Title: re-populating
Post by: Lady of the Lake on December 29, 2014, 04:33:33 PM
Am I the only one having trouble with populations?  Since the update, every time I change anything and want to do a crop render......everything re-populates.  I have some pretty large populations in my scene so I am sitting here waiting for 5-6 minutes every time.  Didn't seem to do this before.

?????

Thanks
Lyla

You need to use the population cache..............makes things a lot easier.  ;D

There a Wiki page here: http://www.planetside.co.uk/wiki/index.php?title=Population_Instance_Caching

I don't think there should be any changes that would affect things they way you're reporting. Do you happen to have access to the previous (3.1) version so you can install that and test for sure?

No, sorry.  But I will definitely try the instance cache.  Didn't know about that.  (slow to learn... ;D

Thanks for the link, jaf.

I'm having the same issue right now, I was suspecting it was a bug (there was a bug just like this in one of the final versions TG2)
in previous versions of TG3 this didn't happen I think.

now I just instance cache most of the time when rendering.

That doesn't seem to work too well for me as I am constantly changing things so have to re-do the cache all the time.

Zlain, I believe it is working as designed at this point. Can you describe the bug you think you're experiencing?

Lady of the Lake, there is no way around having to redo the cache if you make a change. That's a fundamental limitation of a population cache. You should not enable Population Cache on any population while you are still frequently adjusting it OR any other shader that might affect it (for example displacement or mask shaders). Population Cache is meant to be used only once a population is "finalized" or nearly finalized, and thus you can "fix" the population instances where they are and not have to repopulate them again if, for example, you reload the scene, or send it to a render farm, or are rendering an animation, etc.

Yes, it is helpful.....just not as much as I wanted.  ;D    My workflow is probably very unconventional.  LOL  If no one else is having the problem, it must be me
