Corona Renderer 1.4: A Guide to Color Mapping Operations and Temperature Shifts

In the latest update, Corona Renderer 1.5, a change was made to the color mapping operations that has caused some confusion among users who are used to working with the older versions of Corona. Specifically, this change affects scenes saved in Corona 1.5 and opened in newer versions, such as Corona 1.5.1.

'Corona Renderer 1.4' If a scene is detected to have been saved in Corona 1.5, an error message will appear, allowing users to switch to the correct order of color mapping operations. This change should result in the same color balance as when rendered in older versions of Corona.

One notable issue with this change is that scenes saved with a warm color temperature (reddish) may become even warmer (more reddish) in Corona 1.5, while those saved with a cold color temperature (blueish) may become even colder. This results in a shifted color temperature of the rendered image compared to the output produced by Corona Renderer 1.4 or older.

Corona Renderer 1.5.1 (hotfix 1) was released to address this issue, and users are advised to switch to the new order of color mapping operations and save their scene to get more expected behavior.

In summary, if you encounter a scene that has been saved in Corona 1.5 and is now being rendered with Corona 1.5.1 or newer, be sure to switch to the new order of color mapping operations and save your scene to ensure accurate color temperature representation.

As an example, take a look at this image rendered in Corona 1.5: . The blue tint indicates that the color temperature has shifted due to the incorrect order of color mapping operations. By switching to the new order, you can achieve a more accurate rendering with the correct color balance.

In conclusion, while the changes made in Corona Renderer 1.5 may cause some initial confusion, they ultimately improve the accuracy and consistency of the rendering process. By understanding how these changes affect your scenes, you can ensure that your renders meet your expectations and deliver high-quality results.
