AI materials for Unreal Engine.
One surface or a whole pack.

No. You choose Single, Variations or Material Pack. In Material Pack, Prepare material list turns a scene brief into a proposed list to review and edit before generating. Numbering is optional; Separate cards also lets you write exact briefs yourself. A detailed description of one printed carpet is still one material. Lists are not padded to fill a count; packs support up to eight distinct materials. Ready results become selectable while the remaining materials generate.

No. One textured material includes Base Color, Normal, Roughness and Ambient Occlusion (AO) maps, plus its Unreal material recipe. A four-material pack contains four separate results, each with its own recipe and maps where needed. Procedural results can be recipe-only.

Standard renders a tileable Base Color, then derives Normal, Roughness and AO for the kind of surface you described: a printed design such as a road playmat stays flat colour, bricks and tiles keep their mortar recessed, and roughness follows the finish your brief asks for. Pro Engine adds an AI relief pass — an estimated normal map and height-based AO — for deeper relief on stone, brick, wood and cracked ground. Pro Engine renders all four maps (Base Color, Normal, Roughness and AO) at 2048x2048 (2K); Standard renders them at 1024x1024. Normal maps use the DirectX convention Unreal expects.

Standard generation costs 4 credits per material. Pro Engine adds 5, making it 9 per material. Pro Engine materials have a 2048x2048 (2K) texture and maps; Standard materials are 1024x1024. Four results cost 16 or 36 credits respectively; the full quote is shown before you start. Failed pack results are refunded individually. There is no additional draft or planner charge. Retrying a failed result is a new, separately charged generation. From image costs 1 credit per material, or 2 with AI relief maps. Repainting a model costs 4 credits; every account’s first repaint is free.

Yes, on paid plans. Choose From image, upload a PNG, JPEG or WebP of one surface (at least 512 × 512 px, up to 15 MB) and pick the square to use. Your image becomes the Base Color as it is; MaterialForge adds Normal, Roughness and AO maps for its surface type and writes the Unreal material. It costs 1 credit, or 2 with AI relief maps. Lighting, shadows and perspective in the photo are not removed, so flat, evenly lit, head-on shots work best. Images with transparent areas are refused before anything is charged; use an opaque texture that fills the frame. If the image is not a usable surface, such as a whole object, a scene or a person, the job stops and the credits are refunded.

Adjust Parameters changes the connected values exposed by a recipe, such as tint or UV tiling, and Surface Lab edits the texture maps themselves: relief depth, roughness and its variation, and ambient occlusion. Both preview live, spend no credits and save as a new result; the original stays unchanged. A saved preset can also be applied to several materials at once; only materials with a matching graph change, and each becomes its own new result. New Variation and Refine start a fresh full generation at 4 credits, or 9 with Pro Engine; Refine is not an image-preserving edit.

Yes, for free. Choose Paint a model in the product bar and pick a self-contained .glb file, up to 50 MB and 1.5 million triangles. It opens in your browser and is not uploaded unless you choose Save asset for later, which keeps a private copy in your account to reopen later (3 models on Starter, 20 on paid plans). Click a part, or pick its material slot, to give it the selected material; parts that share a slot change together, as they do in Unreal. Switch between Original and Look to compare, and use Save look to keep named looks such as New or Worn with the asset; their materials are saved to your library so a look reopens the same way. Parts without UV coordinates cannot show a material. To resize the pattern, change UV tiling in Adjust. Download GLB saves a copy of your model with the look as glTF PBR (maps, tint and UV tiling per slot, without Unreal graph effects beyond those), ready for Blender, Unity, Godot or a web viewer; it is a file download, so Starter uses its one free download and paid plans download freely. Your original file is never changed, and materials are not assigned to your asset in Unreal.

Yes, on every plan, and the first one is free. Choose Paint a model in the product bar, open your model, choose Repaint with a prompt and describe the new look, such as weathered steel with peeling green paint. Before anything is sent you see the exact image that leaves your browser: flat views of your model from 14 directions. Your .glb file is not uploaded. An image model repaints those views and MaterialForge projects the paint back onto the base colour of every part with UV coordinates, so the look stays consistent from every side; normal and roughness maps stay as they are. Your first repaint is free; after that a repaint costs 4 credits, refunded automatically if the result does not line up with your model (the free one is not used up either). Parts whose UVs repeat a texture repeat the new paint too, and parts without UVs keep their look. Download GLB writes the repaint into a copy of your model, and Download textures gives you the base colour PNGs. The Surface tab adjusts roughness, metallic, normal strength and a tint over the look, for every part or one slot; those settings go into the GLB and are saved with the look. Save look keeps the repaint with your saved model, so the look reopens repainted; until you save, the repaint is kept for 30 minutes so a reload can restore it for free.

Yes, on paid plans. Give a collection a shared style in Account → Materials or in the workbench: palette, scale, wear and notes. In Single mode, choose Add to a collection; the new material is generated with that style and knows the collection's existing materials, and only the new material is charged (4 credits, or 9 with Pro Engine). To make one material differ on purpose, fill in the difference and say why; the collection keeps its style. Add the result to the collection when you are happy with it. In Paint a model, Paint from a collection lets you choose a collection material for each slot. A shared style makes results more consistent, not identical.

Save keeps only the selected material in your private account library. Select and save each result you want to keep. Unsaved texture-based results have a recovery window of up to 24 hours in Account → Materials, where you can save them without regenerating. Saving one result does not preserve the other pack results.

Download Pack includes the successful results in numbered folders with recipes, available maps and a pack manifest. Apply Pack in UE5 uses the Cosindra desktop app and Unreal plugin to bring successful materials into your project. Applying costs no extra credits on any plan. File downloads require a paid plan after Starter’s one lifetime free asset download, shared across products. Download or save textured results before their recovery window expires.
