Greptile Summary

The PR enables synchronous texture streaming in OVRTX to improve cross-run rendering determinism and documents the new ovrtx 0.4.1 requirement.

• Imports TextureStreamingMode and configures RendererConfig to use synchronous streaming.
• Updates installation guidance and adds a changelog fragment.
• The repository dependency constraints were not raised to the newly required minimum version.

Confidence Score: 4/5

The PR should not merge until the ovrtx dependency constraints are raised to 0.4.1 so supported installation paths cannot produce an incompatible renderer environment.

The renderer unconditionally imports and uses an API documented as requiring ovrtx 0.4.1, while repository extras and CI installation metadata continue to allow ovrtx 0.4.0.

Important Files Changed

Filename	Overview
source/isaaclab_ov/isaaclab_ov/renderers/ovrtx_renderer.py	Enables synchronous texture streaming but uses a 0.4.1-only API while supported dependency metadata still permits ovrtx 0.4.0.
source/isaaclab_ov/changelog.d/enable-synchronous-texture-streaming.rst	Accurately documents the renderer change and its ovrtx 0.4.1 minimum-version requirement.

Dependency permits incompatible OVRTX API

When a supported installation path resolves ovrtx==0.4.0, this unconditional TextureStreamingMode import uses an API that requires 0.4.1, causing the OVRTX renderer module to fail to import. Raise the lower bound in the repository's ov and ovrtx dependency constraints so installations cannot select the incompatible release.

Isaac Lab Review Bot

The change enables synchronous texture streaming at the sole OVRTX RendererConfig construction site and records the new ovrtx 0.4.1 requirement. The proposed packaging finding is not supported because the supplied context does not show the repository’s current ovrtx dependency constraint or establish that the ovrtx extra can resolve 0.4.0.

• Design and architecture: Applying the deterministic streaming mode when constructing OVRTXRenderer keeps the policy centralized and leaves the ovstage and legacy rendering paths unchanged.
• API: No Isaac Lab public symbols, signatures, or return types change. The compatibility surface reviewed was the new use of TextureStreamingMode, the stated ovrtx 0.4.1 minimum, and the installation guidance emitted when ovrtx is absent.
• Implementation: TextureStreamingMode.SYNCHRONOUS is passed unconditionally to the existing renderer configuration, and the guarded import remains correct for a missing ovrtx package. A missing symbol on an older installed wheel would raise ImportError, but the patch does not include enough dependency metadata context to demonstrate that such a wheel remains permitted by the project’s declared constraints.

No blocking issues. No inline issue met the actionable-evidence threshold; the assessment above records the review feedback.
