How to spawn objects and change conents in the scene.

[a2a4]

What platform am I on? What are my system specifications? Do I meet the minimum specifications for the Unreal Engine?

Platform: Ubuntu 20.04

What commit of the spear repository am I on? Am I synced to a specific tag, or am I synced to the head of the main branch?

Branch: main

What am I attempting to do, what do I expect to happen, and what actually happened?

I'm attempting to create my own scene in the simulation and spawn objects in the scene and create a scene in the environment.

Can you please suggest me how do I go about this? I've searched through the contents of the documentation. But it is not clear.

Hi. We don't currently have good support for spawning custom objects. The spawning behavior in SPEAR is painfully hard-coded right now. But we'll be improving things significantly in our next release, which we will ship in a few weeks. Thanks for trying out SPEAR, and please stay tuned!

Hello @mikeroberts3000. Thanks for your prompt reply. Looking forward to the further releases of spear.

Currently I've seen few scenes, in the spear release. debug_0000, debug1_0000, apartment_0000 and warehouse_0000. I extracted the SpearSim-Linux.pak and warehouse_0000-v0.4.0-Linux.pak through the ./UnrealPak /source/dir/ -Extract /destination/dir/ command to make changes to the warehouse scene for the way we desired. I was able to open the unreal levels of debug_0000, debug1_0000, apartment_0000 but not for warehouse_0000 level. There were no .umap or .uexp extension files in the extracted version of warehouse_0000-v0.4.0-Linux.pak.

Very grateful if we can receive your input on this. Thanks and cheers.

We don't officially support using the UnrealPak tool in the way you're describing. But in our next release, we will have a general-purpose Python interface that can be used to modify the scenes at runtime.
