just download your uploaded version, the psd is there with the masks.
Yeah, but it's outdated; I had reconstructed the workspace to accommodate improved accuracy in the rendition of perspective and dimensions for the grid nodes. In other words, I had drawn them to look better and had a bigger canvas!
It won't take me too long to draw the wireframes again, but it's annoying to lose any of the precious time I have these days.
ahem, if this were sc you wouldnt have to make masks cause sc generates mask automatically
GM doesn't incorporate sprite masks, I use them in photoshop to apply textures to shapes. Colouring within the lines if you will.
