this is not 8% increase ... as it is in your picture (maybe 8% loader size increase) and not assembler...; this is 8% increase on the assembler:

graphics_set =
{
animation =
{
layers =
{
{
filename = "base/graphics/entity/assembling-machine-1/assembling-machine-1.png",
priority="high",
width = 214,
height = 226,
frame_count = 32,
line_length = 8,
shift = util.by_pixel(0, 2),
scale = 0.58
},
{
filename = "base/graphics/entity/assembling-machine-1/assembling-machine-1-shadow.png",
priority="high",
width = 190,
height = 165,
line_length = 1,
repeat_count = 32,
draw_as_shadow = true,
shift = util.by_pixel(8.5, 5),
scale = 0.58
}
}
}
},
I forgot to mention : The Assembling Machine increase size is 8% not the loader.
the script in aai loaders say increase the size of assembling machines by8% so that the loader will not stand in thin air.
