I'm trying to debug a rendering issue which I think may be related to DDS textures. Does anybody have a link for a map and/or mod that they are sure absolutely, 100% does not use or reference any DDS textures (ie, a map that uses PNG, BMP, TIFF or JPEG instead)?
I know I could create a map as an alternative but I thought I'd ask first.
when mapconv builds the map it creates a bunch of dds files that it think puts into the smt.. I am not sure if smt is a container for dds textures or what. Probably behe would be a better person to ask.

It is, the SMF format stores all (32x32-sized) texture tiles as DXT1-compressed data.
(actually, the type of compression used is up to the compiler and not supposed to be limited to just DXT1, but all current map loading/drawing code expects it)
If I understand Kloot correctly the map compiler will create DDS regardless of the inputs. I'm still wondering if it's possible to have a "null" map or texture so I can rule out any DDS being in the pipeline.
If not I'll probably hack my local Spring to replace DDS with a default uncompressed texture at runtime. I'm almost positive the issues I'm seeing are DDS/DXT related. For example the Spring start screen and glText elements render fine, even over the corrupt textures. I'm just looking for proof this is about S3TC and not shaders or memory exhaustion.
