If a project gets heavy in loading, because of large meshes and textures for example, it seems that the OnOpen node doesn’t trigger, or maybe it triggers too early. I use it for caching data.
Is there something to make sure that things get cached (Region) when everything is properly loaded ?
Meshes and Textures get loaded asynchronously and they have output pins indicating when they finished loading. so there is no global idea of when things have finished loading. you’d have to collect the “Is Loaded” info of all sources that you want to wait for and decide yourself.
