The beachhell isles terrain has all the .bmp terrain files included by default in the folder if your EAW configuration graphics setup is set to terrain detail medium or low just use the main folder set, otherise if set to HIGH detail then you would need to use the 3 extra tiles
(unless I goofed up.. lol!----------------------------

So if you don't see any anomalies then you are good to go with no cahnges!

24-bit Terrain notes
24-bit (16.7 million color) terrains can be used 

They have to be .bmp files, 24-bit 

You make the terrain tiles 256 x 256 size for the BN tiles (note see exceptions below)
name them instead of .ter as example:
bnforst1.bmp

(note; to be safe you will still need the .ter files as in some graphics setups the distance tiles will be used if the new .bmp tiles are not the correct size (see below))

The LR 24-bit tiles will need to be 128 x 128 size (with exception of the 5 new tiles enabled see later notes)
named by same convention i.e.:
Lrforst1.bmp

note by RAF_Roy: ---
There are some exceptions for graphics settings:

field3 
alcty6 
base 
field9 
river3 

they all need a 256 x 256 size LR .bmp tile for the distance view 

in other words with a 256 x 256 BN tile set and including 128 x 128 LR distance tiles at the same time, the 128 x 128 distance LR .bmp files are used for the regular tiles in long range views, but the exceptions are with the new tiles.. they do not work if 128 x 128 , and thus the default .ter tiles show up

Exception to above;

with graphics setting med or low terrain detail a 256 x 256 size LR .bmp is used for Both views! 

this only aplies when using graphic terrain level settings of medium or low; 

...for some reason only the 256 x256 LR distance tiles will render, for BOTH views for the 5 new tiles only (in other 
words the presence of the 5 BN tiles does not matter, they are not used. 

Really its not a problem, just as long as modders are aware of it. 
You just need include the 256 x 256 LR tiles for the 5 new tiles in a set if you add it to a scenario. or possible a second optional folder containing the alternate files.

airfields and 24-bit
64x64 size may be needed for some airstrip as seen in this copy of Aldo Britt44's test pics:
