How-to

Step by Step

The Head and Face

This is, undeniably, the most important piece. In the game, the face is the trademark. If the head doesn't look like a recognizable Roblox block, the rest of the costume will fail. The geometric shape (square, sphere, pear) must be precise. If the avatar uses the classic "Smile Face" or the new makeup systems recently released in the Marketplace, these facial details must be perfectly replicated. The proportion between the size of the head and the body must follow the game's stylization (general

Symbols and Logos

Many bundles and items in Roblox are defined by specific logos (e.g., the Noob symbol, the emblem of specific games like Adopt Me or Brookhaven). The presence or absence of these graphics is what differentiates a "generic block character" from your specific avatar. The application of these graphics must be impeccable

Torso Silhouette

The torso box dictates the posture. In the R6 style (6 parts), the torso is a single rectangle. In R15 (15 parts), it can have joints. Defining this base structure is vital so that the cosplay doesn't look just like a person dressed in baggy clothes, but rather an entity from the game. The way the shoulders connect to the arms is a key point of visual reading

Creation of the Base Pattern

Using Kraft paper or butcher paper, wrap your torso (chest and abdomen) slightly loosely. You do not want a tight fit, but rather extra volume to create the square effect. Mark the cut lines to create a front rectangle, a back rectangle, and two side rectangles. The goal is to transform the cylindrical body into a rectangular prism. Checkpoint: When wearing the paper pattern, it should allow you to breathe comfortably, but should already start to lose the curvature of the human waist

Transfer and Cutting of EVA

Transfer the pieces from paper to 5mm or 8mm EVA sheets (depending on the desired rigidity). Remember to add a seam margin or overlap of about 2cm to 3cm on all edges that will be glued. Cut the pieces using a sharp craft knife and a metal ruler to ensure perfectly straight lines and sharp 90-degree corners. Checkpoint: When placing the cut foam pieces together, they should fit perfectly forming a closed box, without gaps or exaggerated overlaps

Heating and Gluing the Edges

Heat the gluing edges with a heat gun at a temperature between 120°C and 140°C, moving the air constantly to avoid melting the foam. Apply high-quality contact glue to both surfaces. Wait for the drying time recommended by the manufacturer (usually when the touch is "dry to the touch") and join the pieces, pressing firmly. Start by gluing the sides to the front panel and, lastly, close with the back panel. Checkpoint: The structure should be rigid and maintain the square shape without the suppor

Refinement of Edges (Beveling)

To ensure the cosplay does not look like a crude shoebox, you must bevel the outer edges. With 80 or 100 grit sandpaper, tilt the craft knife or sandpaper at 45 degrees on the vertical edges of the box. This creates a "bevel" that simulates low poly lighting and prevents paint from chipping on sharp edges. Checkpoint: Running your hand over the edges, they should be smooth and rounded at a microscopic level, but maintaining the 45-degree angle at a macroscopic level

Opening and Sealing the Surface

For the EVA to accept paint and look like smooth plastic, we apply a layer of sealer. You can use a mixture of white glue of your choice and water (50/50) with a brush, or Mod Podge. Apply 3 to 4 thin layers, letting dry completely between each one. Then, sand lightly with 220 grit sandpaper to remove irregularities. Checkpoint: The surface should be smooth, without the open pores of the foam visible, and ready to receive primer or acrylic paint
