Internal Rendering 21
Rendering internally is the easiest way to turn your 3D scene into an image. It has minimal controls and utilizes several existing Blender render options that will be familiar to any existing user.
- Render, Start IPR and Render Animation: These control buttons are pretty self explanatory. Choosing render will start the rendering process. Start IPR will launch an interactive render session, where materials and lighting can be changed in realtime. Render Animation will render out each frame between the Start Frame and End Frame settings.
- Display: These options are the same ones used for Cycles or BI renders, and it determines how the ui changes to accomodate the in progress render.
- Render To: This option determines where the render output is sent. If it is Blender then the render results will be displayed in the image editor. Choosing IT will send the output to the IT viewer (which will launch automatically). In both cases the render progression will be displayed in the Blender info header.
- Only Render Selected: This option will render the objects that are currently selected in the 3D View. This is a quick way of previewing part of a scene without having to manage render visibility in the scene outliner.
-
Denoise Post-Process: This enables the Renderman denoiser, which is run on the image after rendering has finished. Once the denoiser has finished it's processing, the final clean image will be loaded into either the image editor or the IT viewer.
- Internal rendering is the most convenient rendering option for users, however, it is also the least configurable and is not ideal for more complex render tasks.
- The denoiser is powerful but it is not a silver bullet for removing noise. If the image it is fed is too grainy, you will see splotchy artifacts in the final output. Best practice is to render the image to an almost noise free state and then use the denoiser to remove the last traces for a clean, detailed image. Also keep in mind that depending on your delivery format, the denoiser may not even be useful. Cinema visual effects often benefit from some slight noise, as it emulates film grain. Animated features, however, typically need to be noise free, and this is a great place to use the denoiser
