Parallax Occlusion Mapping Decals (Using Custom Decal Response) UE5

Описание к видео Parallax Occlusion Mapping Decals (Using Custom Decal Response) UE5

Many have wanted to use POM and decals together to add details to an object or environment, only to find that the built in node breaks if it is rotated in any way - making it unusable as a decal.
This is because POM relies on mesh tangents to render correctly, and the decal cannot sample them. In my last video, we learned how custom decal responses could be used to allow working tangent space normal map decals. Using the same technique, we can give POM the tangents it needs by offloading the POM to the underlying mesh material, and viewing decals as a vessel for general purpose data.
