Complete Game Asset Workflow: The Briefcase

Master baking tangent space normal maps by aligning bake and render math, manage smoothing groups with edge padding to prevent artifacts during unwrapping.

Unwrap the low-poly case using the text tools script to apply flatten mapping with checker textures. Organize UV shells and stitch seams to minimize distortion.

Organize and unwrap interior asset geometry for clean, readable textures by adjusting UV tiling, padding, and seams; stitch and detach faces, optimize density, and align edges for efficient texture painting.

Explore unwrapping the exterior pieces of the briefcase by detaching, stitching, and splitting UVs, adjusting seams for curved and flat faces, and packing the map for clean, accurate texture placement.

Choose a texture sheet between 512 and 2048 pixels, using a 2k by 1k rectangle, and pack the largest objects with padding, then render to test density.

Learn to mirror and duplicate overlapping elements of the briefcase asset, align parts, test bake results, and handle inverted normals during mirroring.

Apply a multi-sub material to bake, assigning distinct diffuse colors to subobjects so high-poly and low-poly regions project independently, keeping parts like the latch and the case separate.

Detach faces to ease projection on the Lopate model, verify triangulation and normals, then unwrap UVs and align materials to merge overlapping geometry for a seamless bake.

Render selection masks to isolate high-poly areas on the texture sheet with a magic wand, then bake a diffuse map with unique colors for wires, straps, and foam.

Develop a practical texturing setup by organizing layer sets for diffuse, normals, and specular maps, using multiply blending and Photoshop automation scripts for quick, one-button workflows.

Learn to block out basic colors in Photoshop using mask, diffuse channel, and the magic wand; create layer sets for exterior and foam, apply masks and fills, and refine selections.

Texture the exterior case by extracting and layering scratches from a photo source, masking and blending for authentic edge wear, and adjusting diffuse and specular depth.

Create a refined case specular map by enhancing highlights, layering textures and scratches, and painting controlled dirt to deepen depth and realism in metal surfaces.

Create film material textures by tiling a photo source, adjusting highlight tones, and blending folded brown paper bag textures in specular and diffuse channels.

Create tape details and handwritten labeling on four blocks using texture overlays, photo textures, levels, and normal maps, achieving a realistic C4 prop look.

Apply a dirt pass on the foam, diffuse edges with a soft brush, then adjust tones to a warm olive plastic look and chrome for the lock cylinder.

Export the completed briefcase prop, convert to a static mesh, import into UDK, create a material with diffuse and specular maps, set collision, and prepare a portfolio-ready report.

Set a dark gray viewport background and a balanced fixed-camera lighting to highlight materials and shadows, then capture a high-resolution viewport render with grab viewport and Photoshop tweaks.

Conclude with a game asset that goes from concept art to running in a level within a 9 to 5 workday, balancing asset quality and production time, plus texture painting.
