Troubleshooting Resource Serialization and Export Issues in ShiVa3D Projects

Details: Category: Game Development Tools; By Mindful Chase; 26.Jul; Hits: 5

ShiVa3D is a versatile game engine used for building cross-platform 3D applications, especially popular in mobile and embedded game development. While its graphical editor and Lua scripting capabilities make it accessible, many developers hit critical roadblocks during large-scale project integration. A particularly tricky problem is "inconsistent asset behavior due to improper resource serialization and platform-specific export issues." These bugs often manifest only after deployment on certain devices or platforms, making them difficult to trace during development. Diagnosing and resolving these serialization mismatches is crucial for studios aiming to deliver polished, platform-consistent experiences.

Understanding the Problem

What is Resource Serialization in ShiVa3D?

ShiVa3D uses a proprietary format to serialize scenes, materials, AI models, and textures. During export, these resources are transformed into platform-specific formats optimized for performance. However, serialization is highly sensitive to changes in resource references, dependency resolution order, and export settings. A single missing flag or version mismatch can result in invisible assets, logic failures, or broken shaders at runtime.

Symptoms of Serialization Failure

Assets (models, textures, AI) work in editor but not in exported builds
Inconsistent behavior across iOS, Android, and Windows
Crash logs indicating missing resource handles or corrupted buffers

Architectural Implications

Asset Pipeline Complexity

ShiVa3D projects rely on a centralized resource system. Improper management of UUIDs, stale cache files, or duplicate resource names can cause internal mapping failures during serialization. Teams often overlook this complexity in rapid prototyping workflows.

Platform Abstraction Layer

Each target platform interprets compiled ShiVa packages slightly differently. Android and iOS have stricter memory and file path constraints, which amplify any serialization issues originating from PC-based exports.

Diagnostics

Step-by-Step Debugging

Use the ShiVa Authoring Tool's verbose export logs. Enable Debug Resource Warnings in the export profile.
Cross-check exported resource paths in the .STK archive using external tools or file inspectors.
Test assets in the standalone ShiVa Player before full deployment to isolate runtime issues.
Use logging functions in Lua (e.g., log.message()) to verify if resources are loading as expected.

if ( application.getCurrentUserLocale ( ) == "fr" ) then
    log.message ( "Loaded French assets." )
else
    log.message ( "Loaded default assets." )
end

Common Pitfalls

Referencing Unsaved or Temporary Assets

Developers sometimes test with assets not properly saved or committed to the resource tree. These assets are not serialized, leading to null references in runtime builds.

Incorrect Use of AI Model References

Copy-pasting AI models between projects without re-registering UUIDs creates mismatches during serialization, causing events or state logic to silently fail.

Version Drift Between Editor and Exporter

If the ShiVa Editor and Authoring Tool are not aligned in version, resource packing may differ, resulting in corrupt or unreadable exports.

Fix Strategy

Standardize Asset Workflows

Use consistent naming conventions and resource hierarchies.
Commit all assets before exporting builds.
Run pre-export validation scripts to check for unresolved references.

Validate Export Profiles

Ensure that the correct compression, resolution, and platform flags are set in export profiles. Use separate profiles for each target platform to avoid collisions.

Rebuild Resource Trees

When corruption is suspected, delete intermediate export files and regenerate the resource tree using the Rebuild Resources option from the ShiVa Editor.

Best Practices

Keep the ShiVa Editor and Authoring Tool on the same version at all times.
Test exports on emulators and real devices for each target platform.
Use logging aggressively in AI Models to detect runtime failures.
Archive and version resource trees before major updates.
Automate asset validation using Lua scripts during build staging.

Conclusion

ShiVa3D's resource serialization issues can derail even well-planned game development projects, especially when building for multiple platforms. These problems require a disciplined workflow, robust validation practices, and a strong understanding of the engine's internal packaging system. By isolating serialization points, leveraging built-in logging, and standardizing export procedures, developers can avoid runtime surprises and ship consistent, high-quality games across platforms.

FAQs

1. Why do assets work in the editor but not in the build?

This usually indicates they were not serialized during export—either because they were unsaved, temporary, or excluded by the export profile settings.

2. How can I debug asset loading at runtime?

Use Lua functions like log.message() and conditional checks to verify asset availability. You can also simulate the runtime environment using the ShiVa Player.

3. What causes AI model failures in exported builds?

Common causes include UUID mismatches, missing event registrations, or serialization order errors during asset copy/paste operations.

4. Is it safe to use the same export profile across platforms?

No. Each platform has specific constraints (e.g., resolution limits, path lengths). Create dedicated export profiles for Android, iOS, Windows, etc.

5. Can I automate resource validation in ShiVa3D?

Yes. Use Lua scripts to check for null handles, missing references, or asset inconsistencies as part of a pre-deployment QA process.
