Hi everyone!

My texture size is 64x64pix so the image filter is easy to see

i use the aistandardsurface shade and connect the file's alpha channel to aistandardsurface's Opacity A BanG channel and also closed the polyShape's arnold Opaque

when i closed the arnold texture filter of file,it only closed the color filter but not a Opacity cut geo

as you see the image edge blurred

I have the same problem, the only way I worked around was by enlarging the alpha texture to 4096x4096 with nearest-neighbour resampling in photoshop.
