Bug in clipfly for emulated cliptextures with more than 18 levels?
I have a 25 level (16777216x16777216) cliptexture that I am trying to
display. On InfiniteReality clipfly loads this texture perfectly, but it
fails under emulation on the Octane2 detailed below. (.ct file listed
below that.) Under emulation I get correct results up except in the
rings that display the texture levels that are larger than
131072x131072. if I limit the levels to no larger than 131072x131072
texels it works. there's a screenshot at
ftp://ftp.cmf.nrl.navy.mil/pub/melody/ctemulateerror.jpg
The displayed imagery (aerial photography) appears to be correct in the
sense that if I turn off gridification I can recognize objects on the
ground as being in the correct objects in the correct location, but the
resolution is several levels too coarse. It's like I'm looking at the
ground through a lens that coarsens the resolution dramatically anywhere
the texels are (or should be) coming from the levels finer than
131072x131072 texels. Is this a bug, or is the .ct file missing
something emulation needs?
thanks for any info.
