Maxwell Render 2.5 User Manual

Chapeter 2. The Maxwell Render Reality. Understanding Maxwell’s Approach to rendering | 8

2.02 Environment

Maxwell Render provides a complete Physical Sky system with a sophisticated atmosphere

model that reproduces skylight conditions at different hours, dates, and locations. The

Physical Sky system is a simple way to obtain extremely accurate lighting in your scenes.

The atmosphere parameters allow users to customize the look of the sky and the resulting

light in the scene, ranging from common Earth values to exaggerated fantasy skies. Users

can also create presets of the sky settings to quickly load a new sky or share their presets

with other users. It’s also possible to save the current sky as an HDR map.

2.03 Interactive workﬂow

With Maxwell Render you will get an awesome interactive workow, saving a lot of your

time as you don’t need to re-launch the render for every parameter you adjust.

First: Maxwell Render allows you to re-expose your image interactively during the render

process. Multilight enables you to adjust the intensity of all the individual or grouped lights

in your scene during or after the rendering process to get the results you are looking for.

It is also possible to resume a render after it has nished rendering.

The exposure is the level of brightness of the nal image. With most conventional rendering

engines, if your image is too dark, you have to re-render again. In Maxwell Render, you

can adjust the exposure (adjust the level of brightness) during the render, or even after

the render has nished. Moreover, if you enable Multilight, you can adjust the intensity of

the different lights in your scene separately even after the render has nished.

Second: Maxwell Render includes a truly interactive render preview, Maxwell Fire (which

stands for Fast Interactive Rendering), which allows you to preview your scene in a fully

interactive window (in Studio and in those plug-ins where Maxwell Fire is available),

displaying a great quality preview render of your scene in seconds. This makes it much

faster and easier to adjust your materials, adjust the environment conditions, set up the

camera parameters or your emitter’s intensity and color, and see the results in real time.

Again, Maxwell Render is a huge time saver in your pipeline.

2.04 Cameras

Cameras in Maxwell Render™ operate completely different from those in other render

engines. Traditionally, most render engines use a pinhole camera. This type of camera

simulates a tiny hole that allows light rays coming from the scene to reach the viewing

surface. Instead, Maxwell Render™ simulates a real camera with the associated lens set,

diaphragm aperture, diaphragm blades and various other settings. By using this type of

camera model Maxwell Render™ can automatically simulate depth of eld or aperture

diffraction.

Along similar lines, motion blur in Maxwell Render™ is not produced as a post-process.

Maxwell Render™ considers the moving objects to have random positions along their

trajectories during the camera shutter speed time. This creates a natural and realistic

motion blur.

Maxwell Render’s SimuLens™ system allows you to simulate the shape of the diaphragm,

creating realistic lens diffraction effects. It is also possible to simulate the scattering of

light inside a lens system, an effect typically called “bloom”.

2.05 Materials

Maxwell Render™ materials – called MXM – are dened in a physically correct manner by

their BSDF functions (Bidirectional Scattering Distribution Function), making it possible

to build up different layers of materials in the same object, like other BSDF or SSS (Sub

Surface Scattering) effects. Thin coatings are also available for very subtle and realistic

effects such as thin lm interference effects for the multicolored look of a thin layer of oil

in water, or soap bubbles.

Maxwell Render™ materials are not only physically correct but also very exible and

versatile.

Bump/ Normal Mapping, Displacement, Dispersion of light and Emitting properties are

other characteristics available in the Maxwell material system.

With Maxwell Render 2 and its new stacked layers system, it is possible to create

sophisticated materials easily. Materials can now be stacked in a layered way, so you can
