Common Torque 3D Issues and Solutions

1. Engine Crashes on Startup

Torque 3D fails to launch or crashes on initialization.

Root Causes:

  • Missing or corrupted engine files.
  • Unsupported GPU or outdated graphics drivers.
  • Incorrect engine configuration.

Solution:

Ensure that all necessary engine files are present:

git clone https://github.com/GarageGames/Torque3D.git

Update GPU drivers:

NVIDIA: sudo apt update && sudo apt install nvidia-driver-latest
AMD: sudo apt update && sudo apt install amdgpu-pro

Reset Torque 3D settings by deleting game/config.cs:

rm -rf game/config.cs

2. Shader Compilation Failures

Custom shaders or built-in shaders fail to compile, causing rendering issues.

Root Causes:

  • Syntax errors in shader code.
  • Unsupported GPU shader model.
  • Missing shader dependencies.

Solution:

Check shader compilation logs for errors:

torque3d/logs/shader_errors.log

Ensure shaders use a supported version:

#pragma version 330

Manually recompile shaders:

./Torque3D.exe -compileShaders

3. Poor Performance and FPS Drops

Torque 3D runs slowly, with frequent frame drops.

Root Causes:

  • High-resolution assets consuming excessive memory.
  • Unoptimized physics calculations.
  • Excessive draw calls in the scene.

Solution:

Lower texture resolution:

$Pref::Video::TextureQuality = "Low";

Optimize physics by adjusting tick rates:

$pref::Physics::tickRate = 30;

Reduce draw calls using batch rendering:

object.mergeMeshes();

4. Scripting Errors in TorqueScript

Custom scripts fail to execute or cause runtime errors.

Root Causes:

  • Syntax errors in TorqueScript files.
  • Incorrect function calls.
  • Undefined variables or missing objects.

Solution:

Enable debug mode in TorqueScript:

debugEcho("Script Debugging Enabled");

Check the TorqueScript console for error messages:

openConsole();

Ensure variables are correctly initialized:

%player = new Player();

5. Asset Import Issues

Models, textures, or animations do not appear correctly in Torque 3D.

Root Causes:

  • Incorrect file formats.
  • Missing materials or textures.
  • Improper scaling or pivot misalignment.

Solution:

Convert assets to supported formats:

Blender -> Export as COLLADA (.dae)

Ensure materials are properly assigned:

object.setMaterial("myMaterial");

Adjust scaling in TorqueScript:

object.setScale("1 1 1");

Best Practices for Torque 3D Optimization

  • Use LOD (Level of Detail) models to reduce rendering overhead.
  • Optimize physics by limiting real-time collision checks.
  • Utilize batching and instancing to minimize draw calls.
  • Regularly clean logs and cache files to prevent memory leaks.
  • Profile game performance using Torque 3D’s built-in profiler.

Conclusion

By troubleshooting engine crashes, shader failures, performance bottlenecks, scripting errors, and asset import issues, developers can effectively utilize Torque 3D for game development. Implementing best practices ensures a stable and efficient gaming experience.
