Hello all,
I am wanting to insert my own 3D renderings of objects in my house in my UE project. What free photogrammetry softwares are compatible with Unreal Engine 4?
I was hoping to download MicMac, Colmap or Meshroom.
Thank you for your help!!

UE4 can import .obj and .fbx static mesh formats, so for Meshroom that works out of the box because it works with .obj internally. Although you probably should retopo the object or at least decimate before importing it depending on the poly count produced by the tool and of course your memory budget for the project. If you want to stay in free/opensource zone you can use something like Instant Meshes or Blender to do that.
MicMac and Colmap produce Stanford .ply files so it can not go directly into UE4 but reducing the number of triangles and vertices is recommended in any case and both Instant Meshes and Blender can import .ply files, so the workflow is the same as with .obj.
That said, there would probably be more work needed to get it to look realistic regarding textures and materials. Photogrammetry usually captures a lot of ambient lighting and bakes it into textures which makes things look unnatural when put in different lighting environment in the engine. Also glossiness is lost in the process too. So those things probably need to be reconstructed manually.
Good luck.
Hey Livada,
Thanks for answering. So best is to use Blender to then import into Unreal? I was just wondering, does Blender do the photogrammetry automatically? (Sorry if this questions sounds silly, I am very new). For exemple, if I take 300 photos or so of an object, can I process them into Blender to then create a 3D object?
Kind regards,
M
