Hey Spine team,

Thanks for an excellent product and runtime. You guys are really great.

This is just a small bug that I quickly fixed locally, but I thought you'd want to hear about it. I recently switched from bilinear filtering for my project assets to Point mode, and noticed when I used my Mix and Match code that the remapped clone sprite would be set to Bilinear filtering, which is the default mode for a Texture2D in Unity, I believe.

The offending code starts at a call to the Extension method in AttachmentTools.cs: GetRemappedClone. The PMA version of the function that is then called, ToAtlasRegionPMAClone, respects the textureFormat and mipmaps setting, but doesn't handle the filtermode. To fix this, I adjusted the code by adding the line shown below.
public static AtlasRegion ToAtlasRegionPMAClone (this Sprite s, Shader shader, TextureFormat textureFormat = SpineTextureFormat, bool mipmaps = UseMipMaps, Material materialPropertySource = null) {
var material = new Material(shader);
if (materialPropertySource != null) {
material.shaderKeywords = materialPropertySource.shaderKeywords;

var tex = s.ToTexture(textureFormat, mipmaps);
tex.filterMode = s.texture.filterMode; // added this line
I haven't updated my runtime in a few months so forgive me if this is already known/fixed. You may also prefer to set the filterMode inside the ToTexture extension method instead. Cheers!

Good catch! This is actually still not fixed in the 3.8 branch. I've created an issue here: Thanks for reporting!
