Modular first-person arms for URP. 10 skinned pieces on one rig: gloves, sleeves and bare skin, clean and dirty variants, runtime dirt blending and the full Blender and Painter source.URP only shaders.Built and tested in Unity 6.0 (6000.0.82f1) with URP 17.0.4. All materials use custom URP Shader Graphs (skin SSS, dirt blending). URP must be active before import. The demo scene uses TextMesh Pro: Unity will prompt to import TMP Essentials.FPS Modular Arms Pack is a set of first-person arms built to be mixed. Pick a glove, pick a sleeve, add the matching skin piece and you have a loadout. Swap one piece and you have another.What’s inside• 3 gloves: standard, fingerless and semi-fingerless, 3 variants each• 2 sleeves: long sleeve and tactical jacket, 3 variants each• 5 bare skin pieces: full arms, arms, hands, fingers and three fingers, 2 skin tones• A clean and a dirty version of every variant• 85 ready-to-use prefabs and a demo sceneDirt you can controlEvery variant ships with three material setups: clean, dirty and blending. The blending shader moves between clean and dirty with a single float, per material, at runtime. Muddy gloves after a firefight, clean ones in the briefing room, same mesh.Skin that doesn’t look like plasticURP has no built-in subsurface scattering, so we wrote our own. The skin Shader Graphs use a custom SSS function driven by a scattering map.Built to be modifiedYou get the full source, not just the end result:• Blender 4.5 rigging scene with every piece weight painted• 32 Substance 3D Painter smart materials, one per variant• Low poly meshes with UVs and decimated high poly for baking• Every baked map: AO, normal, curvature, cavity, thickness, ID and moreMake your own colorways, rebake, adjust the skinning. It’s all there.One rig, UE5 hierarchyAll pieces share a single Generic rig that follows the UE5 Mannequin hierarchy, so it slots into pipelines built around that skeleton. This is a Generic rig, not Humanoid, and no animations are included.RequirementsUnity 6.0 or later with URP 17. HDRP and Built-in are not supported.Documentation and supportA full PDF guide is included.
