Similar to blueprint class BP_DemoRoom，There is something inside the viewport，But there is no static mesh on the right side。Did you find that the instanced static mesh component written in the blueprint was used? Is this completely implemented using blueprint nodes one by one? Did you still use any editor functions? If using the blueprint function，How to align the node positions？Are there any related videos available?Thanks?

It’s a level instance, hence the little map icon
If you have a look at the levels in the project, one of them is this collection of meshes.
Epic has done quite a lot in the area recently, but I haven’t really seen any clear summary or docs anywhere. It’s something related to level instances and packed level actors.

thaks,I have learned some new knowledge，But I opened the blueprint created using ‘Create Packaged Levl Actor’，I check the inheritance relationship。The blueprint created by ‘Create Packaged Levl Actor’ is
But Content Examples blueprint “BP_DemoRoom”,the inheritance relationship
I checked the function and found that
But the blueprint created by ‘Create Packaged Levl Actor’ is not done anything。
I downloaded the project from “Epic Games Launcher”。
Did I not perform any operation that resulted in a different outcome?

Yes, it’s not exactly the same, is it?
I’m not quite sure what procedure was used for the ‘actor’ version, I’m afraid

Are you sure the room blueprint has done nothing?
because I see there’s a lot functions on the left side,they look very like something adding components on runtime.
the construct script called the redraw function.hmm…it’s suspicious,might be the sequence entry…what’s inside it?
I didn’t download the project.just to remind you ,in case you didn’t notice them. better to check them out.
hope it useful.
Thanks!I check the function “Redraw”,I found that it did a lot of things，I found that it used another function “Create Instances”。
I check the function “Create Instances”,I found that it has been used a lot “Instanced Static Mesh Component”。
I check the function “Redraw”,I also found that it used another function “Create Room”。
I check the function “Create Room”,I have found that there are many calculations related to location and the like。
What I want to consult is whether these program logics that are completely based on blueprints are written using one node after another? Does it use some of the built-in functions of blueprints or editors? Otherwise, how can the positions of these coordinates be aligned? Did it use any visual editor features?
