Texturing

[DRedshot]

yeah that above link should help, but if you are still stuck, heres what i meant: download OpenCollada from OpenCollada.org , go to window --> Settings/Preferences --> Plugin Manager, in Maya, And enable MayaCollada. Open your model, export as OpenCollada. Export to Desktop>MyEntityFolder
Make the Folder name the same as the .dae name (so if your models called chair.dae call your folder chair) copy your textures into this folder and change their names to for example
"chair.dds"
"chair_spec.dds"
"chair_nrm.dds"

At the end this should be your folder structure
Desktop-->
chair-->
chair.dae
chair.dds
chair_spec.dds (optional)
chair_nrm.dds (optional)
chair_xxxx.xxx (optional)

The _spec tells the game that the texture is specular, this is the 'shiny' effect you get on entities when a light is shining on it with alpha (i think)
_nrm is the normal map, i've forgot what this does. basically, you will know if you have made a specular or normal map, but they are optional

now copy the folder to
amnesia - the dark descent > redist > entities (skip redist if on steam)
open material editor, and click diffuse, select your texture and repeat for all the other files (specular) (normal maps) (height) then save the material file in your 'chair' folder for example. then if you open model editor, click import mesh, and add the bodies, it should show up with a texture
