New textures for hpl2 Level Editor

[DnALANGE]

static objects or PLANES?
Here we go for Static Objects.
Look forn the NAME of the SO (Static Object)
Then open the .DEA with NOTEPAD++ for exzample.
Look what .MAT it is using.
THen OPEN the .MAT and look what .jpg or .DDS it is using.
It can easely be 1 2 3 4 5 lines.
Then find those files and you will see all those .dds or .jpg Then open those witch you prefer with Paint for example and channge it to what you want.
That is 1 option.
The other is to open the .DEA with MAYA2011 and change it in there.

NEVER OVERWRITE -> ALWAYS MAKE A COPY OF THE ORIGINAL FILE!!!
AND CHANGE IT FOR EXAMPLE TO CAVE_CUSTOM!

------
About creating your own .mat files (textures) for planes.

ALWAYS make then a POW 2 SIZE. ( meaning -> 2x2 4x4 64x64 512x512 etc etc.. OR like 512x256 1024x512 46x12 like that) IF NOT, the editor will crash!

Then;
IF you have the file opened in like paint.. Then save as .JPG and put it in YOUR MOD\STORY.
open the material editor and look for your .JPG \ .Tga (or just open an original .mat file and just change the ... in YOUR .jpg)
ALWAYS make it SOLLID FUSE (that is the best for walls and floors)
then you can change the ALPHA\Diffuse etcetc..
What i suggest is make 2 named ;
1IFFUSE + SPECULAR and save
2Iffuse ONLY! and save.

The Diffuse is just the texture
The DIffuse + Specular is ading a lightsource idea. looks great for floor tiles witch shine a lot.
--
Try saving the file in the same map\folder as the .JPG or.Tga (more easy to find everything for yourself)
Then create a plane and select the file you created.
Finished!

Hope this is what you wanted.
Good Luck!
