Rendering Tip - Use Lighting Channels for quick lighting adjustments

2010-10-26T21:57:00.001-07:00

Lighting Channels isolates the effect of light sources on the final rendering, so that:

Balance illumination in scene without adjusting individual lights.
Create dusk and nighttime scene by quickly lowering the intensity of sun and sky.
Get results faster without having to re-render the scene.
Quickly adjust the final rendering to get the lighting effects desired.
Adjust both the sun and sky to create dusk, or nighttime renderings.
Add 'self glow' to objects - such as TV monitors, or illuminates signs, and adjust them the balance with the rest of the scene.

Balanced lighting using lighting channels.

Lighting Channels is an important new feature of IRender nXt which lets you quickly adjust light sources - sun, sky and/or artificial lighting - individually quickly to balance the brightness and light balance of your rendering. (Now: Fully Integrated into the Batch Renderer.)
You can quickly adjust the intensity of each channel with a slide bar and immediately see the effect on the final rendering. This will saves time both in determining the relative intensities to use for light sources and in fine tuning the final image before publication.
While rendering, or after the rendering is completed, you can use the Lighting Channel Wizard to modify the rendered image by changing the intensities of the lighting channels. You can then adjust the intensity of the light sources, or save the Lighting Channel sttings to reuse the same channels in future renderings.

Rendering Tip - Use Self Glow for backlit objects

2009-11-21T09:21:00.001-08:00

(Self glow applied to television screen)

Self Glow illuminates a surface as if it had light shining on it, without actually making it a light.

* Balance illumination in scene without adding additional lights.
* More realistic signs, monitors and projection devices.
* Faster rendering times.

Use Procedural bump maps or materials for water

2009-11-12T21:38:00.001-08:00

if your renderer has special procedural bump effects they can be used to make realistic water which will reflect buildings, sky and other background objects realistically.

Distorted reflections to represent water ripples.
More Realistic highlights from reflection of light.
Realistic transparency caused by ripples and reflection of light.

Tip of the Week - Use 2 Pt Perspective for vertical alignment

2009-10-28T21:55:00.000-07:00

Due to the type of default perspective that SketchUp use, sometimes buildings can become distorted. Using two point perspective can correct these types of distortions.

Two point perspective, sometimes called ‘2D’ in SketchUp, will keep the vertical lines of your model parallel to each other.

If your rendering software supports 2 pt perspective, use it for better renderings when ever you are looking up or down on models with vertical lines.

Use reflective surfaces for better detail

2009-10-26T18:48:00.001-07:00

When making your first renderings you will probably think of adding mirrors and lights, but you may ignore the value of adding reflective properties to other surfaces.

A reflective floor can make the difference between a flat image and a realistic look image. The same is true of metal, wood, plastic and other surfaces... Read more...

Use Section Planes for better interiors

2009-10-23T19:16:00.001-07:00

When rendering the inside of a room it is sometimes a challenge to place the camera properly.
If your renderer supports section planes, you can create realistic renderings of the room itself with a camera position outside of the room.

Use Edge lines for better detail

Edge lines can be very useful for users who are trying to show off detail in a rendered image.

Use HDRi Skies to improve exterior renderings

2009-10-17T14:23:00.001-07:00

Camper rendered with HDRi sky.

HDRi skies are a great way to improve any scene you are rendering. It is a quick and accurate way to give the user a high quality background image and illuminate the scene using the HDRi light intensity and colors.
