You can access the Sky lab by clicking on 'Sky & Fog' and then the little cloud icon to the right of that.
In the Sky Lab there are four tabs you can access at the top of the lab window:
Sun & Moon
IBL (Image based lighting)
- On the right of the window is a preview, some sun controls and memory dots. On the left are the various settings for that tab category. Each tab window is laid out in the same way.
- To access the settings if they are greyed out, click the round button next to the setting name.
- To adjust the settings click on the value fields and type in a new value or click on and drag the slider.
- Use the memory dots to save your settings or revert back to previous settings stored in them. Just click on one of the white empty dots to save your current settings.
- Click on the triangles next to the preview in each lab for options for how your scene is viewed in that preview (mine is set to Render in scene in the above image) or access to the Sky presets.
The terrain lab allows you to make changes to the appearance of the terrain.
To access the terrain lab either select the Edit palete and click the square icon I've labelled 1, or click on the 'E', labelled 2, which appears next to your terrain:
When you do so the following window will appear with four setting category windows:
You can select a variety of preset terrain types in the editing tools window by clicking on the arrow next to 'Fractal' and then adjust them further with the other settings in the editing tools window or by painting on the canvas, or you can click on the 'New' button and create a terrain from scratch yourself by again painting on the terrain canvas.
There is also an otpion under the 'Pictures' tab to load your own pictures to use to create terrains.
TIP - You can position each setting window , for example the terrain canvas, where you want on the screen. Just click on the top grey bar of the individual window, near where the setting title is and drag it to where you want it.
