I have been looking around online for a tutorial or information on how to flip a card horizontally in MSE but the best i could find was a console command flip_horizontal(input: image) from the old website. I have been unable to get that command to work suggesting that i need to do more, only thing is that i have no idea what i need to do. could someone please help me with this? the goal is to flip the card so i can print them on transparency paper and stick them to an empty foil. i have tried other apps to try and flip the image but when i export the card image it never prints properly (the size is never correct) unlike when i print directly from mse (the size is always correct).
Maybe you will use a third-party video editor or image editor? It is not entirely clear what you want to achieve, but in any case, there are many editors, but one videoeditor.com/ - really nice and you can achieve this.
Do you want to mirror the entire card, or just the frame and image? - If you wan't to mirror the entire card, text and all... WHY? Anyways, just use a photo editing software or Paint.NET or somthing after the render is done. - If you just want to flip the frame, there is probably a template that does something like that, but probably only for the normal M15 frame. If you need it for another frame, just edit the template to fit your needs.
- If you want to flip the image, just do so before using it in MSE.
And why would you want to mirror magic cards anyway? I know a way of making proxies that would reqire it, but you don't do the mirroring in MSE, and we don't support proxying here either (at least we didn't last time I checked).
