This is part two of the wine glass tutorial. Before attempting it, you should have completed part one. This exercise is based on the Blender Wine Glass Tutorial 2 but updated for the current version of Blender.
A Scene
We're going to add elements to make this a full scene.
- Make sure the whole wine glass is selected, and click the 'Material' icon on the right-hand properties pane. Choose 'Add new' and switch the surface to 'Glass BSDF'.
- From the 'Add' menu in top left, select 'Mesh' -> 'Plane'. Move the plane down so that the glass sits just upon it, and scale it in XY so that it forms a surface.
- Select the 'Material' icon on the right-hand properties pane again. Choose 'Add new' and switch the surface to 'Diffuse BSDF'. Pick an orange color. To see a preview rendering of this color, switch to 'Viewport Shading' at the top right.
- We're going to add a large light behind the camera. Zoom out
until you can see the camera, and add a plane just behind it as shown
below. From the material property tab, add a new material and select
'Emission' for the type. This will make it a light source. (Unlike
Three.js, in Blender emissive surfaces do cast light on other
objects.)
- The next step is to set the view from our camera. Adjust the viewport until the scene looks the way you like, and then select 'Align Active Camera to View' under 'Align View' in the 'View' menu. You'll see a box showing the portion of the scene that will actually be visible to the camera. If it doesn't look the way you want, adjust the viewport accordingly and try again.
- Save your file if you haven't done so already. Blender sometimes crashes, so it is good to get in the habit of making frequent saves. Also keep backup files of your work when you hit a checkpoint.
- Make a second wine glass. Right-click the first and select 'Duplicate Objects', then move it to a new position next to the first (restrict movement to just one axis so that it stays sitting on the plane.)
- Now choose the 'Render Properties' icon on the right-hand side (looks like a camera). Select 'Cycles' as the render engine. Now from the 'Render' menu at the top menu bar, choose 'Render Image'. A new window will open, and your scene will start to render. This is a high-quality ray tracing, so it will take quite a long time and may use a lot of processing power. You can see the progress report in a little text line at the top. If the final result looks grainy even when finished, try adding extra samples to the rendering mode (double, or quadruple). If your computer has a graphics processing unit (GPU), you can possibly speed up the process by selecting that for the 'Device'.
