The SGI™ Image File format is a bitmap file type created by Silicon Graphics ® . SGI Image File support in 3ds Max lets you load and save files in both 8- and 16-bit color depth, with alpha channels, and RLE Compression.
SGI Image Files can have these filename extensions: SGI, RGB, RGBA, INT, INTA, or BW.
Interface
Clicking Render or Setup in the Render Output File dialog displays the RGB Image File Format dialog.
Channel Bit Depth group
- 8 Bit Saves the SGI Image File as 8-bit color.
- 16 Bit (The default.) Saves the SGI Image File as 16-bit color.
- Use Alpha
- When on, saves Alpha channels with the SGI Image File. Default=on.
- Compressed
- When on, saves the SGI Image File with RLE compression. Default=on. Note: In some cases, the RLE algorithm can cause a “compressed” file to be larger than an uncompressed file.
