Only difference is that blending mode in the shader is different, but from the user's perspective the ShaderGraph shader acts like alpha-blended shader. Note: the blend modes are ignored if logical blend operations or If the VFX Graph sorts particles for the system, it uses an additional compute pass and bases the sorting on each particle's distance from the camera. The main difference is that the standard shader uses three different textures to represent a single layer. In the scene view it works just fine, but in the game view alpha blending doesn't work anymore. 3. You can see the vector4 (pink) output from the sample node being transformed into a vector3 (yellow) effectively discarding the transparency (alpha). additive can be faster than standard alpha blending for a software related reason: additive blending is commutative and requires no app-side primitive sorting, whereas normal alpha blending requires a back to front sort before draw call submission, to give the expected results.
