I also encountered this issue. I have the latest version of nwjs v0.54.0 installed from here: https://www.construct.net/en/construct-2/nwjs, but the 3D layer is black when loading. I updated the Baby 3D itself to version 0.954 over the old 0.93, but that didn't help. There is only one third-party plugin in the project itself, and removing it didn't help. Does it make sense to check all the plugins that are installed in C2 itself? Can you show me the configuration settings for nwjs?
