Re: Boolean engine did not cope. Result becomes first polygon mesh input

Eric..

I don't understand what is so *horrible* about XSI's boolean system. 3DS Max 
has horrble booleans (its better nowadays.. but it was (and still can be) 
alittle flaky at best).

Im going to hazzard a guess; you are expecting (two curved mesh for example) 
to nicely subdivide once the boolean operation is complete? Is that it? If 
not.. please do tell.. I am curious to know.. in any event, keep in mind 
that after a boolean operation, it is probably a good idea to clean up the 
mesh by adding/cleaning up edges to quadrify your mesh before expecting 
boolean operations to work for subdivided meshes. This is not the fault of 
xsi.. as I have done alot of booleans and the results in their own right is 
correct. But depending on how meshes intersect eachother will determine if 
you mesh has the need to be modified for polysubdivisions. People may be 
expecting a magic solution to things like booleans, but in the end, it is 
still up to the talent of the modeller to ensure that the meshes are well 
constructed (before/ and/ or after boolean modifications). By cleaning up 
your mesh for hard edging/beveling/etc.. is most likely going to be 
required.

But I am curious as to why xsi's booleans are so *horrible*. From where I 
stand.. it is actually quite solid.

Cheers,

NRG
