Greptile Summary

This PR replaces the hardcoded read_gpu_transforms=False in RendererConfig with a runtime version check: GPU transforms are enabled only when the installed ovrtx version is greater than 0.2.0, working around a known bug in earlier releases. The change is minimal and isolated to the renderer initialisation path.

Confidence Score: 4/5

Safe to merge; the change is a small, well-scoped version guard with only minor P2 concerns.

Only P2 findings: a possible off-by-one on the version boundary (> vs >=) and the absence of a try/except around the module-level version parse. Neither is a runtime blocker under normal conditions, but both could surprise future maintainers or users on edge-case ovrtx builds.

source/isaaclab_ov/isaaclab_ov/renderers/ovrtx_renderer.py – verify the exact ovrtx release that fixed the GPU-transform bug to confirm the > boundary.

Important Files Changed

Filename	Overview
source/isaaclab_ov/isaaclab_ov/renderers/ovrtx_renderer.py	Adds a module-level packaging.version check against ovrtx.__version__ to enable read_gpu_transforms=True for versions > 0.2.0; minor concerns around the version boundary and import-time error handling.

Version boundary may be off-by-one

The comment states the bug existed in "previous versions," but the threshold > Version("0.2.0") treats 0.2.0 itself as a buggy version (leaves read_gpu_transforms=False). If the GPU-transform fix was introduced in 0.2.0 (rather than strictly after it), the condition should be >= Version("0.2.0"). Worth confirming the exact release that introduced the fix.

No guard against malformed or missing __version__

Version(ovrtx.__version__) is evaluated at module-import time. If ovrtx doesn't expose __version__ (AttributeError) or its value isn't a valid PEP 440 string (packaging.version.InvalidVersion), the entire module fails to import. Consider wrapping this in a try/except so a version-parsing failure degrades gracefully (e.g. falls back to False):

try:
    _OVRTX_READ_GPU_TRANSFORMS = Version(ovrtx.__version__) > Version("0.2.0")
except Exception:
    _OVRTX_READ_GPU_TRANSFORMS = False
