By checking the compatibility of the PhotoVideoRendering-1.3 plug-in with SweetHome3D-5.5, I get an error after integrating the PhotoRenderer file update.
Error message: "The method getPieceOfFurnitureNormalizedModelTransformation (HomePieceOfFurniture, Node) from the type ModelManager is not visible".
I guessed you would need getPieceOfFurnitureNormalizedModelTransformation, made it public during half an hour, and finally changed my mind because I didn't want that a method with such parameters be part of the API.
Just copy / paste it in your own code.
