I have an terrain object that I want to divide into chunks of the same size. I already created a grid (black lines) with that I could slice the mesh. I want every chunk to be a separate object. Any ideas?

    $\begingroup$ Hi Allen, although i used Blender once or twice...i don't get it. after i made knife project on my displaced plane with my plane above, i got this: [1]: i.sstatic.net/FjLTG.png is this already wrong? if i do edge split on that and separate by loose parts, i got way to many parts: [1]: i.sstatic.net/sNEOR.jpg so maybe a more detailed answer would help...at least me...a knife project beginner $\endgroup$

    $\begingroup$ Thank you for your answer. Knife project works fine, but as Chris mentioned, edge split and separate by loose parts wont create squared chunks. A more detailed answer would be great. $\endgroup$

I tried that workflow and it worked for me. This is what I did:

  1. Create the grid deleting all the faces: enter image description here

  2. Create a simple plane and rotate it for some variation: enter image description here

  3. Apply knife project with the grid on the plane: enter image description here

  4. Add Edge Split modifier:

enter image description here

  1. Set angle to 0 degrees to apply to all edges:

  1. Apply modifier and enter edit mode to check if all chunks are detached: enter image description here

  2. Apply Separate by loose parts:

enter image description here

  1. Check that all expected objects have been created:

Hope this helps.

    $\begingroup$ yeah, with your super simple setup where the plane isn't subdivided at all...that's easy. Now subdivide your plane 30 times and do it again...and it won't work. Cutting a non subdivided plane might be good for demo purposes...but in reality in CG a plane has subdivisions...And a terrain object i would guess has subdivision, else you won't get height in it. $\endgroup$

  • $\begingroup$ How would I get split objects in the case where I have topology on these chunks? The edge split won't work here for me. $\endgroup$
