Shadow Maps (soft): Creates a "shadow texture" from the point of view of the light source with resolution, blur radius and proximity bias to be selected.
Shadows offers a choice of three types of shadow generation:
Square parallel spot: parallel cuboid light emission.Parallel spot: parallel cylindrical light emission.Square spot: pyramid-shaped light emission.Area: sample-based spatial light emission with an actual geometric shape.Infinite: parallel light emission from an infinitely distant point.Note: The geometrical shape of your light emission will determine the shape of your visible/ volumetric light.
General Tab, dropdown menu Type offers a variety of different types of light sources. When creating a light in Cinema 4D the corresponding Attribute Manager will show a bunch of parameters and tabs (see figure 1) to customize.įigure 1. But before getting too far into the details, let’s explore some of the important basics of light sources in Cinema 4D. With a light source option of creating “foggy“ visible light and some built-in noise functions you can create thin, non-shadow casting clouds or fields of fog in a breeze. The most simple and straightforward approach to creating basic atmospheric effects is using the built-in light sources of Cinema 4D as actual clouds or fields of fog. Thin Clouds and Fog - Visible Volumetric Lights with Built-in Noises Part 1: The Magic of Visible Lights will cover creating clouds, fog and nebulae and Part 2: Erupting Plasma and Sliced Clouds will address solar flares and puffy clouds. Due to their complexity, we will deal with them in two parts. In addition to those mentioned, there are other techniques that are more straightforward, but which you might not think of initially: using only onboard tools rather than the approaches mentioned above. Additionally, Cinema 4D still hosts the aging voxel-based PyroCluster* system, a former standard tool for a variety of volumetric effects. Technical approaches for Cinema 4D* normally are done with fluid- or particle-simulations with contemporary third-party plugins such as Turbulence FD* or X-Particles*. Volumetric effects such as clouds, fog, nebulae or fire-like structures are a common task in the daily work of a 3D artist. Creating Clouds, Fog and Nebulae in 3D Digital Art
