I found the error, I'll leave my solution here in case you need to help someone. in my code I forgot to activate the post processing function.

Answer 2

I assume that you are using web-ifc-viewer. Just to give some more insight on this, the postproduction of web-ifc-viewer is an additional HTML elements that is displayed on top of the Three.js canvas.

For performance reasons, this layer only gets updated when the user stops moving the camera. When you go into floorplan mode, you need to disable the postproduction manually. This can be done like this:

ifcViewer.context.postProduction.active = false;

This also means that when you go back to 3D mode, you probably need to activate it again. FYI, you can also update the postproduction on demand:

ifcViewer.context.postProduction.update();
