That is an XP resource, not an MV resource. It is a simple character sheet that you would turn Stepping Animation on to activate.
If you want to use it in MV you will need to reformat it - either as an animation (5 frames per row, each one has to be a specific size), or probably the easiest way is to swap the columns/rows around, so the animation sequence goes down instead of across. Then you can just use a move route that changes the event's facing direction to animate it - this way YOU are in control of the timing and aren't leaving it to the stepping animation and hope you can time it right to move to the next sequence right as the previous one finishes.
There's a lot of whitespace there - do you need the big gaps above/below the rings? If not, just work out the size of each ring, and make the template 12x the width and 8x the height. Whether you want/need to upscale depends on where you're using it.
The chevrons locking don't require animation. You can have 7 event pages with a different one on each page, and condition the pages by a variable. Each time you want to lock the next one, just increment the variable.
If that was shared on an RPG Maker forum, I imagine there should have been some very detailed instructions on how to use it?
PS - Don't double post (mlogan pointed that out earlier). If you need to add something, edit your last post.
Across is the walk animation. You could get the engine to display each frame separately or the extra could even be empty frames if you want but duplicating them across is easier. The important part is that all the frames are there, because the engine can't just guess at whether or not the width is for 3 frames or just one. It's the trade off for being able to make the frames any size.
Hey @Pharonix, just wondering what you're up to lately and if you've had an opportunity to check out the LTBS thread in the past few days...(a couple of us could really use your expertise). Hope you are well and Happy Thanksgiving!
