Corner Store Props Starter

Version 1.0.0, released 7 November 2026 by Socket & Pivot.

The Props Starter contains 35 props for dressing a modern corner shop, and most of them do something when the player uses them. Doors on the fridge, drink cooler, ice merchandiser, lockers, fuse box and bins open on their hinges. Drawers slide, the card reader turns towards the customer, and boxes, baskets, the mop bucket and the wet-floor sign can be carried. Shelves, coolers, the freezer and the back-room rack fill themselves with product from a data table, and players can take items out and put them back.

The free Corner Store Sampler is part of this kit: its ten props are included among the 35 and use the same asset names. All brands on the packaging are fictional, and no generative AI was used to make the meshes, textures or label artwork.

1. Contents

Fixtures

Back room

Exterior

Products

Every product is a mesh plus a row in DT_StoreItems. Any product can stock a shelf slot, and the player can pick it up, carry it and put it back.

Systems and maps

The download contains an Unreal Engine project, a Blender asset library with 37 assets (the soda can appears once per flavour), and FBX files with their textures for other software.

2. Compatibility

3. Installation

Opening the Unreal Engine project

Open UE5/SP_CornerStorePropsStarter/SP_CornerStorePropsStarter.uproject in Unreal Engine 5.8. The editor starts on L_PropsStarter_Demo, and Play drops you at the shop entrance. Unreal compiles shaders for the kit's materials the first time the project opens, so that start is slower than later ones.

Adding the props to an existing project

1. Close the project.
2. Copy UE5/SP_CornerStorePropsStarter/Content/SocketAndPivot into the project's Content folder, keeping the folder name.
3. Open the project and load SocketAndPivot/CornerStore/Maps/L_PropsStarter_Demo.

If the free Sampler is already in the project, allow the copy to replace its files. The Starter contains every Sampler asset under the same name.

The demo maps carry their own GameMode override, so no project settings need to change. Unreal Engine 5 projects use Enhanced Input by default. For an older project that still uses the legacy input classes, open Project Settings > Input and set Default Player Input Class to EnhancedPlayerInput and Default Input Component Class to EnhancedInputComponent.

Blender

In Edit > Preferences > File Paths > Asset Libraries, click Add and choose the Blender folder from this download. The Asset Browser then lists the props under Corner Store, in the catalogues Fixtures, Back Room, Exterior and Products. Append (Reuse Data) is the recommended import method, and Link also works. The Showcase collection in the .blend file places every asset in a row for a quick look.

FBX files

There is one FBX file per prop in Exports/FBX, in centimetres with Z up. In Blender's axes each prop faces -Y, which becomes +Y after import into Unreal Engine. Each file also contains the UCX_ collision hulls and SOCKET_ sockets that Unreal Engine reads on import; other software can ignore or delete them. Textures are in Exports/Textures, and Exports/materials.csv gives the textures and settings for each material.

4. Demo controls

When you look at an object you can use, its edges light up in chartreuse and its prompt appears beside the crosshair.

Core is identical across Socket & Pivot kits. A project with two kits installed shares one Core folder; keep the newer copy.

6. The interaction system

Every interaction in the kit goes through two Blueprint components.

BPC_Interactor sits on the player pawn. It traces a line from the camera twenty times a second, on the Visibility channel and up to TraceDistance (250 cm by default). The first actor hit that owns a BPC_Interactable becomes the focus. Its meshes are highlighted, and GetPromptText returns the prompt for the HUD.

When the player presses Interact, TryInteract resolves the action. With empty hands, a carryable actor in view is picked up, and anything else runs the focused component's Interact function. With an item in hand, the outcome depends on what is in view:

BPC_Interactable is added to anything usable and has these settings:

The highlight lives in the materials. Focusing an object writes 1 into Custom Primitive Data index 0 on its meshes, and M_SP_Master and M_SP_Glass respond with a chartreuse Fresnel rim and a 16 % tint. Since no overlay or post-process pass is involved, Nanite meshes highlight like any other. Your own materials can take part by adding a scalar parameter with Use Custom Primitive Data enabled at index 0.

7. Shelf slots

A BP_ShelfSlot is one row of a single product. It attaches to a socket whose name starts with Slot_, and its construction script works out how many units fit from the product mesh's bounds and the row's Facings value.

During play the player can take any unit, which spawns a BP_Pickup in their hands, and return it to an empty position in a slot of the same product. A slot that stocks something else shows no prompt and refuses the item. The gondola's back-side sockets are turned 180°, so slots attached to them face the second aisle.

To place a slot by hand, drag BP_ShelfSlot into the level, set its parent to the fixture and its parent socket to the slot you want, and reset its relative location and rotation. From a Blueprint, use Attach Actor To Component with Snap to Target. Every stocked fixture in L_PropsStarter_Demo is set up this way.

8. Placement sockets

Some fixtures carry sockets for placing other props. Attach the prop to the socket with Snap to Target.

9. The product data table

DT_StoreItems uses the struct S_SP_StoreItem:

10. Using your own character

Add BPC_Interactor to your player pawn and call TryInteract from your Interact input. Your interface can read GetPromptText or listen to OnFocusChanged. BP_SP_DemoHUD is only there to make the demo playable.

11. Extending the kit

Adding a product

Import the mesh with its pivot at the centre of its base and its front facing +Y, add a row to DT_StoreItems, and use the row in a BP_ShelfSlot or BP_Pickup.

Adding a variant of an existing product

Duplicate the product's label material instance and give it a new BaseColorMap. A new data-table row then points OverrideSlot at the label's material slot and OverrideMaterial at the new instance.

Making another actor interactive

Add a BPC_Interactable. A door, drawer or lid needs MovingPart set in the construction script, as the kit's Blueprints do, plus an OpenRotation or OpenOffset. Other behaviour, such as a light switch, can be bound to OnInteracted.

Making a mesh carryable

Create a child Blueprint of BP_Pickup and set its PickupMesh. The kit's boxes, mop bucket and wet-floor sign are built exactly like this.

Creating a new surface

Make a material instance of M_SP_Master, or of M_SP_Glass for transparent surfaces:

Changing the highlight colour

Adjust HighlightColor and HighlightStrength on the master materials, or override them per material instance.

12. Technical specifications

13. Known limitations

• The kit has been tested in Unreal Engine 5.8.3 and Blender 5.2 LTS only. Section 2 has the details.
• Interactions are designed for single-player games and do not replicate over a network.
• There are no sound effects.
• The kit contains props and their interactions only. It has no customers, economy or save system.
• The demo HUD is a minimal Canvas HUD with English text. Prompts are stored as Text and can be localised.
• Interaction uses a single line trace, so aiming exactly at the 8 mm gap between two products reaches the shelf behind them.
• Reaching into the chest freezer works best from right beside it, looking down over the rim.
• Only materials that read Custom Primitive Data index 0 show the focus highlight. Both included master materials do.
• Collision hulls and sockets are left out of the Blender library. The FBX files include them.
• GLB and USD exports are not part of this version.
• Baked lighting has not been tested, and the meshes have no dedicated lightmap UV channel.
