URP 2D Custom shader graph

Volandpro

Hello!
I want to create a custom shader using Shader graph tool in Unity.
When I create a new shader graph, my sprite is looking like this (it has black olutline):

If I use Spine Skeleton Lit shader, my sprite doesn't have this outline.

How can I achieve this result (without outline) with Unity Shader Graph? Thank you!

By default, Spine will export your atlas textures as Premultiplied alpha textures. See this section on the spine-unity pages how the two workflows differ in the export and import pipeline: spine-unity Runtime Documentation: Advanced Premultiplied vs Straight Alpha Import

Now you have multiple options:

A) Change the exported atlas texture format from Premultiplied alpha to Straight alpha in the atlas texture export settings.
B) Adapt the shader graph to Premultiplied alpha textures: either a) change the blend mode to additive blending Blend One OneMinusSrcAlpha, or b) un-premultiply the texture color after use by dividing texColor.rgb by texColor.a value.

Thank you!
Changing Premultiplied alpha to Straight alpha in the atlas texture export settings solved the problem.
