Good use cases
- Store three grayscale maps in R, G and B. Optionally add a fourth map as the alpha channel and export the result in several image formats.
- Common ORM/ARM mapping: R = Occlusion, G = Roughness, B = Metallic. Each source is read as grayscale.
Tips and limitations
Which inputs are supported?PNG, JPG, JPEG, WebP, AVIF, BMP, TIFF, HEIC, HEIF
- Without a custom size, the first loaded map is used. Different source sizes are scaled to fit.
- JPEG cannot store an alpha channel; transparency is flattened onto the selected background colour.
