I am new to Houdini and fascinated with this unique tool. As my first real job with Houdini I create modular elements for a virtual museum. The user should be able to adapt these digital assets with sliders in a web browser (similar to the HDA interaction in UE4), send his wishes to the server and get the game ready element sent back. Any hint how to use a HDA in a web environment would make me very happy.

there is some info here, not sure how relevant it still is

I did something similar, you can use pyhyon in Houdini to setup a websocket server and use javascript in a browser to send command to it. You'll have to account for multiple simultaneous users and some other gotchas I'll leave for your entertainment

Thanks very much to Tomas and Jonathan for your kind guidance!
