Try Auto Reflections
Auto Reflections can streamline model making and help you start processing renderings faster. The nice thing about Auto Reflections is that when you turn this option on, it just works! Read More: Rendering Tip - Auto Reflection
Reuse Setup Options (Render Settings)
In this rendering tip we'll show you how to make a new rendering with the same render settings used in a previously completed rendering. It's easy to reuse render settings and even share render settings with other models.

IRender nXt Views
In this rendering tip we'll show you several ways to make renderings with the same camera settings used in a previously completed rendering. We'll share camera settings from one model to render another, and recall camera settings to create renderings for a design meeting with the client.
Two models rendered from the same vantage point:

Renderer Not Responding? A few Tests
We sometimes get reports that the rendering program has crashed, or that the rendering has stopped, both of which are somewhat unlikely. When we receive models that are suspected of this behavior, we have a test that I would like to share.

Batch Rendering Option
This guide will help you use Batch Rendering to improve your project workflow. Learn how to use Batch Rendering to process multiple renderings sequentially, and while you're away from the office!

Test Your Lighting Design
An easy way to test your design for lighting is to set Color Rendering Mode to Clay

Biased or Unbiased? Why Choose When You Can Have Both!
Biased renderings by IRender nXt are high quality and fast.
Unbiased rendering methods emphasize accuracy over efficiency. The lighting solution calculated is as accurate as possible.

Use SketchUp Layers to Reduce Rendering Times
You can reduce rendering times for your SketchUp models when you use layers to group light fixtures. Turn off the layers for any lights that don't illuminate the scene and you'll be rewarded with renderings that are completed significantly faster.
Use reflective surfaces for a more realistic image
One of the best things that you can do to improve a rendering is to focus on the details. It’s the details that can increase realism of a rendering and one detail that many users over look is adding reflection to all the materials in a model that need it. Not only that, but you must also apply the correct kind and the correct intensity of a reflection to a material.
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.
Items to make reflective:
Spending time on these details can make the difference between a boring, flat image and an engaging, realistic one.
Use Section Planes for interior renderings
If your renderer supports section planes, you can create realistic renderings of the room itself with a camera position outside of the room.
Here are a few options you could choose from in order to solve this problem:
Use HDRi Skies to improve exterior renderings
One of the benefits of HDRi skies is the fact that the background image is in the shape of a dome, providing a full 360 degree background. This means that no matter what angle you are viewing your model from, there will always be a high quality background image. This also makes them valuable for scenes which contain reflection - reflective surfaces like this Camper, or windows.
And the separate lighting channel contained in the HDRi image provides better shadows and illumination than just the sun, or plain sky. This lighting information allows some parts of the sky to illuminate the scene more than other parts even though they have the save RGB (red, blue, and green) values and look identical.
Use HDRi Skies for:
Use 2 Pt Perspective for elevation changes
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.
When looking up or down at vertical surfaces, normal perspective will distort the vertical lines and cause them to be non-vertical.
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 the Light Balancer for quick lighting adjustments
Light Balancer isolates the effect of light sources on the final rendering, so that:
Use special Water Effects
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.
Use Self Glow for glowing objects
Self Glow illuminates a surface as if it had light shining on it, without actually making it a light.
Use Edge lines for better detail
SketchUp users are used to using edge lines for detail, but many Photorealistic renderers do not render edge lines.
If your renderer does not use edge lines, you can add them by saving a hidden-line image of the SketchUp model, and then merging it with the rendering in "multiply mode".
If your renderer does support edge lines, then you will have the added advantage that the edge lines will appear in reflections, as well as the rendering.
Use images and textures for faster rendering
(Not completed yet)
For background objects, and other objects for which 3D detail is not important, use images instead.
There is a free plugin for SketchUp - RpTreeMaker - which can be used to create tree images which can speed up your rendering time.
Use Panoramic Views to reveal entire model
A Panoramic image is created by rotating the camera while rendering to create a full 360 x 360 degree image. It works best with large interiors, or with exteriors which have a central point which let you view the full model.
You can create Panoramic Views by check the make Panoramic View check box on the Render Setup Tab dialog.
