Pesan kesalahan “OBJ file should not exceed 100MB” berarti ukuran model terlalu besar setelah objek diekspor. Selain objek, model yang diekspor masih memiliki atribut material.
Karena atribut material tidak dapat diubah, opsi pertama adalah mengubah atribut model, yaitu menyesuaikan jumlah poly model. Saat ini, platform Coohom mendukung maksimal 80w poly. Namun, beberapa klien memberikan umpan balik bahwa model dengan 79w poly juga gagal diunggah. Hal ini mungkin disebabkan oleh atribut material. Dalam kondisi ini, Anda dapat mengoptimalkan jumlah poly atau mengompres file sebelum mengunggahnya.
1. Gunakan fungsi Optimize (3ds Max 2012 atau versi lebih baru).
Tekan Ctrl + A untuk memilih model, lalu klik kanan dan pilih Convert to Editable Mesh.
Tekan 7 untuk memeriksa jumlah poly model. Dalam contoh ini, 200w+ sudah melebihi batas 80w, sehingga jumlah poly perlu dikurangi.
Pertama, cari area dengan poly yang lebih padat. Jika Anda mengurangi poly di area yang jumlah poly-nya lebih sedikit, model dapat mengalami masalah yang tidak diharapkan.
Tekan F3 untuk menampilkan wireframe. Klik Detach untuk memisahkan sebagian poly yang padat dari model.
Klik Optimize di Modifier List.
Jumlah poly sudah berkurang, tetapi masih melebihi 80w. Selanjutnya, Anda dapat: 1. mengubah Face Thresh; 2. memilih lokasi lain dengan wireframe yang padat untuk dioptimalkan.
Konversi ke Editable Mesh setelah mengurangi poly
Mengurangi terlalu banyak poly dapat merusak model. Selama masih dalam batas, jumlah poly yang lebih banyak akan menghasilkan efek model yang lebih baik.
Jika Anda sudah mengatur UV mapping sebelum mengurangi poly, ingat untuk mengatur ulang UV mapping tersebut.
2. Gunakan ProOptimizer (hanya mendukung 3ds Max 2016 atau versi lebih baru).
Pilih lokasi yang ingin Anda ubah, lalu klik ProOptimizer di Modifier List.
Klik Calculate.
Setelah perhitungan selesai, klik Vertex % untuk mengoptimalkan model. Perbandingan sebelum dan sesudah optimasi akan terlihat di sisi kiri. Jika model memiliki tekstur, Anda dapat mengeklik Keep Textures.
Sekarang jumlah poly sudah di bawah 80w. Model siap diunggah.
Klik Customize > Files > Compress on Save.
Archive file Anda.
Terakhir, unggah model Anda ke platform Coohom.
