Advanced Rendering Settings

It can be so easy to get that basic rendering from your model, but so hard to get a perfect photo-realistic image. The first step is upping the size and quality level of the render window. Of course there’s a relationship between image size, quality level, and file size, just as in Revit: the more of the first two you have, the bigger the last one will be.

Big Picture: Consider how you plan to display the image–printing will always take more pixels per inch than web-, screen-, or projector-based images. Use BMP format rather than JPEG, as this preserves more of the rendering.

Configuring IRender nXt for High-Quality Images 

1. Open your model and choose Save As from the pull-down menu. Name the new one Copy for Rendering or something clever like that, so you don’t accidentally mess up the original.

2. Choose the scene or view you’d like to render.

3. Click on the Options button to configure for a test rendering

4. Choose settings based partly on how confident you are of the model settings, and how much time you have.

5. Check on the Lighting tab to make sure you’re set up for an interior rendering.

6. The AccuRender settings are under the Special tab, and look the same as in Revit.

7. Set options for edge lines, blurriness, and number of bounces, and click OK when you’re feeling composed.

8. Click the green Render button.

9. A preview window will pop up with a quick, sloppy rendering. Click the green Render button again to continue.

10. IRender nXt will trace up the screen over and over again until the rendering is complete, just like in Revit.

11. Once the image has rendered, click the Tone Operator–it looks the same as the Adjust dialog box for a Revit rendering. Adjust brightness, contrast, and indirect lighting to taste. 

12. Save the rendered image to your disk–JPEG and PNG are the only formats available.

These rendered views are not connected with the original model, and once you close the IRender nXt window, you’ll lose an unsaved rendering. IRender nXt can also perform a batch render, where all of your scenes can be rendered and saved at once. This will certainly take a while, but it will run automatically, so 

start it on a Friday. 

Note :  So it didn’t work for you, did it? If you got an error message like, “out of memory,” try this: make sure you’re working on a COPY of your project. In that copy, delete everything that doesn’t show up in your view (leave things that show up in the mirror, though). Purge the drawing again. You could even try restarting your computer at this point–a good idea if you’ve been running Revit and SketchUp and Photoshop Elements and AIM and watching videos on YouTube all at the same time. Anyway, try rendering again, and it should work.
