Note
CSDK 12 now ships with a Hero Image Template to skip decompilation. Use Duplicate Addon on a addon template in the CFG Tool to make an editable version of the addon.

Requirements
Source 2 supports making .vtex_c files out of various image filetypes.
There are multiple ways to make and compile a UI texture:
VData
Since a .vdata file automatically recompiles any referenced panorama images when that .vdata file is recompiled, you can use this template to compile your images.
Create a new file named image_compiler.vdata in the panorama or scripts folder of your addon, copy the template below and paste it into the file. Modify the image_list section to reference your own images ({images} is the panorama/images folder).
<!-- kv3 encoding:text:version{e21c7f3c-8a33-41c5-9977-a76d3a32aa0d} format:generic:version{7412167c-06e9-4698-aff2-e63eb59037e7} -->
{
generic_data_type = "panorama_image_list"
image_list =
[
panorama:"file://{images}/heroes/archer.psd",
panorama:"file://{images}/heroes/archer_card.psd",
panorama:"file://{images}/heroes/archer_mm.psd",
panorama:"file://{images}/heroes/archer_sm.psd",
panorama:"file://{images}/heroes/archer_vertical.psd",
]
}
Then, find this file in the
Asset Browser, right click on it and select “Recompile > Full”.

Making a VPDI file
Warning
If you are using CS2 to compile UI textures, be aware that compilation of
.vpdiresources doesn’t work. Use the above.vdatamethod instead.
VPDI (Valve Panorama Dynamic Images) is a file that compiles all UI textures defined in it. Here’s how it looks like:
"DynamicImages"
{
//-------------------------------------------------------------------------
// Changing absolutely any file referenced below
// will cause a rebuild if it is
// a directly referenced image in content.
//-------------------------------------------------------------------------
"Explicit Files"
{
"{images}/heroes/rimdle.png" ""
"{images}/heroes/rimdle_mm.png" ""
"{images}/heroes/rimdle_sm.png" ""
"{images}/heroes/rimdle_vertical.png" ""
"{images}/heroes/rimdle_card.png" ""
}
}
First, make a .vpdi file in the panorama folder of your addon (you can copy the example above). Then, define all of your images in the “Explicit Files” section ({images} is the panorama/images folder).
With your
CSDK 12 tools open, find your .vpdi file in the
Asset Browser, right click on it and select “Recompile > Full”. Compilation of this file will recompile all referenced images to .vtex_c.
