Export taking very long time

BenLeslie1 — Fri, 08 Nov 2013 06:34:06 GMT

I've just upgraded to a fully licenced version of CE 2012 (having previously been using 2011 then a trial version of 2012) and I am trying to export from this fully licenced version for the first time.

The scene is quite simple and it exported with satisfactory haste in previous versions. I have tried to export a few times, this morning I have been here 45mins and it still says "operation in progress..." and I am still waiting. CPU Usage is piddling along at 5%, I have closed other programs and rebooted and I am still waiting.

Is there anything I can try to speed this up?
All assets are on my local drive however the licence file is on a network server - does CE look at the licence when exporting? Other aspects of the program seem to run normally.

Hi Ben,

Getting any error entries ?
What file format are you exporting to ?
How many polygons ?
How many materials approximately ?

Please try to track the issue down layer by layer and rule file by rule file ?

Could be many things, theoretically.

Well, I can make it work but I'm not any clearer on what is causing the problem - it feels like I have to teach CE how to read my rule file by showing it the file in bite sized pieces.

As per my first post - if I start CE and try to export using the whole rule file it takes very very long time (it took ~6hours to export 1 building)

However, if I comment-out 3/4 of the rule, save all and generate models,
then comment-out 1/2, save all and generate models,
then comment-out 1/4, save all and generate models,
then use the whole rule file save all and generate, my model exports in 1.4 seconds. If I do it like this it is very quick to export.

I seem to have to do this commenting-out in at least 3 steps (1/3, 2/3, all) but doing it in quarters seems to be quicker.

I will continue to try and specific problem with my code but at the moment I'm at a bit of a loss. Could it be a caching/memory problem?

...and to answer you questions:
no error entries
exporting to collada
I'm using 25 materials (but I have various case statements that allow for up to 125 different materials)
3144 polygons

Hi Ben,

That seems odd indeed and should not be an issue.

Can you check the model hierarchy for one of those models ?

Can you create a minimal project on which you can reproduce that behavior and send me the project ? If interested, send me a PM.
