Menempatkan Light Probesprobe cahaya menyimpan informasi tentang bagaimana cahaya melewati ruang di tempat kejadian Anda. Koleksi probe cahaya yang diatur dalam ruang tertentu dapat meningkatkan pencahayaan pada objek bergerak dan pemandangan LOD statis dalam ruang itu. More info
Lihat di Glossary atas tingkat besar dengan tangan dapat memakan waktu. Anda dapat mengotomatiskan penempatan probe cahaya dengan menulis editor Anda sendiri scriptsSepotong kode yang memungkinkan Anda untuk membuat Komponen Anda sendiri, memicu peristiwa permainan, memodifikasi sifat komponen dari waktu ke waktu dan menanggapi input pengguna dengan cara apa pun yang Anda sukai.

Lihat di Glossary. Skrip Anda dapat membuat GameObjectObjek mendasar dalam adegan Unity, yang dapat mewakili karakter, props, pemandangan, kamera, waypoints, dan banyak lagi. Fungsi GameObject didefinisikan oleh Komponen yang melekat padanya. More info
Lihat di Glossary baru dengan komponen LightProbeGroup, dan Anda dapat menambahkan posisi probe secara individual sesuai dengan aturan yang Anda pilih untuk program.
Misalnya, skrip ini dapat menempatkan Probe Cahaya dalam lingkaran atau cincin.
