Shaderlight – From SketchUp Model to Finished Render
By Kate Marshall
The Shaderlight plug-in for SketchUp lets you render great images from inside Google SketchUp. As a fully integrated plug-in, Shaderlight lets you see your image ‘develop’ as you work, interactively updating every time a change is made to any SketchUp scene. As this is the beta release, the full release will be available this September (2010) and will contain real-time MELT changes. What this means is you will be able to edit Materials, Environment, Lights and Textures in real-time without having to re-render. This tutorial is a great way to get started with Shaderlight.
This tutorial shows you how to get from SketchUp model to finished render in five easy steps using the new Shaderlight for SketchUp Beta plug-in. With no complicated settings to master, any SketchUp user can achieve great results with a minimum amount of fuss.
1. Starting your render
With Shaderlight installed, you will see three buttons appear in your SketchUp window, start render, material editor and render settings. Click on the camera to start your Shaderlight render and you can see it begin to progressively refine in the Shaderlight render window.
Shaderlight for SketchUp fully supports SketchUp’s material library so as this model already has some SketchUp materials applied, Shaderlight automatically converts them in to fully textured Shaderlight materials as well as applying automatic lighting using SketchUp sun, sky and shadow controls.
The Shaderlight settings menu controls render resolution and render quality. The Shaderlight window will show your render at the resolution specified and quality setting.
We’re rendering our image at 1280 x 720 and at a medium quality setting for quick results. We do recommend that you choose a medium quality setting when setting up your scene and then when you’re happy, increase the quality for a production ready image.
With auto updates switched on, the Shaderlight render automatically updates every time a change is made to your SketchUp scene.
2. Applying Materials
Apply materials to your model using the SketchUp paint bucket, just as you always do. You can then use the Shaderlight Material Editor to add different finishes to all your “in model” materials. To make it even easier, Shaderlight already sets “Auto” finishes to all of the materials in the Google SketchUp library so you don’t have to do a thing to get great results.
We’ve applied a brick finish to a couple of the walls in this model which, with bump maps automatically applied, adds subtle relief to the brick texture for increased realism.
With the auto material applied, you can fine tune your material finish by using the simple drop-downs in the Shaderlight material editor. The Shaderlight material ball will show the finish you’ve selected in real time.
So that we can see inside our model through the glass in this scene, we’ve selected the translucent glass material from the SketchUp material library and then adjusted the finish by selecting shiny and polished from the drop down menu to add some reflection to the glass.
Using the left mouse button and scroll wheel to zoom and pan around our image, we can focus on specific areas of the render to make sure we’re happy with the settings applied.
3. Setting Lighting
The lighting and grey SketchUp background need to be adjusted so that any reflective materials such as the windows in this scene have something to reflect.
The beta version currently supports SU sun and sky and HDR lighting however more advanced lighting features will be included in the full release of Shaderlight for SketchUp later this year.
In the lighting section of the settings menu you can choose from a selection of preset HDR’s or add your own. We’ve chosen ‘Golf Course Evening’ for our render to create a quick outdoor sunset effect. As we rotate the HDR using the position control on the settings menu you will see that the shadows will automatically update.
The beauty of Shaderlight is that you don’t have to wait for your render to finish or re-export your scene if you want to change anything. You can continue to make adjustments to any part of your scene and your Shaderlight render will automatically update.
4. Adding a Background
Using the render settings menu you can choose to a background for your image.
With options for SketchUp background color, IBL environment or custom background it’s simple to apply a background image to your render. For our beach house image we’ve applied a nice sunset image. We can then re-size and position our model in the scene and it will interactively update until we’re happy with the final shot.
5. Final Render
With our render complete we can zoom in to 100% to see our final image at full resolution.
