I want to be able to use the VRay for Rhino methods in a VBScript code, but when I try something on the lines of

```
Dim vRay: vRay = Rhino.GetPlugInObject("V-Ray for Matrix")
Dim name: name = vRay.GetMaterialNameFromVismat(vismat_file_path)

```

I get

```
Object does not support this property or method

```

Am I understanding something wrong?

Hi Bhupati,

In VBScript you cannot assign an Object to a variable of type **Variant**. You have to use `Set` like below:

```auto
Option Explicit 

Call Main()
Sub Main()

Dim VRay, name, f

    Set VRay = Rhino.GetPlugInObject("V-Ray For Rhino")
   
    f = "D:\Software\VRay\Materials\360Materials\aqua\aqua.vismat"
    name = VRay.GetMaterialNameFromVismat(f, 1)
    If len(name) = 0 Then 
        Rhino.Print "Error" 
    Else
        Rhino.Print "MaterialName: " & name
    End If
   
End Sub

```

## Does that help ?

@clement Nope! I’m still getting the `Object required for Rhino.GetPlugInObject` error. Did it work for you?

Here are a view tips to try

1. Is V-Ray for Rhino/Matrix loaded and able to generate renders?

2. If you have matrix installed, I always prefer to use the GUID vs Plugin name to find the plug in object.

3. Is vismat\_file\_path a string?

GetPlugInObject("{E8CFE179-B60C-411A-8416-62A893334519}")

I was able to get the below code to work:

```
Option Explicit

Call Main()
Sub Main()

	Dim VRay
	Set VRay = Rhino.GetPluginObject("{E8CFE179-B60C-411A-8416-62A893334519}")

	' The bool at the end is "show error"
	Dim name: name = vRay.GetMaterialNameFromVismat("c:\test.vrmat", False)

	Rhino.Print "Material Name" & name

End Sub
```

</div>

@krsnadas it`s always good to use the plugin ID as “V-Ray for Matrix” is not the same as “V-Ray For Rhino”, but both have the same plugin ID. You might also test using IsObject to prevent the error, when VRay is not loaded eg:

```auto
If Not IsObject(VRay) Then 
    Rhino.Print "Error"
    Exit Sub
End If

```

## btw. as Matt has mentioned in his code, the bool value, i would always recommend to set it to True. If the Error is not shown and a material is not found (eg. when the material path is invalid), the `VRay.GetMaterialNameFromVismat` returns an empty string.

Thanks, @matt_newberg and @clement. I am able to call the vRay object now, but really intrigued why this happens:

`GetMaterialNameFromVismat(...)` returns this

/WhiteReflective-7a1ea260-ded9-4cec-9216-f070a11d4720

BUT, `Rhino.MaterialName(...)` returns this

/WhiteReflective-7a1ea260-ded9-4cec-9216-f070a11d4740 (last two digits are different each time I call!)

which essentially means this is the name stored in the table and as a result returns null when I search for Rhino.MaterialIndex.

Note: I loaded the material using `Rhino.Command("-visLoadVismat " + vismat_file_path)`

Sorry, I reckon what’s going on. Material being loaded multiple times and I guess that changes the URL each time.

@matt_newberg Also, I tried calling ApplyVRayMaterialToObjects, but I get an error ‘Object does not support this method’. Any idea what’s going wrong?

```
f = "C:\WhiteReflective.vismat"
Call Rhino.Command("-visLoadVismat " + f)
Dim strObject: strObject = Rhino.GetObject("select")
Dim vRay, mat_name, i, name, mat_index, materials, str_name, thisStr, obj_index
Set vRay = Rhino.GetPluginObject("{E8CFE179-B60C-411A-8416-62A893334519}")
mat_name = vRay.GetMaterialNameFromVismat(f, False)
vRay.GetSceneMaterialNamesScript materials
str_name = "WhiteReflective"
For i = 0 to UBound(materials)
    thisStr = materials(i)
    If InStr(thisStr, str_name) <> 0 Then
        Exit For
    End If
Next
vRay.ApplyVRayMaterialToObjects thisStr, 1, strObjects
```

There is a typo in your method name, it should be `ApplyVRayMaterialToObjects`

Haha, good catch @clement. I typed it in here instead of pasting. But I’m sure I have it typed right in my script, so the error still stands!

The error you get should also print out a line number where to look for the error. I do not think that above quoted method of your edited code snippet exists. It should be `GetSceneMaterialNames`

Actually, I’m not sure why two separate functions exist, but both `GetSceneMaterialNames` and `GetSceneMaterialNamesScript` work just fine with the same result!

And, @matt_newberg approves! [A bit more about V-Ray scripting](http://discourse.mcneel.com/t/a-bit-more-about-v-ray-scripting/20663)

@matt_newberg mentioned this somewhere. There is a help file for VRay scripting called VRayForRhinoExports.h which, for me, is in C:\ProgramData\VRAYMATRIX2\VfMatrix64\

Yes, and in this reference i do not have `GetSceneMaterialNamesScript`, that is why i mentioned it.

Version differences maybe? I’m not sure. But I just checked again and it does have it in mine.

Ok. Back to your code snippet above, what is the variable **f** pointing to ? It seems incomplete to me.

Sorry, okay corrected it above, but again got it right in my script. f is pointing to the path of the material file.

GetSceneMaterialNamesScript stores the array of strings slightly differently. I believe I wrote it to get around an issue with PythonScript/Rhinoscript.
