Maxwell for Google SketchUp

 

Among rendering die-hards, the name “Maxwell” has long been synonymous with jaw-dropping realism. Maxwell Render’s makers have offered a SketchUp-to-Maxwell solution for a few years, but it required modelers to have access to Maxwell Render Suite—the full, standalone version. For SketchUppers on a budget (or who only need to make the occasional rendering), this wasn’t an ideal arrangement.

To accommodate more people, the folks behind Maxwell have just released something they’re calling Maxwell for Google SketchUp. It’s a dedicated photo-renderer, based on the venerable Maxwell rendering engine, that operates entirely inside of SketchUp. Best of all, it has the Big Three qualities going for it:

  • Cross-platform. It works on both Windows and Mac systems.
  • For both free and Pro. It works on both SketchUp and SketchUp Pro.
  • Two entry points. There are free and licensed versions available.

As you can see in this straightforward feature matrix, the free version allows you to render in Draft mode and limits your resulting image to a resolution of 800 pixels. The Licensed version adds Production mode (faster rendering of complex lighting) and increases your maximum output resolution to 1920 pixels. At only $95/75€, the paid version is a bit of a bargain.

If you’re looking for all the bells and whistles and extra pixels that Render Suite offers, the “bridge” plugin for sending your SketchUp model to R.S is still available. So really, SketchUp modelers who want Maxwell’s delicious, unbiased results have three options.

SketchUp: A better view of small spaces

When you’re modeling a small room, it can be a pain to see what’s inside. The problem is that the walls and ceiling get in the way. One solution is to lop off the ceiling and work in a top view, dollhouse-style. Other folks set up scenes from the interior corners and adjust their Field of View to something super-wide like 90 degrees.

Looking at a small interior space from the outside isn’t very rewarding. 

Deleting the ceiling and switching to a top view is useful, but fiddly. 

Standing in the corner and making your Field of View really wide is just weird. What are you—a housefly?

 

Both of the above techniques work—to a point. Personally, I think it’s like trying to read a book through a keyhole. By far my favorite method for working on small interiors is to make use of SketchUp’s ability to have faces with different materials on each side:

The face separating Susan and Sang is yellow on one side and green on the other. 

Creating a completely transparent material and painting the green side makes it see-through. 

The Entity Info dialog box shows that the selected face is yellow on the front and see-through on the back.

 

By painting the outward-facing surfaces with a see-through material—one whose opacity is set to 0%—I can see in from the outside. Super useful, super simple.

Here, I painted all of the outward-facing surfaces with a transparent material. Notice that the interior surfaces still look opaque? 

Orbiting around my model, I can see through all of the walls. I can even see through the floor.

SketchUp: How to Scaling imported raster images in LayOut

If you’ve ever inserted an aerial photo or an old scanned site plan into LayOut, you might have wanted to give it a specific scale on the page. My favorite technique for doing this uses the Clipping Mask feature.

Step 1
Choose File > Insert… to insert a raster image into your LayOut document. Find a known measurement somewhere on your image. This known measurement can be anything: a scale bar (if you’re lucky); the length of a fence or sidewalk; or even the roofline of a building. It’s important that you find something that’s relatively large and that whose length you already know. You’ll use this portion of the image as a “benchmark” to size the entire image to a specific scale.

In my example, a scale bar was included in my image; this makes it pretty easy to use as a benchmark.

 

Step 2
Figure out what scale you’d like to give your inserted image. Keep in mind how the scale will impact the size of the image and how that image will fit on your page.

For this image, I’m going to use 1” = 400’ (1:48) scale. This should fit nicely on an 8.5 x 11 sheet of paper.

 

Step 3
Create a rectangle around the “benchmark” portion of your image. Use the Rectangle tool to do this, and make sure it has no fill (so that you can see through it.)

This scale bar only goes to 300’, so I’m going to use the 0’ – 200’ as my benchmark. 200 is half of 400, which makes the mental math easier to do.

 

Step 4
Select both your rectangle and your image and choose Edit > Create Clipping Mask. Select the resulting crop and give it a visible stroke so you can see its boundary.

I color the clipping mask to make its border easier to see.

 

Step 5
Somewhere on your page, use the Line tool to draw a line whose length corresponds to the scale of the image you’re working on.

To draw a line, click to start drawing, move your cursor in the direction you want the line to go, type the length you want and hit Enter.

Since I want a scale of 1” = 400’, and my “benchmark” is 200’ feet long, I draw a horizontal line which is one-half inch long (1 inch divided by 2).

 

Step 6
Move your benchmark, snapping its lower-left corner to the left endpoint of your line. Be sure that Object Snap (Arrange > Object Snap) is turned on, or snapping won’t work properly.

I snap my benchmark to the left endpoint of my line.

 

Step 7
Scale your benchmark so that it’s the same length as the line. With your benchmark selected, hold down the Shift key and scale it until it snaps to the right endpoint of your line. As long as you hold down Shift, your selection should scale proportionately.

I scale my benchmark to the right until it aligns and snaps to the end of my line.

 

Step 8
Select the benchmark and choose Edit > Release Clipping Mask. Delete the rectangle from Step 3, and the line you drew in Step 5, and you’re done. Voilà! You’ve set your image to a specific scale.

Image set at 1” = 400’ (1:48) scale and positioned on a letter-sized landscape sheet.

 

This may seem like a lot of steps but it’s actually pretty simple. Have a look at the following silent movie to see how it’s done.

SketchUp: The textures

If you’re into such noble pursuits as geo-modeling or photo-realistic rendering, there’s a good chance that you spend a ridiculous amount of time hunting for photo-textures online. Flickr and other photo sharing sites are goldmines for content, but who has time to compile a folder of bookmarks that point to the best ones?

Our friend John Pacyga, apparently. He’s just posted a long list of his favorite texture sources — for both SketchUp and Photoshop. Some are free, some have Creative Commons licenses, and some cost money, but all are worth browsing. Set aside some time, though; this kind of thing is addictive.

If you’ve found a seamless texture (one that can repeat attractively when you paint it on a surface), here’s how you load it into SketchUp:

I found the rock texture in the screenshots above on lee.ponzu’s Flickr Textures set. Want to make your own seamless texture images? These tutorials on YouTube are a good place to start.

SketchUp: Speed Up Using Fast Styles

You might not realize that the display settings you choose to apply to your models can affect SketchUp’s speed and general responsiveness. Turning on fancy edge effects and other doodads will slow you down when your model gets big.

When you’re working on a big model, you want to make sure that you’re using a style whose Edge Settings panel looks like the one in the image below. Everything but “Edges” should be turned off.

The Face Settings panel is where you can choose not to display Transparency. When Transparency is turned on, SketchUp has to redraw your model on the screen several times—each time you change your viewpoint. If you don’t need to see through your windows just now, opt to temporarily view these faces without transparency.

The Background Settings panel is handy for turning off Sky and Ground, both of which cause your computer to do extra thinking while you’re working.

Unless you absolutely need them, you should use the checkbox in the Watermark Settings panel to turn off Watermarks.

The only toggles in the Modeling Settings panel you really need to worry about are the ones for Hidden Geometry and Section Planes. Obviously, you shouldn’t have wither of these displayed if speed is what you’re aiming for.


Once you’ve configured your own fast style, you should save it. Just give it a new name (I suggest “Fast Style”), hit Enter, and click the Create New Style button in the Styles Browser. You new style is saved in the “In Model” collection of styles, which is only associated with the model you’re currently working on.

Incidentally, almost all of the choices in SketchUp’s Default Styles collection are so-called “Fast styles” — their Edge Display settings are already configured for speed. Choosing any one of these styles will switch off extraneous effects.

Make a Fast Scene

True SketchUp whizzes invariably go one step further and add a special “Fast” scene that they can activate whenever they need to. Rather than having to mess with the Styles Browser every time they want to activate their Fast Style, they just click a scene tab at the top of the modeling window. This Fast scene is usually set up to do three things: Switch to a Fast style, turn off Shadows, and turn off Fog.

Follow these steps to add a Fast scene to your model:

  1. Apply a Fast style to your model by choosing it from the Style Browser’s Select tab.
  2. Make sure Shadows and Fog are both turned off. These toggles are in the View menu.
  3. Choose Window > Scenes to open the Scenes Manager.
  4. Expand the Scenes Manager by clicking the Show Details button in the upper right corner.
  5. Click the Add Scene button to add a new scene to your model.
  6. Rename your new scene “Fast” (or something similarly descriptive) and hit Enter on your keyboard.
  7. Make sure that only the “Style and Fog” and “Shadow Settings” checkboxes are selected in the Properties to Save section of the Scenes Manager.
