I have a problem with the Boolean operation ‘difference’. Two closed objects are given. In the first one there is a cylinder with 146 vertices (24 segments, in 6 levels). It is the base object. In the difference object there are 58 UVspheres with each having 18 segments and 18 rings each. So we have a lot of vertices here (17864). The second object is penetrating the first one (each UVsphere penetrates the cylinder in the same way).
I used Blender 2.34 and I received a result object in about one minute. Unfortunatelly it has some errors, but with 30 minutes of work I could fix them by hand.
Now I am using Blender 2.40. Here the process takes a lot of time - nearly one hour - and finally no result appears. With a testing object having 4 UVspheres as difference for a cube I get a result but it takes some minutes.
Does anybody know if there was a major change in release 2.40 in this function? Is this a known problem or do I habe to do it in an other way. Please give no solutions like “there are to many vertices” - the older version could do it.
