Experimenting I have noticed this. If I add the Remesh modifier with a large value of “Octree Depht” and apply the changes then “Limited Dissolve”, Blender hangs and I must kill the process.
How to reproduce the problem:
Add Remesh modifier to the default cube with “Octree Depht” value to 9 and apply the modifier. In edit mode select all and X > Limited Dissolve.
I have noticed that sometimes even Blender hangs just with “Octree Depht” large value without appling de modifier.
I have noticed that there is increased use of RAM, but not enough to exhaust the resources of my PC.
I know it is a large value of “Octree Depht” and there are many vertices. But I want to know if it is normal Blender hangs in these conditions.
Kubuntu Linux 64bits, 8GB Ram, nVidia GT 430 1GB, intel i7 3770
Please, I will be grateful if you do the test and tell me if you are having the same problem.
