So try this. Open a blank scene. Make a teapot. With it selected, run this code:
objs = #()
for i in selection do (append objs i)
for i in objs do
(
m = unwrap_UVW()
addModifier i m
m.setMapChannel 2
m.flattenMap 45 #([1,0,0], [-1,0,0], [0,1,0], [0,-1,0], [0,0,1], [0,0,-1]) 0.02 true 0 true true
)
Now open the UVunwrap editor, and notice that instead of flattening it, it seems to have just done a planar projection from above.
Now run the code a second time, now open the UVunwrap editor, it’s now done what I would expect, it has flattened the mapping.
Now delete both UVUnwrap modifiers from the teapot, run the code a third time, it produces the correct results.
Anyone know why it produces the incorrect results the first time? Thanks for any insight.

you need to add
[left]
[/left]
[left]
setCommandPanelTaskMode mode:#modify
[/left]
[left]
as the first line in your code
[/left]
Still not works.
When you create Teapot by the code then works.
But when you try on multiple nodes U need to be for sure in modify panel and select one by one every node and apply the operation.
Try this
(
if getCommandPanelTaskMode() != #modify do setCommandPanelTaskMode #modify
objs = getCurrentSelection()
if objs.count > 0 do for o in objs do
(
select o
addModifier o (unwrap_UVW())
o.Unwrap_UVW.setPreventFlattening off
o.Unwrap_UVW.setMapChannel 2
o.Unwrap_UVW.mappingReset()
o.Unwrap_UVW.flattenMap 45 #([1,0,0], [-1,0,0], [0,1,0], [0,-1,0], [0,0,1], [0,0,-1]) 0.02 on 0 on on
deselect o
)
)
I looked at your code, then checked with mine that I use, the difference is that I select all the uv faces before I flatten.
--select all uv faces
$.modifiers[#unwrap_uvw].selectFaces #{1..z2}
--unwrap with parameters
$.modifiers[#unwrap_uvw].flattenMap 45.0 #([1,0,0], [-1,0,0], [0,1,0], [0,-1,0], [0,0,1], [0,0,-1]) 0.01 true 0 true false
Thanks everyone, will try all the code and see which one works best.
