Graphics

Hi, I have a scene in which I would like a default silhouette image to be visible only if a datalinq image returns empty.

So, I have two quads, one default image, and one with a datalinq material which points to a path/filename, and if Xpression can find the corresponding image file, it shows, and if not it's left blank. So far, so good. But I just can't figure out how to build a visual logic to show the default image only when the datalinq image is empty.

Any suggestions?

Below is a simplified version of what I'm using to accomplish this...

'This is a script to determine if file actually exists.

dim path as xpTextObject

Scene.GetObjectByName("PATH", path)

Dim fs As Object = CreateObject("Scripting.FileSystemObject")
Dim defaultImagePath As String = path.Text & "MISC\Default_Player.png"
Dim imagePath As String
imagePath = path.Text & triCode.Text & "\" & lname.Text & "_" & fname.Text & ".png"
If Not(fs.FileExists(imagePath)) And fs.FileExists(defaultImagePath) Then
engine.DebugMessage("Headshot " & imagePath & " doesn't exist. Setting to default player photo instead.", 1)
imagePath = defaultImagePath
End If

'set Volatile Texture

dim HS as xpBaseObject

Scene.GetObjectByName("Headshot", HS)
HS.SetVolatileTextureFile(0, imagePath)

Hi, thanks for this!
So, do you run the script on the whole scene, or on the image (quad), or something else?

In this case, the script is located on the default scene director.
