I made a Mesh combination tool. Have a look! (gitlab.com)

Exactly what the title says. It's under MIT lisence and currently being approved by the moderators of the AssetLib. The project is currently very simple and contributions are very welcome! image of the tool window

That looks great! I've been wanting a way to do this.

Does it have that functionality of a regular Mesh3D in the GUI where you can automatically create a collision shape from the (combined) mesh?

[–] Smorty@lemmy.blahaj.zone 3 points 5 months ago (1 children)

No but that is a great idea to implement! There are two ways I could go about this. Maybe you could give me some feedback on this?

  • Option 1: Select a single MeshInstance3D Node > in the Mesh menu, select the Combine similar into MultiMeshInstance3D and that autoamtically combines the MeshInstance3Ds in the same parent Node
  • Option 2: Select all MeshInstance3Ds you want to combine and then select that same option under the Mesh menu

Which one do you prefer?

[–] eezeebee@lemmy.ca 3 points 5 months ago

Ooh, I think I like the sound of Option 2 the most. I find myself selecting multiple meshes already, but without your tool, I end up doing this repeatedly as I make adjustments. Sounds like I could just select the desired meshes once and combine which would be amazing.

Thanks!

Oh wait i think i actually misunderstood your original question. I thought you wanted to see the combination option in that Mesh Submenu, but you seem to have actually referred to the ability of adding collision to a combined MultiMeshInstance, do i understand that correctly now?

I actually already implemented the ability to carry over collisions from the original objects to the combined objects as an optional setting. Explanation video of the tool here. But having the ability to add collision to a MultiMeshInstance without having any prior configuration is also a very interesting idea. This might be a bit out of my current knowledge of the engine, but i can try!

Sorry for the delayed response! Yes, that is exactly it. I want to skip creating Collision for each one of the primitive shape MeshInstance3Ds. It would be a bonus if I can choose to consolidate the meshes and collision shapes:

  1. Option to consolidate meshes, or not
  2. Option to create multiple collision for selected meshes, OR create consolidated collision for these meshes

Thanks for the response. I am going to try playing with OptiScene :)
