Adrian Vallecilla’s 5-hour workshop details a complete workflow for integrating hero assets into backplates with photorealistic results. Using a classic technique in visual effects production, Adrien reveals how to transform a 3D scan of a train into a production-ready asset using Maya, discussing the important hard-surface modeling theories while demonstrating the process. The texturing portion includes how to clean up textures from the 3D scan and project them back onto a clean 3D asset using Mari — a standard practice that ensures the CG asset is usable in VFX production.


Back in Maya, the look-dev, lighting, and rendering is handled with V-Ray. Adrien discusses the importance of matching the lighting of the plate with the 3D asset being integrated for truly realistic results and demonstrates how to recreate the correct lighting scenario. Using Maya's render setup tools, Adrien shows how to export all the necessary lighting passes required for professional compositing in Nuke. As well as detailing the process, he also discusses what to look out for when creating realistic CG integrations using Nuke.


Provided with this workshop is Adrien’s low-res model of the environment and camera (.mb file for Maya) used for the shot, which you can download and use with your own assets. An HDR image and backplate courtesy of HDRI Haven is also included from their free collection.

01IntroductionFree

Adrien introduces his workshop, which addresses the realities of VFX production: most assets begin as 3D scans that require extensive cleanup and optimization. His comprehensive workflow, from scan cleanup through to final integration, equips anyone looking to work in visual effects studios, as this type of work accounts for the majority of modeling and texturing tasks in professional VFX pipelines. Adrien's combination of technical modeling skills, texturing techniques, and integration knowledge makes this a valuable learning experience for industry preparation.

Duration: 7m 4s

Introduction
02Modeling — Part 1Free

This lesson showcases how successful hard-surface modeling requires both technical precision and strategic planning. Adrien demonstrates that mastering traditional polygon modeling techniques in Maya, particularly proper quad topology, edge-flow management, and UV-friendly construction, is more valuable for industry work than relying solely on sculpting tools. The key to professional-quality results lies in understanding how topology affects smoothing, creating clean geometry that serves both visual and technical requirements for production pipelines.

Duration: 49m 52s

Modeling — Part 1
03Modeling — Part 2

This lesson provides essential knowledge for transitioning from student work to professional production standards. Adrien discusses why understanding these cleanup and optimization processes sets professional artists apart from beginners, demonstrating respect for downstream departments and ensuring assets can be used efficiently throughout the production pipeline. These technical skills are crucial for maintaining quality standards and avoiding costly asset revisions in team-based environments.

04Texturing — Part 1

Adrien's texture transfer workflow provides an efficient way to combine the realism of scanned textures with the clean topology and UVs of properly modeled assets. While the initial transfer captures much of the detail automatically, the technique's success relies heavily on thorough cleanup and enhancement work. Adrien's emphasis on maintaining fast workflows and understanding texture fundamentals, rather than relying on real-time material feedback, demonstrates a production-focused approach to texturing that prioritizes efficiency and final output quality.

05Texturing — Part 2

This lesson demonstrates a professional texturing workflow that balances artistic quality with production efficiency. Adrien successfully transforms problematic scan data into clean, detailed textures by combining manual cleanup work with procedural techniques. His emphasis on working smart by prioritizing visible areas while maintaining technical consistency demonstrates mature production experience that maximizes quality within time constraints.

06Look Development

This lesson demonstrates a professional and methodical approach to look development that prioritizes efficiency and organization. Adrien's systematic workflow of tackling bump, specular, and diffuse values in sequence, combined with proper AOV usage and utility node setup, creates a foundation for high-quality material development. His emphasis on working fast while maintaining quality, using simple Fresnel values, and organizing materials for easy debugging, reflects real-world production practices that can significantly improve both workflow speed and final results.

07Lighting — Part 1

This lesson demonstrates a methodical approach to lighting for VFX integration that prioritizes technical accuracy before artistic refinement. Adrien emphasizes the importance of neutralizing all input imagery and establishing proper light-to-shadow relationships using gray materials before moving to final look development. His workflow prepares multiple render passes and light selections that will provide maximum flexibility during the compositing phase in Nuke, where final adjustments and integration will be completed.

08Lighting — Part 2

This lesson discusses how modern render engines like V-Ray are designed to handle most sampling decisions automatically, requiring artists to focus more on scene optimization and proper asset management rather than manual sampling controls. Adrien's render layer workflow demonstrates a streamlined approach to generating the multiple passes needed for professional compositing, while the render settings guidance emphasizes that proper scene optimization is more important than tweaking sampling parameters.

09Compositing in Nuke

Adrien concludes with a lesson on successful compositing that relies heavily on thorough preparation in all preceding pipeline stages. Rushing any step creates cascading problems that become harder to fix later. The key to professional VFX work is following established workflows methodically, working efficiently, and maintaining objectivity through techniques like reference matching and taking breaks to refresh visual perception. This systematic approach, combined with consistent practice, forms the foundation for working effectively in a professional VFX environment.
