Hi Tom
Looks like an unfinished runaway! LOL.
Please check if your file C:\TORNADO\TORNADO\AMP\MAP3\
TREE3.BIN is the original TREE3.BIN, or if it is the modded TREE3.BIN from the
http://dogsofwarvu.com/forum/index.php/topic,5046.msg29189.html#msg29189 post.
If your TREE3.BIN is from that post, then see if you can remove it by overwriting it with the original C:\TORNADO\TORNADO\AMP\MAP3\
TREE3.BIN.
I am trying to see if this is the cause of the strange artifact or it is caused by something else.
Oh yes, I just realised that this file was also modified (as part of the tree mod):
C:\TORNADO\VISUAL\MAP\SECTORS\
OBSECDEF.INCThat OBSECDEF.INC file is itself used by C:\TORNADO\VISUAL\SECDATA1.ASM.
So what I have just done is to restore the original 1993 C:\TORNADO\VISUAL\MAP\SECTORS\
OBSECDEF.INC and I have recompiled C:\TORNADO\VISUAL\SECDATA1.OBJ and relinked the entire FLIGHT.EXE.
UPDATE - 22 June 2018, 12:50am Kuala Lumpur timeAnd there's more! These 4 files were also modified as part of the tree mod!
C:\TORNADO\VISUAL\OBJECTS\GROUND\
COPSEA.INCC:\TORNADO\VISUAL\OBJECTS\GROUND\
COPSEB.INCC:\TORNADO\VISUAL\OBJECTS\GROUND\
COPSEC.INCC:\TORNADO\VISUAL\OBJECTS\GROUND\
COPSED.INCA 'copse' is a cluster of trees. So these four files have something to do with the tree patterns and density.
All four INC files above are used by C:\TORNADO\VISUAL\GRNDOBJ1.ASM.
So I have just restored the original COPSEA.INC, COPSEB.INC, COPSEC.INC and COPSED.INC files, recompiled C:\TORNADO\VISUAL\GRNDOBJ1.OBJ and RE-linked the excutable FLIGHT.EXE.
Try
RE-downloading the attached latest FLIGHT.EXE (that doesn't have the tree mod) and see if that offending and deceptive artifact is still there.
