Creating a robust lightmapper which can handle large worlds is no easy task, and I can report that the bulk of this work is now done. What remains are hundreds of little bits and pieces that either need to be discarded or added to the whole in their correct place. My own tests are good and I can give it pretty much any level and it rarely gets above 600MB of system memory usage for typical levels the size of the Concrete Jungle. Today I have been mainly contending with a crash report that happens on one machine right at the end, after a successful LM process. A very illusive bug that can only be reproduced on one machine so it's a case of sending version after version until the cause is known.
Half way through the day I received this holiday screen shot, which cheered me up and spurred me on. Notice the lightmapping, a nice touch ;)
Going to walk the dog and then return to make another build. I have already made one for the internal testers, but will continue bouncing versions to find this mystery crash and of course do a few more tasks that I can do before my early night. Big (and final) meeting day on Tuesday but hopefully we will be cutting it to half a day which free up the second half for more testing and coding. Getting there :)
