Legacy GM Is it possible to edit game maker texture pages like a surface?

For example, if you wanted to tint/change the game environment, you could redraw all the sprites in their new form directly to the texture page, rather than doing it in real time every step using a shader or even image blend.

I'm sure this could lead to other problems, similar to the problems you'd get with surfaces not existing randomly. But is this even possible to begin with? Without implementing an entirely custom sprite engine like this one.

I'm using studio not 2 btw.


Sadly, no. You can create a surface that is a complete copy of original surface and use it for drawing with same UVs instead though. It's same in GMS2.
It's pretty sad because editing original texture can be really useful in some cases. I had to go with copy surface for my palette system before.
