| Jul 13, 2019 at 8:15 | comment | added | Jan Kadeřábek | @batFINGER Thanks, but one of my requirements is to explode the mesh using it's existing topology, not by creating extra cuts - this would create a lot of unnecessary extra vertices. It should basically select an area of 25k vertices, copy it into new object and continue with a next part. | |

| Jul 12, 2019 at 18:24 | comment | added | Jan Kadeřábek | @lemon It must be automated, no hand cutting, even switching into Edit Mode is very slow in Blender in case of such large mesh. The part in the uploaded .blend is just a very small portion of the overall mesh (which is 40km consisting of a road + surroundings covered by vegetation). | |
| Jul 12, 2019 at 18:10 | comment | added | lemon | I've joined it again (if, see previous comment). I think you should use a dichotomy to separate the parts. Cut in half, cut the half in half, etc. The more the mesh is divided the more it is fast (doing it from Blender GUI). | |
| Jul 12, 2019 at 18:07 | comment | added | lemon | the file you've uploaded is already cut, right? so join it again will make the base mesh? | |
| Jul 12, 2019 at 17:57 | comment | added | Jan Kadeřábek | @HenrikD Split into grid? I am not sure I understand you. It must produce pieces of around 25k vertices. I would like to duplicate it into chunks by Python, but I struggled especially with preventing UVs, Vertex Colors and Materials, unfortunately my skills are quite limited. Separate by Loose Parts can't be used as it must work with larger continuous meshes (like the ground) but at the same time it shouldn't produce too many small chunks (in case of individual trees or grass clusters). | |
