The ability to accurately swap between original screenshots released by Valve and the exact equivalent locations of each screenshot's given map allows for artists to find otherwise unnoticed details that they may miss when attempting to recreate an asset. As such, being able to find the exact positions and angles that official screenshots were taken at can be a worthwhile venture. The following are examples of official screenshots and their equivalent in-game locations.

Making your own Screenshot Recreations
Creating screenshot recreations requires a tool that can overlay separate windows with transparency, or a way to seamlessly change between windows. Glass2K for Windows is one such tool. It allows for the user to overlay screenshots onto their screen, thereby allowing said user to align their view to be the same as the original screenshot.
For the this task, this guide on opening Leak maps in Hammer++, and the VMF updater mappack may be useful. The updated maps will require less effort to fix up compared to the unmodified WC mappack maps.
A screenshot recreation requires a (close enough) version of the map shown available. Thus, the first step is to canvass the maps that seem to roughly match the one the shot was taken in until the closest one is found.
Fast compilations can introduce lighting artifacts, and aren't advised. This can make compilation time longer, but utilizing a cordon to remove everything that is invisible from the player's perspective alleviates this issue.
The map may already have a cordon - click “Edit Cordon” to interact with it, and “Enable Cordon” to activate it. In order to accurately determine what the player can see, drag-select (Hammer++ only) everything in the 3D viewport, and put the cordon around what is selected.
Enabling noclip is essential. Many screenshots use it, even if it doesn’t look like it. Further, noclip “snaps” to the ground to a certain degree, meaning it can even serve as a more precise way to “walk”.
Valve’s screenshots use both
fov 75 and
fov 90. Switching between the two is useful if the alignment doesn't seem to "just work".
Getting it Right
An important aspect of getting the alignment right is being able to increase movement precision. These commands are important for it:
For further degrees of freedom in movement,
binding a key to
+movedown. This allows vertical position adjustment with no effect on the view angle.
It’s easy to get myopically focused on comparing one area of the screenshot. Avoid this! One area can slip when another is being focused on. Try to get 3 or so different areas across the screenshot roughly there. Then, they can be more accurately perfected. Then, you can perfect one, perfect the other, fix any issues with the first, and repeat this for the third.
As adjustments become more precise, comparing the screenshots directly planning out movements can be beneficial. Simply unconsciously adjusting might reduce accuracy.
There is never perfect perfection, but if thee screenshot stops “moving” between the comparisons, that’s quite enough.
Before completion, type
getpos to save your position. Bundle it with the comparison to make it easy to for others to improve and iterate on it.
Various options are available for turning the screenshots into GIF images. A few examples:
Paint.NET: ['GIF Animations and Images' FileType Plugin]. Screenshots on this page use a Delay of 500, and set the loops to 0 (There's no reason why an image should stop animating).
Utilizing an [APNG converter] allows significantly better color quality, but locally available tools are rare.
- The exact resolution needs to be specified in the launch options.
