Description
X-Decal Material (XDM) is a special triplanar projection decal material built to eliminate the stretching and streaking normally seen when decals hit non-flat surfaces or wrap across mesh intersections. Apply a single decal to cover every side of an object without fighting projection angles, and use the adjustable edge mask to turn any square texture into a clean decal — or keep visible corner boundaries when that's the look you want.
XDM includes Normal Motion support, a color-only decal mode for fast dirt, puddles, stains, and grime, a roughness channel selector, and random rotation for edge mask placement — plus 4-quadrant atlas material support and full X/Y/Z axis masking for precise control over where and how decals apply.
One of XDM's most powerful features is Decal Mesh ID Masking: assign ID numbers to meshes so that only meshes sharing an ID receive a given decal. Default Unreal Engine only lets you flag a mesh as able to receive decals or not — there's no way to art-direct different decals onto neighboring meshes. XDM makes that level of control possible, so you can place one decal in one area and a completely different one right next to it.
XDM also includes the Decal Sniffer tool at no extra cost — a radius-based selector that locates and highlights decal actors in your scene, including hidden ones the Outliner won't easily surface, so you're never hunting blind for a decal you know is somewhere nearby.
XDM is built to work hand-in-hand with XDP (XDecal Painter). A random function drives range-based variation in brightness, density, and edge shape, so a single decal can generate a wide spread of natural-looking results instead of an obvious repeat. Pair it with XDP's scattering tools and the Normal Correction parameter keeps normals accurate even as brightness and density randomize across a scene.
👉 XDecal Painter is built to complement XDM, letting you paint decals directly in the viewport — like the Foliage Tool, but for decals — with full precision and speed.
*Xdecal (not the Xdecal stencil masking feature) is included as bonus material in Extile Plus
**Works with any texture or decals including Megascans
