This feature creates a transparent lamp beam with a pattern to emulate light passing through a smoky or foggy room.

You can define a visible light beam on the spot-light creation wizard.

External Rendering exports the model to a file, and then renders the file in a separate process.

This allows you to make changes to the SketchUp model wihtout having to wait for the rendering to complete

Create PDF is a feature to create an interactive 3D PDF Presentation using your model and your Rendered Image.

Both the 3D Model and the Rendered Image are displayed on the first page of the PDF file, with a set of buttons for the user to choose between the two.

How to use it

  1. Render your model, and use the Save Image icon on the toolbar to load the Save Image Wizard. Revit save image button.png
  2. Select Create PDF from the bottom of the Wizard.
  3. Enter the PDF settings on the next dialog.

Make Tileable takes a material texture which does not repeat properly and make it repeatable, or tileable, either by re-blending it in on itself, of by mirroring it in the X and Y direction.

How to use it

  1. You place the high-quality, but non tiled, material in SketchUp.
  2. You right click on a face with the material, and select "Make Tileable"
  3. We load a wizard which shows a tiled example of the material on the SketchUp face, and what it will look like using one of two tiling methods.

nXt Path Tracer is a new rendering engine for IRender nXt.

You can enable the Path Tracer rendering engine on the Render Setup Tab

  • Comparison to nXt Packet Mode

nXt Packet Mode processes packets of rays, while nXt Path Tracer processes individual light paths.

Because of some shortcuts, such as Daylight Portals, and other aspects of the rendering process, nXt Packet Mode create a usable image in fewer passes. nXt Path Tracer often requires more passes before the image gets smooth.

Volumetric Fog is a feature in IRender nXt incorporate the effects of light reflecting from or being blocked by fog or haze.


How to use it

  1. Download the latest version of IRender nXt
  2. Use Fog Setup Tab to setup parameters
  3. See: Volumetric Fog for examples and advice on settings.

Batch Rendering is a rendering mode which exports the model to a file, and then renders the file in a separate process.

It has 3 main uses and benefits.

  1. Large Models - Models which are too large to render directly from SketchUp can be rendered in batch mode.
  2. Animation - Batch mode is used for animation, because animations need to load and reload the model when there are layer changes, and because animations typically take a long time to render.
  3. Network Rendering - The entire folder containing the rendering information and files can be accessed across a network, or copied to a thumb drive or another machine and used to render the model.
