Join Paul F. Aubin for an in-depth discussion in this video Understanding the rendering process, part of Revit: Rendering.
- It's time to start rendering. So we've spent the last several chapters looking at the way to set up things. To configure our materials, to configure our lighting, and we're ready to actually begin creating some renderings. So in this movie, we're gonna look at the general overall process that's required to go through the rendering dialogue. And then in each of the subsequent movies in this chapter, we'll dig into each of the settings in a little bit more detail. So the first thing that's required to do a rendering is, you have to be in a 3D view. I'm in a 3D view currently, and so what you're looking for when you're in a 3D view is the presence of this small little teapot icon right there which would display the render dialogue.
Now you can also get to the render dialogue from the View tab, right here, using the "Render," button. Now if you're in a 3D view, the render dialogue will display, but if you're in a floor plan view such as Level I, it'll gray out here, and it will not be present here. So you must be in a 3D view before you can do any kind of rendering. So let's scroll down here, and I'm going to open up the Perspective at Entrance 3D view. And this is a perspective view that I've been working on and carefully configured.
And we're going to use this view to generate our rendering. So let's click the teapot icon. And that will display the Render dialogue. Now generally speaking, you typically work your way through this dialogue from top to bottom. With the exception of the Render button which is the last thing you want to click at the very top. So starting with "Quality," you would work down and then you would circle back and click Render when you're ready to go. Now I'm not gonna go through each of the settings in here right now. That'll be the subject of the next several movies. But I do want to just go ahead and set a few things. I'm gonna make sure that my quality setting is set to draft, I'm gonna do screen resolution, I'm gonna make sure that my lighting scheme is set to "Exterior Sun only," and I'll accept all the other defaults, and then we'll go ahead and click "Render." Now when the rendering process begins, initially, it will actually blank out the screen, it will all become black.
Don't worry that's normal, it's supposed to do that. And then you'll see this square kind of jumping around the screen in this sort of stochastic pattern. And that's the Mental Ray render engine processing each of the various areas within the rendering. Now, it appears that it does it kind of randomly. But when it's done you'll see that a rendering has generated. Now that was actually a fairly quick rendering to do because I only did draft and screen resolution. So it gave me a very quick result, and it's probably not something that I'm gonna want to put in my marketing brochure because as you can see, it doesn't look so great.
But in terms of getting a rough idea, if we're getting the result we want, the draft rendering can be an effective way to do a really quick easy test, and just kind of allow you to identify areas that may need your attention. In the coming movies we'll go through each of the areas of the rendering dialogue in a little bit more detail. But down here at the very bottom you'll notice that under "Display" it says "Show the model." Now if you click that, it will go back to displaying the model view and then that toggles to, "Show the rendering." And if you click it again it will keep the last rendering that you did, saved in memory, and you'll be able to toggle to that.
If you close the render dialogue, then it goes back to displaying the model. So that's the basic steps that you follow to generate a rendering. You've got to start in a 3D view, click the little teapot icon, configure the settings that you want within the render dialogue, and then you click "Render," to generate it. Now obviously, the higher quality that you do, and the more detailed your settings are, the rendering will take a little bit longer than the one that we just witnessed, but we'll go through all the details of that in many other related topics in the movies that follow.
