Chinese character rendering issues about msdfgen HOT 5 CLOSED

Post pictures.

from msdfgen.

This image is rendered by a 32 * 32 size texture.

This image is rendered by a 64 * 64 size texture. The hole is very small in the middle of the image. But when I use OpenGL to render this, a few holes appeared.

The lines in the font are way too thin for low resolution distance fields. Every line should be at least 1 or 2 pixels thick in the distance field in order to be encoded properly.

When I use a 128 *128 size texture, this problem disappeared. Thank you.
By the way, is there any way to solve this problem when using a low-resolution SDF texture?

You would have to make sure that the opposite edges that are close together have different colors in the MSDF scheme, but since there are only 3 available colors and you also need to switch them at corners, it may not be possible to satisfy both constraints. It is likely possible to generalize MSDF to 5 or more colors (channels), which would require multiple texture lookups, but I haven't tried implementing this.
