NX 11 Rendering - Iray+ Material Operations


NX 11 features the new Lightworks Iray+ rendering engine based on NVIDIA Iray progressive, real-time ray tracing. Fully integrated with NX Ray Traced Studio, the new Iray+ rendering engine is easier than ever to use. There is even an expanded library of scenes and materials to help you set up photorealistic images for use in design reviews, product presentations, and marketing materials.


If you did not see our previous NX Quick Tip tutorials on rendering in NX 11 with Iray+, then be sure to go back and check those out. The introduction to NX 11 Rendering with Iray+ walks you through the user interface and a basic workflow to achieve various rendering results. The Depth of Field tip explains how to use this effect to highlight specific product features you want to call out, or to add an additional level of realism to your images.


Today, though, we will be taking a look at how to perform two different material operations: material swap and material editing.

To begin, open a part in NX 11. In the example shown here, we have a drill to which we previously applied Iray+ materials. There is an information message that lets us know all materials have been successfully converted. If you need instructions on how to convert materials from a previous version of NX to NX 11, please see our previous tutorial and video.


Advanced Studio and Ray Traced Studio are currently displayed. Go into the Rendering tab and open Studio Task. NX Rendering Product Manager, Patti Longwinter, always sets up her rendering in the Studio Task environment.


Studio Materials in the Part Palette includes already applied materials. Notice these can be seen in both the Advanced Studio photorealistic simulation mode as well as the physically based Iray+ Ray Traced Studio mode.

First, let’s take a look at the drill housing with the new blue plastic material that was created previously. Select an object with the red material, mouse button 3 to open the object commands, and pick Select All Objects with this Material. Now choose the blue plastic to apply it to the drill housing.


You can review your changes and even show a customer or colleague this new material variation. But say you wanted to see this plastic in a darker shade of blue. To do this, go to Studio Materials in the Part Palette, MB3 over the blue plastic material, and choose Edit.

The new Iray+ materials have a Base layer and any number of additional layers. You need only change the color of the Base Matte layer. Choose the color you would like and hit OK to apply the changes.

Let’s say you want to reuse this material on other designs in the future. In NX 11, you now have the option to save the material to the System Studio Materials palette. Save it to the folder corresponding to the palette folder. Now when you go back in, you see that the material is there to reuse at a later date.
