This one's complicated
Using the OE, export rdfct1x1m.
In the export folder I have the following files:
1 rdfct1x1m.ac
2 RDFCT1X1M_EV_d.txt
3 RADARF1M.bmp
4 RADARF1M_A.bmp
5 RADARF1M_E.bmp
6 RADARF1M_N.bmp
7 RADARF1M_S.bmp
8 RDFCT1X1M_CL.bmp
9 RDFCT1X1M_EV.bmp
Now the only change I make is to rename file number 1, the rdfct1x1m.ac file.
Rename it mytest.ac.
Using the OE, Convert the ac file, mytest.ac. Remember, I didn't change anything inside.
My userlib folder now has the following:
mytest.shp
RADARF1M.htx
RADARF1M_NEP.htx
I remembered before this patch of getting _CL and an _EV.htx files as well, they're not here in this patch after a simple conversion.
I install the three files in my texsrc folder and try to install mytest into a terrain with the TE and it crashes upon clicking OK.
I go back to the OE and create a sq tile with one building. I name it mytest2.
I install the mytest version of the radar factory ground into sq tile mytest2 and it looks good. I add a building and build it.
Now I get the two missing _CL and an _EV.htx files in both the userlib and newshps folders. Except for the difference in upper case and lower case, they appear to be the same at 258 KB.
But wait, in the last OE, these four files would have both been RDFCT1X1M_CL.htx and RDFCT1X1M_EV.htx (except for the case) and now they're named MYTEST_CL.htx and MYTEST_EV.htx
I put the six files into my texsrc folder. (mytest.shp, RADARF1M.htx, RADARF1M_NEP.htx, mytest2.shp, mytest_CL.htx, and mytest_EV.htx)
The sq tile shape is mytest2 in the Shapes List
I place it into the terrain but don't click ok yet.
I don't see anything except the building I placed in the OE until I get very very close, then the sq tile ground, mytest, shows.
I click OK and I'm surprised when it doesn't crash the TE.
Now I have the same exact problem I've had with my city0.
Remember, I didn't touch any of the internals here.
At very long distances, and at very close range the ground texture shows, but not for most of the viewing distances in between, it's gone.
I build and test the terrain just to confirm the same problem is in-game.
You can see almost the same effect with the city in avaeto except I managed to force a reduction of the problem by changing the LODs.
