A black block appears in the layer's pixel settings.

Hello. I have a problem. Please look at the figure.

Expanded place. It will appear on the right side and the bottom side.

Even if the resolution is increased, it will not be solved.

This is the file.
This phenomenon also occurs in the image layer.

Wow, that is weird. I'm not sure where it's pulling the black values from...and the result is actually worse in a full render. (i.e., Moho Exporter vs. Preview Render.)

I'll see if I can get the devs to look this.

There's not actually any black. If you render a frame, use the Moho style eyedropper on the render window, and open the picker, you'll see that it is just lighter, less saturated fill color.

This is bound to happen with a high enough pixelation value.

I still think there's something odd going on here. The pixels should only be blending between the two colors and the pixelation seen on the left side looks correct. The pixelation on the right should more or less be a mirror of the right side.

In other words, it should be consistent all around the image and the pixels should blend between magenta and blue, not blue and less saturated blue.

Also, there is slight 'fade' within the darker blocks, which shouldn't be happening. Here's a Exporter Render that shows it a little more clearly.

I did a different render early this morning that showed an even more gradual L-to-R fade within the dark blocks. I'll see if I can reproduce that later.

As you can see, it is symmetrical at certain points, but true pixelation (which this effect is meant to simulate) actually moves from one pixel to the next, where this kind of crawling is expected because the source doesn't match a whole number of pixels.

Hmm, okay. I guess the keywords are 'which this effect is meant to simulate'. I assumed the transitional colors would based on anti-aliasing between the two colors but the effect appears to take motion vectors into consideration.

I guess it's meant to look more like a video mosaic effect rather than a low-res image upscale effect?

Yeah, the original request for this feature was to simulate 8-bit video game graphics. So, it's not just a low-res object...it actually lives in a low-res envelope.
