They work correctly in URP but trigger an SRP compatibility warning in the Asset Store Validator. This does not affect functionality or performance. A URP-native skybox will be provided in a future update.(Optional) AI Cloud ModeThis package includes an offline dialogue system using JSON files that works entirely inside Unity without any internet connection.For developers who want more advanced AI-powered NPC conversations, the system can optionally connect to an external AI backend.Online AI features may require:API key configurationInternet connectionSubscription or usage-based billing depending on the external service usedOffline mode works independently and does not require any external services.More information about the cloud service can be found here:Wiki/CloudSupport:Email: info@metamix3d.comWebsite: www.metamix3d.comHorror Environment46 PBR texturesTexture resolution: 2K / 1KPolygon range: 264 – 85,898 triangles14 prefabs + 1 terrain mesh3 LOD levels on selected assetsUV mappedPBR materialsNo riggingNo animations includedSupports URP and Built-in Render PipelineUnity 2021.3 LTS or newerAI NPC System6+ NPC / system prefabsNPC prefab systemNPC chat componentDialogue UIJSON dialogue loaderWorld knowledge systemProximity-based NPC interactionInspector-based configurationRuntime dialogue interaction logicSupports URP and Built-in Render PipelineUnity 2021.3 LTS or newerENGINE COMPATIBILITYUnity 2021.3 LTS or newer.RENDER PIPELINE COMPATIBILITYSupported:Universal Render Pipeline (URP)Built-in Render PipelineHDRP is not currently supported.CORE SYSTEMS INCLUDEDNPC prefab systemNPC chat componentDialogue UIJSON dialogue loaderWorld knowledge integrationProximity-based interactionInspector-based setupRuntime dialogue interaction logicExample setup workflowDemo sceneDIALOGUE SYSTEMJSON-based offline dialogueEditable dialogue filesLocal dialogue workflow inside UnityNo internet connection required for offline modeOptional external AI integrationNPC SETUPDrag-and-drop NPC prefab workflowInspector-based component configurationDialogue file assignmentChat UI assignmentNPC characteristics configurationInteraction settingsOptional API Key and NPC ID configuration for cloud AI modeSAMPLE CONTENTExample NPC prefabsExample JSON dialogue filesExample world knowledge entriesDemo sceneSample dialogue configurationSCRIPTSC# scripts includedRuntime dialogue handlingJSON loadingProximity interaction logicWorld knowledge integrationInspector workflow supportedDOCUMENTATION INCLUDEDQuick Start GuideInstallation and setup guideNPC configuration guideOffline dialogue setupWorld knowledge setupExample usage documentationOptional cloud AI integration guideTARGET USERSIndie developersSolo developersPrototype teamsTechnical designersHorror game developersRPG and adventure game developersDevelopers building interactive NPC systemsDevelopers who want offline dialogue with optional AI-powered conversations
