# BP Random Assembly BP\_RandomAssembly Is an actor which allow you to read a Random Assembly definition data asset and output static meshes (Instancers). It can be found here:

/Game/PCGRandomAssembly/Blueprints/Actor/BP_RandomAssembly

As almost all settings of the tool are defined in the[ Random Assembly Definition](https://cgtoolbox.gitbook.io/cgtoolbox-docs/pcg-random-assemblies/random-assembly-definition) data asset, the actor has very few parameters:

If False, the seed will be fixed, and can be changed manually or using the "Generate" button.

**Seed:** The random seed used by the random assembly PCG. This will be automatically updated if seed from position option if True. **Self Pruning Factor:** If any variant as its self pruning option to True, this value will be used by the Self Pruning node as "Radius Similarity Factor". **Direct Spawn Non Matching Variants:** If True, all the actors from the PCG data which don't match with any variant tags, will be spawned directly, before the variants evaluation. Meaning they will be available as collision data for all variants. If False, they will be spawned on the same time, after all variant evaluations. **Debug Info:** If True, print out some debug info in the output log (tags not found, tags being processed etc.). ```log LogPCG: [BP_RandomAssembly_C_2 - Print String_3]: [PCG_AssemblyVariantBPWrapper::Print String_3]: ---- Processing tag: Bench ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_41]: [PCG_AssemblyVariantBPWrapper::Print String_41]: 4 Point(s) with current tag LogPCG: [BP_RandomAssembly_C_2 - Print String_19]: [PCG_AssemblyVariantBPWrapper::Print String_19]: ---- End of tag processing. ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_3]: [PCG_AssemblyVariantBPWrapper::Print String_3]: ---- Processing tag: Table ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_41]: [PCG_AssemblyVariantBPWrapper::Print String_41]: 1 Point(s) with current tag LogPCG: [BP_RandomAssembly_C_2 - Print String_19]: [PCG_AssemblyVariantBPWrapper::Print String_19]: ---- End of tag processing. ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_3]: [PCG_AssemblyVariantBPWrapper::Print String_3]: ---- Processing tag: Plate ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_41]: [PCG_AssemblyVariantBPWrapper::Print String_41]: 8 Point(s) with current tag LogPCG: [BP_RandomAssembly_C_2 - Print String_19]: [PCG_AssemblyVariantBPWrapper::Print String_19]: ---- End of tag processing. ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_3]: [PCG_AssemblyVariantBPWrapper::Print String_3]: ---- Processing tag: Bread ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_41]: [PCG_AssemblyVariantBPWrapper::Print String_41]: 5 Point(s) with current tag LogPCG: [BP_RandomAssembly_C_2 - Print String_19]: [PCG_AssemblyVariantBPWrapper::Print String_19]: ---- End of tag processing. ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_3]: [PCG_AssemblyVariantBPWrapper::Print String_3]: ---- Processing tag: Pie ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_41]: [PCG_AssemblyVariantBPWrapper::Print String_41]: 3 Point(s) with current tag LogPCG: [BP_RandomAssembly_C_2 - Print String_19]: [PCG_AssemblyVariantBPWrapper::Print String_19]: ---- End of tag processing. ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_3]: [PCG_AssemblyVariantBPWrapper::Print String_3]: ---- Processing tag: Drinks ---- LogPCG: [BP_RandomAssembly_C_2 - Print String_41]: [PCG_AssemblyVariantBPWrapper::Print String_41]: 10 Point(s) with current tag LogPCG: [BP_RandomAssembly_C_2 - Print String_19]: [PCG_AssemblyVariantBPWrapper::Print String_19]: ---- End of tag processing. ---- ``` *** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
