Pixel Lab Blemish Pro earns its place in the toolfarm library for a focused job: 100 high-resolution roughness maps that add surface wear to renders. The 8k, 16-bit files and the option to stack maps make it a practical grab bag for artists chasing photo-real detail.
Pixel Lab Blemish Pro is a collection of 100 professionally designed grunge maps for adding realism to 3D renders in Cinema 4D. Each map drops into the roughness channel, where it applies scratches, smudges, fingerprints and grime across an object's surface.
All 100 maps are 8k resolution and 16 bit, and they're extremely detailed, so you can zoom in close and still get clean results. Every map tiles without visible seams apart from the halftone patterns, and you can stack multiple maps together to build up denser surface detail.
The pack works with any 3D render engine or application and requires 5.6 gigs of hard drive space. A demo video is available on YouTube. It was last updated in June 2023.
Pixel Lab Blemish Pro is best for cinema 4D artists who want to add scratches, smudges, fingerprints and grime to their renders through the roughness channel.
Pixel Lab Blemish Pro is completely free to download and use.
Pixel Lab Blemish Pro works with any 3D render engine or application, so the maps aren't tied to one renderer. Each is a roughness texture that you load into the roughness channel of your material, wherever that channel is available. The pack is used in Cinema 4D, but the maps themselves are standard image files. For guidance on loading them into your particular setup, the developer's page is the place to look.
Pixel Lab Blemish Pro requires 5.6 gigs of hard drive space. That reflects the size of the pack, which includes 100 maps at 8k resolution and 16 bit, high-resolution image files that take up considerable room. Make sure you have that space free before installing, and factor it in if you keep the maps on a drive alongside other texture libraries.
Pixel Lab Blemish Pro includes 100 maps, and all of them tile without visible seams except for the halftone patterns. That means most maps repeat cleanly across a surface without obvious edges, which helps when covering large objects. The halftone patterns are the exception and aren't seamless. You can also stack multiple maps to combine their detail into a single, denser roughness result.
Pixel Lab Blemish Pro is listed as free here in the catalog. Licensing terms can change over time, though, so before you rely on it for a project it's worth confirming the current terms directly on the developer's page. That page is also where you'll find the download itself, along with any details about how the 5.6-gig pack is distributed and what the current licensing arrangement looks like.
