HDR does not support alpha transparency. Transparent DDS areas must be flattened onto a background color.
Animated, sequence, or multipage inputs need explicit frame/page handling.
Converting DDS to HDR decodes the source image and writes a HDR output. Use this route when HDR is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on HDR compression: rle_depends.
Choose conversion targets based on HDR compression, transparency, animation, metadata, and compatibility requirements.
Known metadata support: texture headers, mipmaps, cube maps, arrays.
