A question about MAXScript

[panghsheng]

I want to implement a functionality where, in the currently active SME view, I search for all VRayMtl nodes. If found, I check if the node connected to the diffuseMap port is a VRayBitmap. If it is, I modify coords.blur to 0.01. If not, I traverse all output ports of the material until I find a VRayBitmap and set its coords.blur to 0.1. Below is my code, but I don't know why it's throwing errors.

function setVRayBitmap m =
(
    diffuseMap = m.diffuseMap
    if isKindOf diffuseMap VRayBitmap do
    (
        diffuseMap.coords.blur = 0.01
    )
    if not isKindOf diffuseMap VRayBitmap do
    (
        for i = 1 to m.numOutputs() do
        (
            outputMap = m.getOutputMap i
            if isKindOf outputMap VRayBitmap do
            (
                outputMap.coords.blur = 0.01
               return
            )
        )
    ) 
)

function SMEGetMatsInView = 
(    
    viewNode = sme.GetView (sme.activeView)
    for n = 1 to trackViewNodes[#sme][(sme.activeView)].numSubs do 
    (
        m = trackViewNodes[#sme][(sme.activeView)][n].reference
        if classOf m == VRayMtl do 
        (
            setVRayBitmap m
        )
    )
)

SMEGetMatsInView()

What is this, a game? Do we have to guess the errors first and then tell you how to fix them?

Thank you for your reply.

Thank you for your reply. This is not a game. I want to batch change the parameters of VRayBitmap, as shown in the figure below. In the currently active view window of SME, I want to batch change the value of coords.blur of VRayBitmap. However, the value depends on which port it is in VrayMtl. If it is under diffuseMap, the value of coords.blur of VRayBitmap is 0.1. If it is under reflectionMap, the value of coords.blur of VRayBitmap is 0.01. Or if it is under BumpMap, the value is 0.03.

post the error messages you get... screenshots of the message box and the log from the listener

[panghsheng]

Okay, thanks again for your response。：）

[denisT.MaxDoctor]

at line 16 of your code should be

return ()

this is why you should post "errors"... 

[panghsheng]

This is the result after adding parentheses. I suspect there might be an issue with the logic of the entire code.

[denisT.MaxDoctor]

the error log tells you everything... "in line 10 the material doesn't have a method or property #numOutputs"

so see the documentation on how to get the correct number of VRay material outputs

Step by step, we'll first correct all the syntax errors, then move on to the logical ones... and then, possibly, to the stylistic ones.
