Tile size is a bit huge here, as big as page size ?
do you use originial ps_height1k.gen.cfg ?
If you made changes, can you post them here ?

ok.
So there's a bug somewhere.
Can you try the same map using mapsplitter but disabling batch mode

yes.
it should.
did you try commenting the blur pass in maputil (even if you don't use it) ?
tuan kuranes
04-10-2005 17:16:46
mmhh.
You could either debug and find the problem or Perhaps you should wait a bit the backport of cvs mapsplitter to sdk compatible mapsplitter. (or get the port from barnabe42...)

any1 got it running on linux??
...just wondering cuz:
void CNoise::Init(const uint nDimensions, const uint nSeed)
{
m_nDimensions = MIN(nDimensions, MAX_DIMENSIONS);
CRandom r(nSeed);
uint i, j;
for(i=0; i<256; i++)
{
m_nMap[i] = i;
for(j=0; j<m_nDimensions; j++)
m_nBuffer[i][j] = (float)r.RandomD(-0.5, 0.5);
Normalize(m_nBuffer[i], m_nDimensions);
}
uchar k;
while(--i)
{
const int l = r.RandomI(0, 255);
SWAP(m_nMap[i], m_nMap[j], k);
}
_fpreset(); // Bug in CRandom! Causes messed up floating point operations!
}
_fpreset() doesn't exist on linux
