From Mathia Walker: bug fix to LOD ranges in TXP plugin to avoid cracks:

Browse Source 
"I took a closer look at the conditional code in
SeamFinder::seamReplacement().

Because _info.minRange is a double and lod->getMinRange(0) is a float,
the difference will be calculated with double precision. If
_info.minRange is cast as a float it is exactly the same value as
lod->getMinRange(0) and the difference is exactly zero.

So if you change


 if((fabs(_info.minRange-lod->getMinRange(0))<0.001)&&(fabs(_info.lod0Range-lod->getMaxRange(0))<0.001))

to


 if((fabs((float)_info.minRange-lod->getMinRange(0))<0.001)&&(fabs((float)_info.lod0Range-lod->getMaxRange(0))<0.001))

it works a lot better."
