Greptile Summary

Adds a new RendererConfigStore module that allows users to select renderer backends via Hydra config groups (e.g., render=isaac_rtx or render=newton_warp). The selected renderer config is automatically applied to all cameras in the environment. The implementation properly handles the optional isaaclab_newton dependency with try-except imports and conditional registration.

Key changes:

• New render_config_store.py module registers renderer presets in Hydra ConfigStore
• hydra.py adds default render config (isaac_rtx) and extracts process_hydra_config() to eliminate code duplication between production and test code
• Tests validate default behavior, explicit overrides, and error handling for invalid configs
• Newton-specific test properly uses @pytest.mark.skipif decorator

Previous review comments addressed:

• Optional Newton imports now wrapped in try-except
• Conditional registration checks if NewtonWarpRendererCfg is available before registering
• Test for newton_warp properly skipped when dependency unavailable

No issues found.

Confidence Score: 5/5

• This PR is safe to merge with no identified risks
• Clean implementation with proper error handling for optional dependencies, comprehensive test coverage including edge cases, successful code deduplication, and all previous review concerns properly addressed
• No files require special attention

Important Files Changed

Filename	Overview
source/isaaclab_tasks/isaaclab_tasks/utils/render_config_store.py	New module that registers renderer config presets for Hydra; properly handles optional Newton imports with try-except and conditional registration
source/isaaclab_tasks/isaaclab_tasks/utils/hydra.py	Adds render config support with defaults, extracts shared process_hydra_config function to eliminate duplication; applies renderer config recursively to all camera objects
source/isaaclab_tasks/test/test_hydra.py	Refactored to reuse process_hydra_config, adds comprehensive tests for render config defaults, overrides, and newton_warp (properly skipped when unavailable)

Thanks @bareya for the PR! Could you add the changes from Greptile, it would make sense to skip the test if newton is not there.
