Sorry, maybe this has already been discussed, but I could not find it. After the transition from Unity 2019.1 to Unity 2019.2.13f, the rendering of particles from the same material and texture with a unique Render Queue began to significantly increase SetPass Call, this does not happen if the Render Mode Mesh, but the effect ceases to fade so smoothly with Billboard.
In the previous version of unity Unity 2019.1, if one material and texture were assigned, the number of SetPass Call did not increase.
If any solution?
