Ocd (One Click Damage) ranks among the popular add-ons in the superhive library for turning procedural wear and damage into a click-driven, non-destructive workflow. Because the approach is fully procedural, damage stays editable and layered, and the HERO Module adds further detail on top.
Ocd (One Click Damage) is a Blender add-on for applying procedural wear and damage to mesh objects. It works on single or complex meshes, adding effects that range from subtle wear on new surfaces to deep scars, and suits stone, concrete, wood and brick structures.
The add-on is fully procedural, so changes can be made at any time. Damage stacks as layers with full control, masks let you erase damage where it isn't wanted, and Sync Damage transfers effects between objects for consistent damage or noise types. A pattern changer switches noise patterns with a single button, and materials can be assigned specifically to damaged areas. The interface offers sliders for beginners alongside advanced parameters for professionals.
The HERO Module adds further detail to objects. No models or presets ship with the add-on; the showcased effects are built in Blender using its built-in procedural textures. This 2.5.0 release requires Blender 4.5.
Ocd (One Click Damage) is best for artists adding procedural wear and damage to stone, concrete, wood and brick structures in Blender.
Ocd (One Click Damage) is completely free to download and use.
Ocd (One Click Damage), in its 2.5.0 release, requires Blender 4.5. The add-on is built around a fully procedural workflow, letting you make changes at any time, combine damage as layers, and erase areas with masks. For the exact supported versions and any requirements, check the developer's page, since Blender add-ons are tied to specific releases and 4.5 is the stated requirement for this version.
Ocd (One Click Damage) does not include any models or presets. The showcased effects, such as wooden planks, brick walls and ancient ruins, are created in Blender using OCD 2.5 with its built-in procedural textures. The add-on applies procedural wear and damage to your own mesh objects rather than shipping ready-made assets, so you provide the base geometry and OCD handles the damage, masks, layering and material assignment on top.
Ocd (One Click Damage) is listed as free in this catalog. Licensing terms can change, so check the developer's page for the current details before downloading. Functionally, the add-on covers procedural damage, masks, layered damage, Sync Damage for transferring effects between objects, a pattern changer, material assignment to damaged areas, and the HERO Module for extra detail. A demo video is available if you want to see more before committing.
Ocd (One Click Damage) includes Sync Damage, which transfers damage effects between objects for consistent damage or noise types. Alongside it, damage can be combined as layers with full control, masks can erase damage, and a pattern changer switches noise patterns with a single button. Materials can be assigned specifically to damaged areas, and the whole workflow is fully procedural, so adjustments can be made at any time.
