created UV's 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. Understanding COP networks to modify an image, then use the output as a texture for one of the materials is a focus in this portion of the video.
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. Navigate through shader view and use 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 a our project.
Mantra is a powerful rendering engine, one of the best in the industry, but as any other beasts it need to be mastered. Knowing how to manage samples from the inside out is a 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 Depth of Field works in Mantra to achieve our final result.
