Rotate UVW +90 & -90

[Anonymous]

I'm trying to rotate a selected face via maxscript +90 degrees and -90 degrees in the Unwrap UVW Modifier.

I can mirror using...

$.modifiers.unwrap.mirrorv ()
$.modifiers.unwrap.mirrorh ()

But can't figure out how to rotate +90 and -90, listener doesn't pick up anything when I use the rotate buttons in the Unwrap dialogue.

From the maxscript help > Unwrap_UVW > Transform Selected:

<void><Unwrap_UVW>.rotateSelectedCenter <float>angle

Rotates the selected sub-objects at the specified angle using the selection center.

<void><Unwrap_UVW>.rotateSelected <float>angle <point3>axis

Moves the selected sub-objects at the specified offset about the specified axis.

The second one should be rotates, but that is copied direct from the Maxscript Help.

Thx Eric...that's the code i was trying to get to work, but in that format makes no sense to me.
I rotate in the Unwrap uvw with angle snap set to 90 degrees, and get this from the listener....

$.modifiers.unwrap2.RotateSelectedCenter 1.85878
$.modifiers.unwrap2.RotateSelectedCenter 0.933751
$.modifiers.unwrap2.RotateSelectedCenter 1.19555
$.modifiers.unwrap2.RotateSelectedCenter 1.14319
$.modifiers.unwrap2.RotateSelectedCenter 0.898845
$.modifiers.unwrap2.RotateSelectedCenter 1.40499
$.modifiers.unwrap2.RotateSelectedCenter 1.62316
$.modifiers.unwrap2.RotateSelectedCenter 1.16064
$.modifiers.unwrap2.RotateSelectedCenter 1.78024
$.modifiers.unwrap2.RotateSelectedCenter 1.46608
$.modifiers.unwrap2.RotateSelectedCenter 1.13446
$.modifiers.unwrap2.RotateSelectedCenter 1.37881
$.modifiers.unwrap2.RotateSelectedCenter 1.16064
$.modifiers.unwrap2.RotateSelectedCenter 1.19555

It seems to work, but I'm not sure how precise the 1.85878 is or what value to use for a precise 90 degrees.

thx

Ahh...s'ok got it fixed.... I typed "90 degrees in decimal" in google and got 1.57079633 🙂
That's much better 😉

thanks

2*PI radians = 360 degrees.
2*PI/4 = 1.57079633 = 90 degrees 😉

Or simply use the built in conversion tools:

Angle Conversion Methods
degToRad <number>
Returns the conversion of the number from degrees to radians. The result is always a float.

radToDeg <number>
Returns the conversion of the number from radians to degrees. The result is always a float.

A lot of the time when it comes to rotations the values will be a float radians rather than degrees.

$.modifiers.unwrap2.RotateSelectedCenter (degToRad 90.0)

Thx guys, that's comprehensively covered, and it works a treat.
