Hello Spider,

I'm not sure what to do with the OCC but here is the way you can load the other four.

 

Put the DISP in the Alpha channel of your COLOR. I use the DirectX Texture Tool that comes with the DirectX SDK. All you have to do is load up the COLOR map and then choose file menu - Open on the alpha channel of this Surface.. the DISP file, then save. (Just a side note the DISP might need to be made a negative You can do this in a program called IrfanView click on image menu then Negative )

 

Put the SPEC in to the Alpha channel of your NRM using using the DirectX Texture Tool as before. (Just a side note to get the normal map looking right in the material editor I had to flip the colour channels. You can do this in a program called IrfanView. Use Image/swap colors and then experiement with them as I can't remember what colors needed swapping. Do this before you add the SPEC into the normal map.)

 

Then write a mat file called brickwall01.mat . You can do this using the Material editor in Leadwerks or just copy this code.

 

texture0="abstract::brick_wall01_color.dds"
clamp0=0,0,0
texture1="abstract::brick_wall01_nrm.dds"
clamp1=0,0,0
blend=0
depthmask=1
depthtest=1
overlay=1
zsort=1
cullface=1
castshadows=1
specular=0.500000000
bumpscale=1.00000000
gloss=0.500000000
shader="abstract::mesh_diffuse_bumpmap_parallax.vert","abstract::mesh_diffuse_bumpmap_specular_pom.frag"
shadowshader="abstract::mesh_shadow.vert",""

 

Is this how it is supposed to look?
