Material hilang pada pratinjau unggahan model dapat terjadi ketika efek material pada pratinjau tidak sesuai setelah proses unggah model selesai.
Saat menunggu unggahan model selesai, efek material pada pratinjau model terlihat tidak benar.
Efek pratinjau unggahan yang diharapkan adalah seperti ini
Namun, hasil sebenarnya menjadi seperti ini
Atau seperti ini (blok warna-warni)
Masalah ini dapat disebabkan oleh beberapa hal berikut
1. File .max diunggah tanpa file tekstur2. Tekstur hilang (termasuk kesalahan jalur dan perubahan nama tekstur)3. Pengaturan renderer (jarang terjadi, yaitu saat material override diaktifkan pada renderer)4. Diffuse level5. Normal model6. Terdapat multi-sub materials pada file sumber model 3Dmax (material campuran)
Jika model tidak memiliki tekstur (material tidak menggunakan tekstur), Anda dapat mengunggah file .max saja. Jika ada tekstur, unggah model dalam bentuk paket diperlukan karena proses pengemasan akan menyertakan tekstur yang digunakan pada model.
Langkah:
a) Pertama, periksa efek model di 3ds Max untuk memastikan hasilnya sudah sesuai. Jika tekstur hilang, jalurnya salah, atau model menggunakan multi-sub materials, model akan terlihat hitam di 3ds Max. Karena itu, jangan unggah dalam bentuk paket terlebih dahulu. Periksa apakah penyebab 2, 5, atau 6 yang menimbulkan masalah ini.
b) Jika material ditampilkan dengan normal seperti contoh di bawah, Anda dapat mengemas dan mengunggah teksturnya bersama model.
c) Operasi Archive adalah sebagai berikut:
Archive: Fungsi pengemasan ini mengatur file tekstur dan file lainnya ke dalam satu file terkompresi, sehingga file dapat dibuka di komputer lain dengan 3ds Max tanpa kehilangan tekstur.
d) Setelah dikemas, unggahan akan ditampilkan dengan normal.
Cara memeriksa: setel ulang jendela Material Editor, lalu buka Resource Tracking dengan Shift+t.
Menyetel ulang Material Editor mencegah faktor material yang tidak diperlukan memengaruhi tampilan Resource Tracking.
Anda dapat memeriksa status di bagian belakang. Jika ada file yang hilang, statusnya akan ditandai.
Jika tekstur hilang, tetapkan ulang tekstur (sesuai untuk tekstur yang hilang atau nama tekstur yang berubah).
Langkah untuk menetapkan ulang tekstur:
Buka Material Editor→(Material Sampling) Eyedropper→ambil sampel bagian model yang perlu diatur teksturnya→klik Diffuse Texture→Bitmap→temukan tekstur yang diperlukan→Confirm.
Jika hanya jalur tekstur yang berubah, Anda dapat menyesuaikan pengaturan di Resource Tracking.
Langkah untuk mengubah jalur tekstur:
Buka Resource Tracking dengan Shift+t→Path→Highlight Editable Resources→Path→Set Path (sebaiknya tempatkan tekstur dalam satu map)
Setelah jalur diatur, status tekstur akan menampilkan Found.
Setelah itu, lanjutkan proses pengemasan dan unggah kembali.
Jika tidak ada masalah pada model dan tekstur, periksa pengaturan render.
Buka Render Settings→V-RAY→Global Switches→Override mtl. Jika opsi ini dicentang, hapus centangnya.
Dalam situasi ini, pratinjau model di 3ds Max terlihat normal.
Untuk pengaturan diffuse, periksa apakah bola material menampilkan material. Klik dua kali bola tersebut untuk melihat pratinjau.
Ini mirip dengan menyesuaikan opacity di Photoshop dan jarang perlu diubah.
Untuk masalah normal, gunakan contoh sebuah kotak. Pada dua balok dengan bahan yang sama, salah satu balok diberi normal.
Setelah diunggah, hasilnya menjadi seperti ini.
Solusi:
Pilih model→klik "Modifier"→cari "Normals"→centang "Flip Normals"
Ubah menjadi editable mesh, lalu selesai.
Jika sebagian atau semua bahan muncul sebagai blok berwarna mencolok atau sepenuhnya hitam pada pratinjau unggahan, penyebabnya mungkin adalah multi-sub materials di 3Dmax.
Buka material editor pada file 3Dmax asli, gunakan eyedropper untuk memilih bagian yang tidak normal, lalu periksa jenis bahannya.
Jika jenisnya "multi-sub/object", Anda perlu memisahkan multi-sub materials sebelum mengunggah.
Setelah dipisahkan, pastikan semua bahan ditetapkan dalam bentuk tekstur VRayMtl. Jika tidak, hasil unggahan masih dapat terlihat hitam atau tampilannya kurang baik.
