Hi, We are on Unity 2020.1 and HDRP 8.2. We are trying to render some decals with additive alpha blending. However, the decal master node seems to only support the normal Alpha blending.
Is there a way to modify the Decal Master node source code to support additive alpha blending?
I tried to modify the output shader code of shader graph and changeged the “Blend” state to “One One, One Zero” but I did not get satisfying additive blending results because the colors were much dimmer compared to the additive blending in the unlit shader.
On the left side is the decals projector with the decal shader I modified. on the right is a simple plane with unlit shader with additive blending.
Thank you!
