banding issues

[bzhyoyo]

Hi all,
I'm currently working on the skin for the SE5 I modelled.
SE5a WIP - Military-Meshes.com

I'm following Blowhard's awesome tutorial "fabric the hard way" and I have a problem with the rib shadows : I use a gradient to paint the shadow.
When I flatten the image and save to DXT1 (dds) format, this is the result I get. Any ideas to avoid the issue? Cheers!

I'm not really familiar with DDS, but if it generates 256 colors I'd do this:
I'd try to save it as BMP with Bright first.
And then convert the BMP to DDS.

We have Bright here as PS plugin and as seperate program a tutorial on how to use the program has just been uploaded this week.

All of the DXT formats do some compression, which will probaby lead to such banding. Using DXT3 is particularly known for adding banding artifacts to textures, though it can also hold alpha layers.

Thanks for the tip with bright Serval, I may try it later but I reworked the shadows and I discovered that converting my ps file into a bmp before converting it to dds created more artifacts than flatening my ps file and saving it directly as a dds.

if this doesn't help add some slightly noise to your basic colors.
