How to select between JPG vs EXR texture file types

Poly allows the exporting of HD textures with PBR maps in two formats: 8-bit JPG and 32-bit EXR (only available with Poly Infinity ∞).

8-bit JPG

JPG file is a compressed format that can only store 8 bit per channel. It stores RGB values (3 channels) and it uses lossy compression.

As such, your exported textures and PBR maps in 8-bit JPG might be inconsistent and tend to be lower in quality when imported into various 3D tools like Blender, Unity, etc.

However, it takes significant less disk space and it tends to be enough in quality for background textures and for personal or educational use.

32-bit EXR

EXR format writes 32 bit float values for each channel, stores RGBA (4 channels), and it uses lossless compression.

While a bit larger in file size, your exported textures and PBR maps in 32-bit EXR will have significantly higher quality when imported into your 3D tools. It’s a default format for all high-quality 3D projects and commercial projects.

Please note that working with EXR format has a higher hardware requirement.
