MaxScript, Quick Boolean script.

Fwap

Yo,

I'm trying to write a script that booleans two meshes together, preferably subtraction, and then converts the mesh to editable poly.
I got as far as to do the boolean operation and it converts to a poly, all spicko and nice, trouble is if i try run the script again on the same mesh, but with a different boolean mesh, the results triangulate.

I think it might be because i'm using booleans instead of probooleans, but i've looked into that but i don't know how to code those.

Here's what i have, mostly kit bashed from stuff i've found online and the reference docs. 


(forgive me i don't know how to do the code thingo)

if selection.count < 2

then messageBox ("Please select at least 2 Objects. Thanks.")

else (

objectCount = 1

objectAll = selection.count

 

while objectCount < objectAll do (

objectCount = objectCount + 1

boolObj.createBooleanObject selection[2]

boolObj.setBoolOp selection[2] 4

boolObj.SetOperandB selection[2] selection[1] 4 3

)

GeomButNotPoly = $

ConvertTo GeomButNotPoly Editable_Poly

)

PolyHertz

select the meshs then run this (first mesh selected is the one that'll be kept):

allSel = selection as array
if allSel.count >= 2 then (
	keepMesh = allSel[1]
	delMeshs = deleteItem allSel 1 
	ProBoolean.createBooleanObjects keepMesh delMeshs 2 0 0
	ConvertTo keepMesh Editable_Poly
)
else (messageBox ("Please select at least 2 Objects. Thanks."))

Alternatively, if you decide that instead of converting to an Editable_Poly each time you want to keep the main mesh as a ProBoolean object, and just add more boolean meshs as you go (without relying on the UI), use this:

allSel = selection as array
if allSel.count >= 2 then (
	keepMesh = allSel[1]
	delMeshs = deleteItem allSel 1 
	if (classOf keepMesh != ProBoolean) then (ProBoolean.createBooleanObjects keepMesh delMeshs 2 0 0)
	else (for node in delMeshs do ProBoolean.SetOperandB keepMesh node 0 0)
)
else (messageBox ("Please select at least 2 Objects. Thanks."))
