By enabling edge lines in the advanced section of the Template Material dialog box, you are able to see edges in renderings.
- It's possible to render the edges of Geometry in Twilight. To experience this, let's go to scene seven, which is a close-up of this Falling Water Lego set that I found in the 3D warehouse. Let's start by making a test render using the low preset at a small render size. I'll lock the aspect ratio, and change the width to 640. That automatically inputs the height 360 to maintain the 16:9 aspect ratio.
I'll make a rendering. Now edged faces are useful in situations where you want to delineate separations in plane. For example, in this Lego set or in a kitchen cabinets, or in reveals in office furniture, or in walls where you have these grooves that exist. It's good for situations where you don't want to explicitly model the separations, but you want to see them in the rending. So here we have some of the rendering coming in.
I'm just going to stop it. And in this vertical surface here, we perceive it as a single surface, but in actuality this is composed of many separate objects, namely the Lego bricks. I'd like to perceive that in the render. To do so, let's go into the template material dialogue, and sample the material off of this object. That brings up the Lego one material. Open up Advanced and enable edge lines.
I want the edges to appear only when we have changes in plane. So let's change this to 90 degrees, and then the edge line width I'll leave at the default 1 millimeter. And let's render that, and see how it looks. I suspect that these edges might appear to be too thick because the Lego bricks after all are very small. They're probably smaller than a centimeter. So the 1 millimeter edge might be a bit heavy-handed. We'll just have to see.
Yes, I have to say that's too thick in this context. But you do have the ability to vary the edge width. So in some cases you might want the reveal to be 20 millimeters wide, and you can do that. In this case, because we're dealing with a small model, I'll decrease this value to a smaller number. Let's say it's the minimum value. Now it's really not going to render it at 1,000th of a millimeter, but we're going to encounter the lower end, the limit of what Twilight can render.
It's going to show us the very thinnest edge that it can. Let's see if that's acceptable here. Yes, I have to say it looks good, and now we're able to perceive the individual Lego bricks that make up this model. I'll stop the rendering. Note that you can't see edges on these green trees here. To do that, you have to go and select the other Lego materials, Lego two through six, and enable edge lines, and change these values to what we had used previously.
But I'll leave that up to you to go ahead and make those changes to the materials. You can also go up to the tools menu, and you can turn edge lines on in all template materials, or off in all template materials. So this is kind of a global feature that turns on this feature in all the materials. So be careful with that. In this case, I don't want to turn edges on everywhere, I just want it to be visible in the Lego set.
