Required modules for GUI Holographic Buttons (Shader not found)

Greetings all! We have a few holographic buttons in our project that have stopped appearing since we switched to using npm modules to import Babylon. I’ve attached the image of the error that appears, but it seems to be missing a shader that it expects, the one that provides the background for the buttons.

I build the project locally and the 404 error I get is:
http://localhost:8080/src/Shaders/fluent.vertex.fx 404 (Not Found)

Is there another module besides the GUI module? I’m also importing Materials but that didn’t seem to make a difference. I’ve tried to manually import the required Shaders but haven’t had any luck.

missing shader

ohhh, looking into the code, it should be ok :frowning: Could you share a simple repro on github ? I ll have a look ASAP

Hmm, it’s a bit tricky to extract from current project in the state that it’s in but I will do the best I can. In the meantime here’s a look at that error a bit expanded in case that might help.

yup it should definitely not happen :frowning: Just a simple scene with a single button might be enough to repro ?
