Hey all,<\/p>\n

I’ve put together the following short MaxScript to allow you to assign a random material ID to a selection in 3dsMax. \u00a0I’ll update it into a full tool if I get enough comments asking for it.<\/p>\n

Here’s how you use it<\/strong><\/h2>\n
    \n
  1. Select an edit_poly object,<\/li>\n
  2. Select the polygons you’d like to assign random IDs to,<\/li>\n
  3. Copy this script into a maxscript file (MaxScript > New Script…),<\/li>\n
  4. Hit Ctrl + E to run the script.<\/li>\n<\/ol>\n
    numberOfSubMaterials = 3  -- Set the number of sub-materials here!!\r\noriginalSelection = polyop.getFaceSelection $\r\ncountOriginalSelection = originalSelection.count\r\n\r\nfor i=1 to numberOfSubMaterials do\r\n(\r\n\tantiArray = #{1..countOriginalSelection}\r\n\tfor i=1 to antiArray.count do antiArray[i] = (random 0 1) >= 1\r\n\tmergedArray = originalSelection * antiArray\r\n\tpolyop.setFaceMatID $ mergedArray (random 1 numberOfSubMaterials)\r\n)<\/pre>\n
    Also, here’s another that assigns a random material\/materialID to a collection of objects.<\/p>\n
    \r\nundo on\r\n(\r\n\tnewMaterial = multiMaterial numsubs:32\r\n\tfor i = 1 to 32 do\r\n\t\tnewMaterial[i].diffuse = random (color 0 0 0) (color 255 255 255)\r\n\t$.material = newMaterial\r\n\r\n\tfor obj in $ do obj.material = newMaterial[random 1 32]\r\n)\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
