I'm also having the problem of textures not being found. I've been reading and messing with this for a week before bothering the community, but I'm stumped.
I have what I believe to be the correct file structure, the materials file looks correct, but whether I use TGA or DDS images, I have either a black brush or a blue 'no shader', respectively. The only thing visible is `oh_ed.jpg' in DarkRadiant.
My images are being processed through Gimp. I am using mipmaps, I've tried dxt1 and dxt3, no RLE, origin is bottom left, they are to the power of 2, etc.
The normalmap is visible if I use the DDS (but there's no diffuse image), and if I uncomment the DDS in order to force TGA, then the brush shows up flat-black in the game and DR's full-light view.
There is always a warning or two about missing images no matter what I try when I run dmap, eg: WARNING:Couldn't load image: textures/darkmod/map_specific/oh/oh
On a sidenote: When it's said to put a copy of the textures in the main Darkmod folder, I've tried putting the textures in as a PK4. 'tdm_textures_oh.pk4' contains:
darkmod
└── map_specific
└── oh
├── oh_ed.jpg
└── oh_local.tga
-or, another attempt-
├── dds
│ └── darkmod
│ └── map_specific
│ └── textures
│ └── oh
│ └── oh.dds
└── textures
└── darkmod
└── map_specific
└── oh
├── oh_ed.jpg
└── oh_local.tga
I even tried a PK4 that included the materials file.
What is wrong and what is correct?
