Hi! I was actually spamming S in the video XD There was an instant change function, but it was laggy on textures like 2048x2048 in size. I learned how to scale down the base texture, so instead of just applying a pixelate effect on the original image, it actually scales it down. It shouuld be enough to implement the instant change option! I'll try to make this update tomorrow or in 2 days! Sorry for the inconvenience :C
