Character, face, and speech animation rendered in detailed environments with Flexible Rapid (FlexRap) production

FlexRap is a flexible and rapid real-time-based animation production and rendering workflow/pipeline to characterize (create character controls) for various types of skeleton/bone structures, such as Maya, Motion Builder, Mixamo, Unreal, Cinema 4D,… characters, animate and render them in detailed environments using keyframed and nonlinear animation.
It allows rigging/creating skeletons skin weights and character controls for 3D character models; and allows retargeting animation among various characters.
The workflow is non-destructive, allowing modifying models, accessories, character subdivisions, or blend shapes during the animation, or rendering process.
The blend shapes are decoupled from the character, and they can be changed/re-applied non-destructively even after the animation completion to conform to the new shapes.
Human characters have generated blend shapes for rapid speech and facial animation setup. Characters with alien, non-human facial features may require blend shape creation for speech animation.
The characters can have non-destructive layered textures, dynamic wrinkles, and changeable face painting, where dynamic wrinkles deform the face and face painting upon muscle movement and speech.
Characters can have asymmetrical facial muscle suppression under the facial metal plate for cyber-styled characters.

It allows for creating character interaction with the use of various constraints and allows for creating hair and clothing simulations.
In most cases, the characters are pushed through various stages of the pipeline in FBX format with auto texture assignments throughout the modeling, texturing, animation, and rendering stages.
It allows relatively quick creation of environments, their texture, and transfer materials to integrate characters with rich and detailed environments using USD file format for real-time or near real-time rendering for storytelling.
The new pipeline carries over and improves upon the best features of legacy animation applications, such as 3ds Max CAT Footprint, Softimage FaceRobot Lip Sync, viseme, or Speech Clip, Softimage Species, Maya Human IK rigging, MotionBuilder Characterization or Auxiliary pivot system, Mixamo style auto skinning with correct fingers, MotionBuilder like non-linear animation system, simplified constraint system, an improved version of Maya-ZBrush’s blend shape system in a non-destructive workflow.
ZBrush GoZ style Live Link interaction between multiple applications such as Maya, Cinema 4D, Character Creator, iClone, Unreal Engine Editor, Unity, Blender, Substance Painter, and ZBrush to transfer and auto setup blend shapes, textures, and shaders, or create UVs. This is significant because a scene can have over a hundred textures files and many blend shapes to transfer and set up through the pipeline.

Sci-Fi Short Film Teaser - FlexRap 4K Workflow Showcase

This teaser introduces my upcoming two-stage sci-fi project—a 3D-rendered comic and short animated film—produced using my proprietary FlexRap (Flexible Rapid) pipeline. This workflow enables cinematic-quality, near real-time production, designed for visual fidelity and performance across modeling, shading, dynamics, and animation.
This production showcases full directorial control over every visual element:

🎬 Character Creation
• Custom-designed character topology, facial structure, blend shapes
• Precision-timed visemes and speech animation
• Full body + hand/finger animation
• Realistic hair and skin shading

👕 Clothing & Dynamics
• High-resolution clothing design
• Simulation-ready topology
• Cached cloth dynamics using FlexRap techniques

🌌 Cinematic Environments
• Detailed, expansive environments with consistent geometry across shots
• Controlled fog usage—not a visual shortcut—allowing full-depth visibility
• Rendered in 4K averaging 5–6 seconds per frame with NVIDIA DLAA (Deep Learning Anti-Aliasing) for clarity, depth, and minimal flicker

🛠️ Rendering Workflow
• FlexRap enables consistent lighting, camera depth, and scene integrity
• Near real-time rendering—optimized for production-ready results while maintaining high-end anti-aliasing and lighting fidelity

This video is part of a crowdfunding campaign hosted on Crowdfundr, where supporters can help bring this sci-fi universe to life—starting with a photo-realistic comic book and expanding into a cinematic short film.

Thanks to FlexRap’s versatile rendering workflow, the sunlight source can be decoupled, allowing more sophisticated and detailed lighting to be integrated with the character, as demonstrated in the first three images. The advantage is Light Linking while rendering under 10 seconds. The following two female headshots were rendered using Maya and 3ds Max. Their rendering times were significantly higher:
