[3ds Max] script vertex compare

naskeleton

Hi guys, I have made a script that is supposed to find the difference between the position of every vertex in a first mesh and a second mesh.

The goal is to automatically select for morpher the vertex that require vertex color to white and with a Ctrl+i the black vertex color.

Currently the script work with simple mesh like cube, but when I try with more complex mesh, it didn't work.
maybe it's because array are limited ?

Thx for your help.

1. sM1 = #()
   
2. sM2 = #()
3. cV1 = #()
4. cV2 = #()
5. aDV = #()
6. pCb1 = #()
7. pCb2 = #()
8. sPO1 = #()
9. sPO2 = #()
10. 
    
11. aDV as array
12. 
    
13. rollout pick_box_test "Pick Meshes"
14. (
15. pickbutton chooseit1 "Pick Mesh 1" width:140

36. if pCb1 and pCB2 do 
37. if sM1.verts.count == sM1.verts.count do
38. for i=1 to sM1.verts.count do
39. (
40. sM1.selectedVerts = #{i}
41. cV1 = sM1.verts[i].pos
42. cV2 = sM2.verts[i].pos
43. if cV1 != cV2 do appendIfUnique aDV i
44. )
45. sM1.pos = sPO1
46. sM2.pos = sPO2
47. sM1.selectedVerts = aDV
48. )
49. )
50. createDialog pick_box_test

The problem is that you compare float values directly. Use this instead:

if distance cV1 cV2 > 0.001 do appendIfUnique aDV i

And read this: Comparing float values, by Swordslayer.
And make all variables from the first 11 rows local.

Thank you very much guy, I love you
