SPOCK earns its place in the superhive library as a Python-based packer built after geometry nodes proved unworkable for the task, relying on instances to pack objects onto faces quickly.
SPOCK is a structured greeble packing and generation tool for Blender from Chipp Walters. It packs objects from distinct collections onto a face or selected faces, using instances for speed and 10 different packing algorithms — you can pick one or let SPOCK choose. Objects pack next to each other without overlapping while staying contained within a designated perimeter.
It uses the same DPACKS as simple sci-fi FLEX; DPACKS are collections of mesh objects, and you can create your own. A DPACK browser loads collection sets from your library, and it ships with a SCIFI DPACK containing several collection sets. SPOCK suits greeble and nurnie effects along with structured control panels and sci-fi interiors, and gives more control over the final layout than simple sci-fi FLEX.
A layered workflow lets you save packed instances into new collections, reload their settings, toggle collection visibility, and convert instances to meshes. It includes a multi-material and an edge wear material stored in KPACKS for use with KIT OPS PRO or KIT OPS FREE, plus a utility for globally swapping materials. You can set a maximum instance count when packing, and detailed documentation and Discord support are available.
Spock: Structured Scifi Packer is best for blender artists creating hyperdetailed sci-fi props, greeble and nurnie effects, and structured control panels or sci-fi interiors.
Spock: Structured Scifi Packer is completely free to download and use.
Spock: Structured Scifi Packer uses the same DPACKS as simple sci-fi FLEX. DPACKS are just collections of mesh objects, so you can build your own alongside the ones included. A DPACK browser loads collection sets from your library, and the addon ships with a SCIFI DPACK containing several collection sets to get started. You can point preferences at any folder to store your DPACKS, and third-party DPACKS created by the developer and others are available on the developer's page.
Spock packs objects from distinct collections onto a face or selected faces using ten different packing algorithms — you can choose one or let SPOCK pick for you. Objects are placed next to each other without overlapping while staying contained within a designated perimeter, and the addon works with instances for speed. When packing, you can set a maximum number of instances so Blender is less likely to crash on heavy scenes.
Spock includes a multi-material that lets you assign different materials to each instance it's applied to, along with an edge wear version. These materials are stored in KPACKS, which you can use with KIT OPS PRO or KIT OPS FREE. The addon also adds a utility for globally swapping materials, and its layered workflow lets you save packed instances into new collections, reload their settings, toggle visibility, and convert instances to meshes.
Spock: Structured Scifi Packer is listed here as free, though licensing terms can change. For current pricing and license details, check the developer's page. The addon comes from Chipp Walters and is built for Blender as a Python addon, shipping with a SCIFI DPACK, multi-material and edge wear materials, and several utilities. It also comes with detailed documentation and full support on Discord, so you can confirm what's included before installing.
