Help With Creating Custom Asset Types in C++

I have been looking into creating some custom asset types in UE and wanted to experiment a bit with it. However, so far I have found very limiting info on the subject so I am gonna ask here.

I’d like to create an asset type that has a blueprint editor graph and a custom one (that I will make for it).

  • as for the blueprint editor, I really only need to use the event graph, nothing else (i.e. the left panel for adding components should not be present)

I am a little bit familiar with how the custom graph is being set, as well as how the basic infrastructure looks like. Now what I would really like to know is the process to get there, as in what classes are absolutely necessary to make this going.

So far this is what I have gathered, correct me if I am wrong:

  1. Base class for whatever will hold the data or anything else relevant to the core of the custom asset (i.e. BaseQuest, BaseDialogue etc…)

  2. FAssetTypeActions_Blueprint class so that the asset actually shows in the content browser

  • note with this I still have linking errors for an unknown reason, anytime I set my class to inherit from this one the code just won’t compile, still haven’t found a solution so if you do know please write it down

  1. UBlueprint class for the asset that will be created

  2. UFactory that will perform the creation of the asset

After this I am really confused. What I was trying to do is to find plugins that use custom assets and to reverse-engineer them but it was very overwhelming. For once, I cannot seem to find in which class is the custom graph even set in, all I could find was classes about it. I am aware of the connection drawing policy, style, basic node, root node and the schema classes for it. How would I go about just getting a basic graph in my asset?

  • for starters it would be amazing just to get the basic design of the asset so I can see it, after which I will look into customizing it fully

Any resources that you may know of, please link it in the comments, so far I found like 2 posts in total about custom asset types and none of them feature either a custom graph or even creation of a UBlueprint.
