The case of the phantom unit portrait

Hi all.

I have a problem... In my map which I am currently working on, unit portraits appear blank in-game, just a plain black background. I really have absolutely no idea what's causing this and would be thankful for any advice given. Another problem, in the same map, is that units' HP aren't being updated regularly under where the portrait should go (i.e. the 'current life/max life' bit) It is only updating very periodically, and so a hero could apparantly have 1000 hit points one minute, and then be dead the next, which is a bummer as you can probably imagine.

I've never heard of a problem like this. Could you tell us more about the map?

For starters, what models are you using for the units that have the portrait problem?

Also, are you running any triggers on periodic events, like "Every 0.50 seconds" or such?

Anything else peculiar about the map that might give us a clue?

Or, perhaps attaching the map will also help. -.-

You don't turn on letterbox mode anywhere in your map do you?

4 digit HPs and more can get a bit dodgy as they don't fit sometimes and thus don't display properly.

OK, I'm not using any custom models, skins and so on, and the problem occurs for all units (or at least all player controlled units) I'm pretty sure there are no periodic events, although I will have to check. And yes, I do use letterbox mode, (and portraits are showing fine during my cinematic cut scenes). I can't think of any abnormalties, but then I'm no triggering genious so I wouldn't really know what to class as 'perculiar'. Thanks for the replies people :D

If you're using Letterbox mode, look to see if you're switching to or from that mode over 0.00 seconds, and if you are, try 1.00 or even 0.01 instead and see if that helps.
