Since Corona 1.5, advanced system settings, such as a number of threads override, autosave options, VFB settings, and more, are system-wide rather than saved with a scene (they are stored as global settings on the specific computer, rather than in each specific scene file), and all those settings are conveniently placed in one dialogue. To find them, go to Render Setup > System, and then click on the "System Settings" button:
Some Use Case Scenarios
1. Sharing Scenes Across Different Systems
As settings are saved per system, sharing files within a team of artists is very easy. For example: If one team member prefers a different number of threads for IR or autosave interval, it doesn't change when they access a shared scene on their machine. The scene adapts to their settings, not the other way around.
2. Interactive Rendering Settings
Interactive rendering is important for making on-the-fly adjustments. By tweaking these settings, users can optimize the real-time feedback quality and speed. For example: When working on complex interior scenes where lighting and material adjustments are frequent, having faster, a bit reduced quality feedback, can speed up the decision-making process during rendering.
3. Output Autosave Features
When rendering for long hours, due to unforeseen issues like power outages, you can loose your renderings. The autosave feature can keep your renders safe by automatically saving your renders at set intervals.
4. Out-of-Core Textures Feature
When rendering a complex scene with a lot of high-res textures, it is important that you do not run of memory. Using the out-of-core option in Corona lightens the load on memory resources. For example, if you have a very big city scene, buildings close to camera can use high-quality images, while far-away buildings can use lower-quality images without compromising the final render. Out-of-Core texture feature in Corona helps your make these smart adjustments, so you don't run out of memory. You can find the settings for the out-of-core textures feature in the System Settings.
Corona System Settings is more than just a list of preferences. By understanding and utilizing them based on specific scenarios, artists can streamline their workflow, optimize rendering speed, and ensure consistent output across different systems.
