i am using corona 12 and max 2024, both licensed not cracked programs and suddenly this has happened. All the reflections changed and i have no idea why. when i merge everything into new scene the problem remains, when i copied just for example, pillow and chair it rendered correctly. What could be the problem?
This can happen when the camera is close to an object with a refractive/volumetric material. Corona then assumes that the camera is inside that object and this affects the way things like reflections/reflections are computed (IOR). There could be different solutions depending on the case:
- moving the camera further away from the problematic object
- (re)moving the problematic object
- making sure that all refractive materials are capped (they are not open geometry, or a plane with no thickness)
- checking the scene for mistakes - for example, perhaps there are window panes with no thickness in the scene using refractive materials
Another thing that most likely would work is updating to a newer Corona version, where detection whether the camera is inside volume is improved.
ah thank yuo, yes camera is very close to the window, but that happened suddenly, i will try on monday when i get back to work. thank you for your reply, this bug has never happened to me before and i have been using corona for over 10 years.
