从 3ds max 导入 fbx 后在 Maya 中删除属性

Question

感谢您的信息。 我就这样完成了mel。

select -all -hi;
string $allObj[] =`ls -sl -fl `;
for($i=0;$i<`size$allObj`;$i++)
    {
    select -r $allObj[$i];
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "mrFBXASC032displacementFBXASC032useFBXASC032globalFBXASC032settings"`;
if ($attrExists) {
    deleteAttr -at "mrFBXASC032displacementFBXASC032useFBXASC032globalFBXASC032settings" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "mrFBXASC032displacementFBXASC032viewFBXASC032dependent"`;
if ($attrExists) {
    deleteAttr -at "mrFBXASC032displacementFBXASC032viewFBXASC032dependent" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "mrFBXASC032displacementFBXASC032method"`;
if ($attrExists) {
    deleteAttr -at "mrFBXASC032displacementFBXASC032method" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "mrFBXASC032displacementFBXASC032smoothingFBXASC032on"`;
if ($attrExists) {
    deleteAttr -at "mrFBXASC032displacementFBXASC032smoothingFBXASC032on" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "mrFBXASC032displacementFBXASC032edgeFBXASC032length"`;
if ($attrExists) {
    deleteAttr -at "mrFBXASC032displacementFBXASC032edgeFBXASC032length" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "mrFBXASC032displacementFBXASC032maxFBXASC032displace"`;
if ($attrExists) {
    deleteAttr -at "mrFBXASC032displacementFBXASC032maxFBXASC032displace" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "mrFBXASC032displacementFBXASC032parametricFBXASC032subdivisionFBXASC032level"`;
if ($attrExists) {
    deleteAttr -at "mrFBXASC032displacementFBXASC032parametricFBXASC032subdivisionFBXASC032level" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "UDP3DSMAX"`;
if ($attrExists) {
    deleteAttr -at "UDP3DSMAX" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "MaxHandle"`;
if ($attrExists) {
    deleteAttr -at "MaxHandle" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "MaxVisibility"`;
if ($attrExists) {
    deleteAttr -at "MaxVisibility" $allObj[$i];
}
    int $attrExists = `attributeQuery -node $allObj[$i] -exists "currentUVSet"`;
if ($attrExists) {
    deleteAttr -at "currentUVSet" $allObj[$i];
}
}

显示另一个错误 Cannot delete static attribute 'currentUVSet' from node 'ObjectName'

复合属性的子属性不能删除吗？

或者删除属性'currentUVSet'不是必须的吗？

在我将 fbx 文件从 3dmax 导入到 Maya 之后。 这些对象有一些我不需要的属性。

"mrFBXASC032displacementFBXASC032useFBXASC032globalFBXASC032settings"
"mrFBXASC032displacementFBXASC032viewFBXASC032dependent"
"mrFBXASC032displacementFBXASC032method"
"mrFBXASC032displacementFBXASC032smoothingFBXASC032on"
"mrFBXASC032displacementFBXASC032edgeFBXASC032length"
"mrFBXASC032displacementFBXASC032maxFBXASC032displace"
"mrFBXASC032displacementFBXASC032parametricFBXASC032subdivisionFBXASC032level"
"UDP3DSMAX"
"MaxHandle"
"currentUVSet"

我尝试让 mel 删除它们。

string $allObj[] =`ls -sl -fl `;
for($i=0;$i<`size$allObj`;$i++)
    {
    select -r $allObj[$i];
    deleteAttr -at "mrFBXASC032displacementFBXASC032useFBXASC032globalFBXASC032settings";
    deleteAttr -at "mrFBXASC032displacementFBXASC032viewFBXASC032dependent";
    deleteAttr -at "mrFBXASC032displacementFBXASC032method";
    deleteAttr -at "mrFBXASC032displacementFBXASC032smoothingFBXASC032on";
    deleteAttr -at "mrFBXASC032displacementFBXASC032edgeFBXASC032length";
    deleteAttr -at "mrFBXASC032displacementFBXASC032maxFBXASC032displace";
    deleteAttr -at "mrFBXASC032displacementFBXASC032parametricFBXASC032subdivisionFBXASC032level";
    deleteAttr -at "UDP3DSMAX";
    deleteAttr -at "MaxHandle";
    deleteAttr -at "currentUVSet";
    }
}

如果我选择所有对象。 mel 将显示如下错误消息： does not have attribute 'UDP3DSMAX'

因为这些对象没有相同的节点。 如何正确删除所有属性？

如果你使用 catch 命令，你可以稍微降低复杂度：

string $attr[] = {"mrFBXASC032displacementFBXASC032useFBXASC032globalFBXASC032settings"
"mrFBXASC032displacementFBXASC032viewFBXASC032dependent"
"mrFBXASC032displacementFBXASC032method"
"mrFBXASC032displacementFBXASC032smoothingFBXASC032on"
"mrFBXASC032displacementFBXASC032edgeFBXASC032length"
"mrFBXASC032displacementFBXASC032maxFBXASC032displace"
"mrFBXASC032displacementFBXASC032parametricFBXASC032subdivisionFBXASC032level"
"UDP3DSMAX"
"MaxHandle"
"currentUVSet"};
string $sel[] = `ls -sl`;
for($i = 0; $i < size($sel); $i++)
{
    for( $k = 0; $k < size($attr); $k++)
    {
        catch(`deleteAttr -at $attr[$k] $sel[$i]`);
    }
}

这样你不必关心不存在的属性，当然你也不会看到其他可能发生的错误。

Answer 2

在调用deleteAttr之前，可以先检查属性是否存在：

int $attrExists = `attributeQuery -node yourObject -exists "yourAttr"`;
if ($attrExists) {
    deleteAttr -at "yourAttr" youObject;
}
