Loading one HDA multiple times very slow 2021年1月15日10:17

This is directly related to the amount of nodes you are loading and the operations each node is performing on initialization.

When Houdini opens a scene, it caches all the nodes in the scene to memory and performs certain checks on the data.
It also bloats your memory footprint.


Every copy of a HDA gets this treatment, and as far as I'm aware you can't instance a node.

So either design your HDA to allow multiple birds to be spawned at once, or perhaps cache your data and then load it using a lightweight asset.

I'm not fully informed on all of Houdini's capabilities so I might missing more substantial that can help you.

Python 3 - printing to console not working 2021年1月15日10:12

+1 on this topic.

I just updated to Houdini 18.5 and also just noticed this.
I make a lot of use of this to debug, or provide feedback to the user. having to open the python shell to get information is annoying.

I'd like it to be able to output to the console on print like it has been able to.

Houdini Engine for Unreal - Version 2 2020年12月4日4:45

Will V2 get access to fproperty attributes on unreal instances, so we can set different material instance settings per instance without having to instantiate entirely different meshes? at least If I understand it correctly the newest version of unreal allows for this.
