PERANCANGAN TEKSTUR PHYSICAL BASED RENDER BERBASIS IMAGE PAINTING PADA FILM ANIMASI “NIRMALA” MENGENAI RESTORASI ALAM

Perancangan tekstur pada aset lingkungan film animasi memerlukan metode yang mampu menghasilkan visual realistis dengan proses produksi yang efisien. Penelitian ini bertujuan merancang tekstur Physical Based Rendering (PBR) berbasis Image Painting pada aset lingkungan film animasi Nirmala mengenai restorasi alam. Metode penelitian yang digunakan adalah Design and Development (D&D) menurut Richey dan Klein (2007), yang meliputi tahap analisis, perancangan, pengembangan, dan evaluasi. Proses pembuatan tekstur dilakukan melalui workflow PBR dengan menghasilkan texture map berupa Base Color, Roughness, Normal, Ambient Occlusion, dan Emissive menggunakan teknik Image Painting. Hasil penelitian menunjukkan bahwa metode yang diterapkan mampu menghasilkan tekstur yang realistis dan sesuai dengan konsep visual film. Pengujian juga menunjukkan bahwa model low poly memiliki ukuran file 79 MB dengan waktu render 10 detik, sedangkan model high poly berukuran 103 MB dengan waktu render 20 detik menggunakan Iray. Hasil tersebut menunjukkan bahwa penerapan tekstur PBR berbasis Image Painting pada model low poly mampu mempertahankan kualitas visual sekaligus meningkatkan efisiensi ukuran file dan waktu rendering, sehingga sesuai diterapkan pada proses produksi animasi 3D

Creating textures for environmental assets in animated films requires a method that produces realistic visuals while maintaining production efficiency. This study aims to design Physical Based Rendering (PBR) textures using the Image Painting technique for environmental assets in the animated film Nirmala, which focuses on environmental restoration. The research employed the Design and Development (D&D) method proposed by Richey and Klein (2007), consisting of the stages of analysis, design, development, and evaluation. The texturing process followed the PBR workflow by producing Base Color, Roughness, Normal, Ambient Occlusion, and Emissive maps using Image Painting techniques. The results indicate that the proposed method successfully produces realistic textures that align with the film's visual concept. Performance testing also shows that the low-poly model has a file size of 79 MB with a rendering time of 10 seconds, while the high-poly model has a file size of 103 MB with a rendering time of 20 seconds using the Iray renderer. These findings demonstrate that applying PBR textures based on Image Painting to low-poly models can maintain visual quality while improving file size efficiency and rendering performance, making the method suitable for 3D animation production workflows
