The creators of Katana were nice enough to provide us with a built-in test mesh. Everybody likes ponies, so they made it easy to get one. Choose Help > I want a pony.
CameraCreatenode had the blue highlight clicked on, the only thing that would be in the Scene Graph would be the camera. If the
Mergenode has it, both the camera and the pony geometry are present. To set this click the left square or press V on the keyboard while hovering over the node. The green highlight indicates which node is being edited, and its parameters show up in the Parameters tab. To set this click the right square or press E while hovering over the node.
RenderSettingsnode, and change renderer to Arnold:
If Arnold is not an option in the renderer drop down, your
KATANA_RESOURCES environment variable probably isn't pointed to the Arnold render resources, or Arnold itself is not available. Go back to the installation section to see how those are typically set up.
Rendernode, and then right-click the node to get a small contextual menu. Select Preview Render. Now, switch to the Monitor tab (at the top-left of the window, near the Node Graph tab you already see) to see the render actually going. Hit the Home key on your keyboard to get it to its real size, and you should see the pony's hooves:
You can see all of the console output from Arnold as it renders in the Render Log tab. When there are issues with the render, this is the first place you should look.
The pony's feet are not that interesting, so now we have two tasks: make the pony smooth-shaded, and position the camera. For the first, go to the Viewer tab, and switch to the camera created with our
CameraCreate node by clicking on the perspShape text. It will have a camera icon next to it, named ../camera. Then, try moving the camera around with the mouse while holding the following buttons:
Try to get the pony centered in the view from various angles, and then zoom out and orient it something like this:
.You may drag the node (after it is placed) over the connection between the pony node and the
Mergenode to insert it along that connection:
Rendernode, and right-click it to run the Preview Render again. Switch to the Monitor tab, and now you should have something like this:
Now go to Part 2 to add shader networks and lights.
