What does visualization have to do with design? Quite a lot, actually. Many people overlook the importance of photorealistic rendering in the design and product development process, but it has some serious benefits. For example, when you perform a design review with an image created by photorealistic rendering, you can see exactly how the finished design will look. Are the materials right? How does the light reflect off of the product? Are aesthetics important, and if so, does everything look OK? Save yourself costly changes and rework by identifying issues early-on, long before materials are ordered or cut to specs.
NX 11 with the new Lightworks Iray+ rendering engine delivers progressive ray tracing in a fully integrated environment with Ray Traced Studio. This makes it easy to get great results, regardless of whether you’re a visualization expert or not. Materials look realistic right out of the box. There are even more materials and scenes to choose from when setting up your rendering.
The tip we will show today is for those of you who have already set up materials for Ray Traced Studio in NX 9 or NX 10. If you have used any of the System Materials in NX 9 or NX 10, we have provided the corresponding Iray+ System Materials in NX 11 that apply to your part automatically to replace the old ones. Iray+ materials are physically based, so you will have to apply new Iray+ materials to replace any materials that you have created on your own. This tutorial and video below will demonstrate the steps you must take in order to accomplish this. Let’s get started.
To begin, open the part to which you previously applied materials. In the example shown here, we have a drill part from NX 9. Notice an error message pops up to indicate that materials have been converted. Since this part was saved in Advanced Studio display, it opens in that display. You can see the new Iray+ materials, and there is a very noticeable color that shows any materials that have not been converted.
Open the Render tab and go into the Studio Task. Launch Ray Traced Studio; again, this is a different display with physically based rendering and global illumination. You can learn more about the various displays available to you in NX Rendering in our Introduction to NX 11 Rendering with Iray+ tutorial and video.
Open Studio Materials in the Part palette to see all materials in the part. Some materials, such as the chrome, have been successfully converted. There are two materials with the Iray+ texture. You will now see one way to quickly swap those out and apply new Iray+ materials in their place.
Select an object with the material applied, in this case the drill casing, and mouse button 3 to the options menu to pick Select All Objects with this Material. Now go to the new Iray+ based System Studio Materials palette and select the new Yellow Plastic. Follow the same process for the chuck. Select All Objects with this Material and chose the Aluminum.
Now the display and lighting are a bit brighter than we would like. So let’s change the scene to the new default with all lights properly set up.
See Patti Longwinter demonstrate these changes step-by-step in the NX Quick Tips video below! Thanks for watching and reading.
