you’d need to examine the source by adding a debugger statement to three.module.js;
https://github.com/nicerapp/nicerapp_v2/blob/2777b7be948e62852b89d30956cebf5962095fbd/nicerapp/3rd-party/3D/libs/three.js/build/three.module.js#L41262
then you’d inspect data.image in the debugger, and figure out how to use that data.
sorry, but that’s as far as my current knowledge about the inner workings of threejs goes at the moment.
maybe someone else can be of more assistance…
