Graphics

Hi,

I'm working on a project with many flags with differente sizes, I first wanted to use Dynamic Material : E:\MyProject\FLAGS\@Txt_Member1@_flag.png

Where Txt_Member1 is the 2 letters of the country ex : JP__flag.png UK_flag.png CH_flag.png and so on Txt_Member1 is Datalinqed to an Excel file.

But because Dynamic Material is only changing the image it doesn't affect the Quad itself so all the flags have the same size.

To make it work I need to apply the flags from the Material Manager and not from a Folder.

Any idea on how to make it Dynamic from the Material Manager, maybe a piece of Sript ?

Regards.

First question have you tried this setting

Second part, yes you can use this script to apply a material 

dim box as xpBaseObject

dim mat as xpMaterial

 

Scene.GetObjectByName("Quad1", box)

 

if text = "D" then

engine.GetMaterialByName("blue", mat)

box.SetMaterial(0, mat)

end if

 

if text = "R" then

engine.GetMaterialByName("red", mat)

box.SetMaterial(0, mat)

end if

 

if text = "I" then

engine.GetMaterialByName("white", mat)

box.SetMaterial(0, mat)

end if

Hi Simon,

I tried your Quad options settings but unfortunately it's not working.

I'm gona try both options VL and Script.

Karim,

Sometimes coding is not the solution.

I would set a standard image size and batch it in photoshop so that those that don't fit the ration has a transparency in the dead area.

Or, batch all images to have a 1 or 2 transparent pixel edge. Have the quad set to "best fit" and "maintain aspect ratio". In texture coords, Misc. - Mode set to border or clamp.

This way the texturing process does the heavy lifting.

I must say I agree with Azathoth here. While finding a script or VL solution is nice from a nerdy tech standpoint, operationally, assuming these are flags as you say and there isn't a specific reason why sizing needs to happen in Xpression, sometimes simplicity is the best solution, and resizing these in an editor like photoshop is probably most efficient and reliable solution. I have had to do this for large tournaments regularly, and yes it takes some time to conform all countries' flags, crest etc, but it's a done once solution with 100% predictable output in Xpression.

Are the flag sizes close enough in resolution that you can just select the Auto Size "On Material Assign Only" option in the Quad?

You can also call on Project Materials in a dynamic material path by referencing a Material by name in the string.
