Summary

RenderVar prims whose sourceName starts with “semantic” must use BLOSC compression.

Examples

# Invalid: semantic RenderVar without BLOSC compression
def RenderVar "SemanticVar"
{
    token sourceName = "semanticSegmentation"
    token dataType = "uint"
    # No compression attributes — defaults to uncompressed
}

# Invalid: semantic RenderVar with a non-BLOSC compression format
def RenderVar "SemanticVar"
{
    token sourceName = "semanticSegmentation"
    token dataType = "uint"
    uniform token srtx:compression:type = "hevc"
}

# Valid: semantic RenderVar with BLOSC compression
def RenderVar "SemanticVar"
{
    token sourceName = "semanticSegmentation"
    token dataType = "uint"
    uniform token srtx:compression:type = "blosc" (
        allowedTokens = ["hevc", "h264", "av1", "blosc"]
    )
}

How to comply

• For any RenderVar whose sourceName begins with "semantic", set srtx:compression:type = "blosc".

• Non-semantic RenderVar prims (e.g. "LdrColor", "DepthLinearized") are not affected by this requirement.
