exr

What problem does it solve?

This Skill simplifies complex tasks involving OpenEXR files, a standard in VFX for handling high dynamic range images and render passes, making them accessible for inspection, manipulation, and conversion.

Core Features & Use Cases

• Channel Inspection: Easily view all channels within an EXR file, including render passes and metadata.
• Beauty/RGB Extraction: Extract and convert beauty passes to standard image formats like PNG, with support for color space transformations (e.g., ACEScg to sRGB).
• Cryptomatte Decoding: Visualize and extract material, object, or asset IDs from Cryptomatte passes as colored segmentation masks.
• Arbitrary Channel Extraction: Pull out specific channels like depth or normals and save them as grayscale or RGB images.
• Batch Processing: Apply operations to entire directories of EXR files efficiently.
• Use Case: A compositor needs to quickly isolate specific objects or materials from a render for effects work. They can use this Skill to generate clean masks from the EXR's Cryptomatte data.

Quick Start

Use the exr skill to extract the beauty pass from the file 'render.exr' and convert it to sRGB.
