HDRI

HDRI maps are a powerful way to light scenes and add realistic reflections. Every project in Vectary comes with a default HDRI environment that provides basic lighting by default. You can choose from a range of HDRI maps available in the built-in library via the Environment settings, or import a custom HDRI file. However, keep in mind that HDRI maps can dramatically increase project size — especially when imported in high resolution.

Tips & recommendations

• Check file size before importing – HDRI files, particularly custom ones, can be very large. Always verify the file size and consider optimizing before upload.

• Reduce resolution if possible – HDRI resolution has a direct impact on its file size. If your scene doesn’t rely on fine background detail, consider using a lower resolution HDRI to reduce load times. HDRI resolution can be adjusted directly in Studio — in the Environment settings.

• Use compression – When exporting or preparing HDRI files, consider using DWAA or DWAB compression. These methods can significantly reduce file size without major visual loss.
