For something so simple there are surprisingly little Google results, likely because I'm a noob and everyone already knows how to do this.
I have imported a Collada DAE 1.4 file, that I made in another 3D modeling tool, into Blender. In Blender, the model is shown very large, and it isn't centered at the origin. I want to start by moving the model to the centre of Blender's grid.
However, the model file contains multiple objects, and I'd like to keep it that way. I knew to centre an object, you can go Object>Geometry to Origin. The problem is that every selected object gets moved to the centre of the grid with total disregard for every other object around it.
I am aware there is some z-fighting going on, but I will fix that after my model is centered and scaled. Here's the model as it should appear. The 3D cursor is way off in the background behind the skydome, in its original position at the centre of Blender's grid, and I want the centre of this model to be there.
Yes, everything is centered, but no longer is the model laid out the same way as before. Instead, every single object is now at the centre, instead of there being a sort of "bounding box" put around everything and centering the bounding box instead of each individual object. The wings, which were in its own object, are at the centre, and the tail, which was its own object as well, is now also in the centre - rather than remaining attached and being treated as if one object.
I could just combine every object using Ctrl+J. But I'd like to centre everything while keeping the objects separate.
