Hi everyone. I made a script to stop the constant digging through Corona’s render settings just to tweak environment maps. The Corona Single/Multi HDRI Manager (v2.0) gives you a dockable panel to load and manage up to 10 HDRIs directly from a folder list with thumbnail previews.
The biggest workflow saver is the interactive viewport rotation, which uses visual dome helpers to rotate your lighting in real time. It also features individual color correction, vertical tilt (V Offset), a one-click Isolate button to solo any map, and proper shadow blurring via standard BitmapTextures.
