Hello, when building on an android phone, the normal map's red or green channel flip or otherwise have incorrect values, depending of the orientation of the object (or the face). Provided that there is no PBR graph anymore, I use Lit Shader instead. Fixed it! Turns out it was an issue with the alpha mapping (and simplified the graph as well by only using multiply and add) In case someone else finds themselves with something similar, make sure to first check if your alpha maps are: - Not overlapping other alpha maps. If I export as DirectX in Substance Designer, the normals are correct in HDRP, or if I export as OpenGL and multiply Y by -1 (or use the Flip node for the Green channel only) in an HDRP Lit Shader Graph, the normals appear correct. See in Glossary Graph gives instant feedback that reflects your changes, and it’s simple enough for users who are new to shader creation. In our shader, we’ll add a property to sample a normal map, and we’ll scroll it with time to give an impression of movement to our water. Posts: 73.
