【问题描述】：

    -- this function selects polygons assigned to mat and assigns a matid of count
    -- mat is the mat to select the polys by and count is the mat id to assign to the polys

    function assignMatId mat count = (

        -- set the mat into meditMaterials in the second slot
        meditMaterials[2] = mat

        -- set the second slot to the active one
        medit.SetActiveMtlSlot 2 true

        -- select the polys assigned to mat
        objarr = for obj in objects where obj.material == meditMaterials[medit.getActiveMtlSlot()] collect o

        --assign selected polys a matid of count
             --.. still writing this code
    )

这是我正在尝试编写的函数。但是我目前停留在选择分配给垫子的多边形上。所以我的问题是：

我将如何给一个选定的材料（meditMaterials 中的 activeSlot）选择所有分配有该材料的多边形。材质可能分配给多个对象，因此它也需要选择到其他可编辑的多边形对象中。

有什么想法可以从哪里开始吗？

【解决方案1】：

function assignMatId mat count = (

    --collect all of our objects that are editable polys
    objs = for x in $* where classOf x == PolyMeshObject collect x

    -- collect all of our objects where the material is the same as the mat
    objarr = for obj in objs where obj.material ==  mat collect obj 

    -- go through and assign the correct mat id
    for obj in objarr do polyop.setFaceMatID obj #{1..obj.numfaces} count

)

我明白了。
