Max中UVW的修复脚本

今天发现有时候Max的UVW坐标会出现浮点数越限的情况，就变成了非法的浮点数,显示为 1.#QNAN 。从下面这段脚本的判断也可以明白是什么状况，即坐标既不大于等零也不小于等于零.....。出现此状况后在点级别就完全无法操作，可以用下面这段脚本解决，也可以将模型导成某种格式再导回来,同样可以达到效果。

Fn RepairUVW targetMesh =
(
    sourceClass = ClassOf targetMesh.Baseobject
    ConvertToMesh targetMesh
    for  fi = 1 to GetNumFaces targetMesh.mesh do
    (
        ft = GetTVFace targetMesh.mesh fi
 
        for ni = 1 to 3 do
        (
            tempUvw = getTVert  targetMesh.mesh  ft[ni]
            for ui = 1 to 3 do
            (
                if (not tempUvw[ui] >= 0) and (not tempUvw[ui] <= 0) do tempUvw[ui] = 1
            )
            SetTVert  targetMesh.mesh  ft[ni] tempUvw
        )
    )
    Update targetMesh
    if sourceClass == Editable_Poly do ConvertTo targetMesh Editable_Poly
    AddModifier targetMesh (Unwrap_UVW())
)
 
for tempObj in Selection  as array do RepairUVW tempObj
