Legacy:Transform Permanently
This page should give a simple explanation of the Transform Permananetly command... work in progress, feel free to add.
shunted from the beginner faq:
When you're trying to rotate a brush and it doesn't want to, it just changes shape as you try to rotate it, this is what to do.
- Brush Context Menu -> Transform -> Transform Permanently
Also use Transform Permanently on brushes which you've scaled, etc.
Alignment
Align the textures *after* you used transform permanently, since it will reset your brush completely, including the alignments of the textures. Try to use it while you're finishing your map, and only if you're positive you won't change the brush anymore.
Deep into Transform Permanently
When using Unreal Engine 1.0 and 2.0 versions, brushes vertex values are not updated if you rotate or scale up/down it. It is using Rotation,MainScale,PostScale and TempScale to do so. See sample brush here taken from AS-Mazon(Unreal Tournament) map:
<uscript>Begin Actor Class=Brush Name=Brush6
CsgOper=CSG_Add
MainScale=(SheerAxis=SHEER_ZX)
PostScale=(Scale=(X=50.000000,Y=73.000000),SheerAxis=SHEER_ZX)
PolyFlags=67109132
Level=LevelInfo'MyLevel.LevelInfo0'
Tag=Brush
Region=(Zone=LevelInfo'MyLevel.LevelInfo0',iLeaf=-1)
Location=(X=4352.000000,Y=-4000.000000,Z=-16.000000)
Rotation=(Yaw=-16384)
Begin Brush Name=Model7
Begin PolyList
Begin Polygon Texture=Swater4a Flags=67109132 Link=0
Origin -00064.000000,-00064.000000,+00000.000000

Vertex -00064.000000,+00064.000000,+00000.000000
End Polygon
End PolyList
End Brush
Brush=Model'MyLevel.Model7'
PrePivot=(X=64.000000,Y=64.000000)
Name=Brush6
End Actor</uscript> When using "Transform Permanently",the editor updates vertex,prepivot,origin and normal values so that Rotation and scale values are not set.
Here you can see the "transformed" brush: <uscript> Begin Actor Class=Brush Name=Brush6
CsgOper=CSG_Add
MainScale=(SheerAxis=SHEER_ZX)
MainScale=(SheerAxis=SHEER_ZX)
PolyFlags=67109132
Level=LevelInfo'MyLevel.LevelInfo0'
Tag=Brush
Region=(Zone=LevelInfo'MyLevel.LevelInfo0',iLeaf=-1)
Location=(X=4352.0,Y=-4000.0,Z=-16.0)
Begin Brush Name=Model7
Begin PolyList
Begin Polygon Texture=Swater4a Flags=67109132 Link=0
Origin -3200.0,4672.0,0.0

Vertex -3200.0,4672.0,0.0
Vertex -3200.0,-4672.0,0.0
Vertex 3200.0,-4672.0,0.0
Vertex 3200.0,4672.0,0.0
End Polygon
End PolyList
End Brush
Brush=Model'MyLevel.Model7'
PrePivot=(X=3200.0,Y=-4672.0,Z=0.0)
Name=Brush6
End Actor</uscript>
Algorithm <uscript> For brush:
Set Rotation=0 Set MainScale=0 Set PostScale=0
For Origin and each vertices:
Do *= MainScale Then MakeRotate(Pitch,Yaw,Roll) Finally: *= PostScale
For Normal:
Do MakeRotate(Pitch,Yaw,Roll)
</uscript>
