Decal Splines lets you draw continuous decals like roads, paths, blood trails, cracks, track and road markings onto any 3D surface with any orientation. A seamless decal is formed along a spline.The main shader uses stencil buffer bit# 8. An alternative bit can be used by altering the shader code. A non stenciled shader is provided as well, however this one may have visual artifacts when used with transparency.On Mac/Metal URP builds artifacts can show up due to bugs in this Unity Pipeline.To solve this disable “Generate Mipmaps ” on any texture used and set Normal Blend to High.✔️How to usePlacement works intuitively in the scene view.
