Happy to finally share with you my black version of the animated arrow signs based on the ones by Nadeo.
These were already made more than 2 months ago, although the locators for transparent webm did not work, but has been fixed today!

Here are step-by-step instructions:
Extract the contents of the .zip file into Documents\Trackmania\Skins\Any (Trackmania may be Trackmania2020 on your PC).
In the "Any" folder, check that the Advertisement1x1, Advertisement1x2, and Advertisement1x4 sub-folders have Bottom_B, Left_B, Right_B, Top_B, and Off_W.tga files, along with similarly named files that end in .loc.
Open Trackmania.
Create a new track or edit an existing track.
If you don't already have any signs in your track, add a sign from the block folder 6-3-1-X, 6-3-2-X, or 6-3-3-X (X could be a folder number between 1 and 3) or the item folder Official-2-3-X.
Click the paint bucket icon on the bottom or press the F5 key to enter Skinning Mode.
Click on a sign in your track.
In the list that pops up, select "Off_W" (or any name for a lightly colored background) and then any name that starts with + and ends with _B. (The names you want may be on different pages of the list.)
