Hello,
is there any installer available that installs just Houdini Engine without the main Houdini Application?
I am talking about the Engine including the libraries etc., not about the plugin here.

I am pretty sure there was one available because we have one for version 18.385, but I just don't remember where we got this and even after searching for quite a while I don’t find it anymore for a newer version (In our case we would now need version 18.460).

Hi,

We have deprecated/removed the old HEngine installer as it was problematic and not properly maintained.

Instead, you should use the regular installer, and use the command line arguments described in the HEngine docs:
https://www.sidefx.com/docs/hengine/_h_a_p_i__integration.html#HAPI_Integration_EngineInVersionControl [www.sidefx.com]

This will properly install Houdini with the minimum set of files required for Houdini Engine.

I see, that explains it.
Thank you!
