It was indeed a bitmap output. Great to see you already have a handle on the issue!

Hi there,

For clarification, are you exporting a bitmap or a heightfield?

EDIT: I've confirmed there is a bug in the PNG bitmap exporter for sizes that exceed 32bit integer size. This will be fixed shortly. Height field export is unaffected.

Hi, is this fixed? I tried exporting a 16 bit png and I ran into an out of memory error, however a 16 bit .tif export works fine, so that leads me to believe this bug is still not fixed. Unless something else is going on. I have 16GB of ram and my page file max is set to 24,xxx (should it be larger?)

I am using a 16385 x 16385 resolution. Thanks!

I believe there might indeed have been a bug in a temporary buffer allocation within the png writer for very large (larger than signed integer size) areas.

I have fixed this bug and it will roll into the next RC/final. A quick look through the other formats didn't reveal any similar issues; you should be able to export as a TIFF for example, in the interim.

I tried only16 bit .png file format so far. I`ll try all the other ones and I`ll let you know.

Hi there,

Although these are large world sizes, you have the memory, so there should not be any obvious reason it won't work.

What format are you exporting? There might be a format specific bug in the file exporter.

I tried to export a 36K pixels heightmap and even though I have 64GB RAM on my system I wasn`t able to do that. The estimated required memory is less than the amount memory I have installed but it still gives me the message that there`s not enough memory. In task manager it shows even less memory used than the estimated one. Isn`t possible to save a 36K heightmap with 50GB free memory left on my system? Or is it a bug?
