Sorry if this has been mentioned before, but I didn't see it anywhere else. Dynamic shadows look a little funky sometimes. I don't exactly know how to describe it so I will give a few screen shots. These were taken in Blindabuser's Fantasy Castle III.

No matter where you stand around this teleport it looks the same.

Hehe, I was waiting for that... I encountered the same problem with an FTP server I was hosting.

About your problem... hmmm...
I'm assuming you have dynamic lights and shadows enabled? Model lighting? I don't really know that much about all this dynamic stuff anyway. I'll do some research.

It's not a bug. Those a projected-planar shadows (keyword: planar). So if they run off the plane they're casting on, no more shadow. They're very cheap and fast, though. :)

We already replaced those with shadowmapped soft-shadows in CVS. The planar ones are just a fallback now.

Yeah I just realized that, sorry to bother you with this post. Although when I was looking at the CVS version I noticed the shadow was in a different location... Although it made more sense, so yeah... hooray for soft shadows

Hooray for soft shadows, but they eat up memory like crazy. (At least since I checked out CVS.)

The response to your assertion would be: no, they do not. You are probably confusing them with something else.

Not to insist that I'm right or anything (you wrote it, after all), but something's eating up memory, and the rate at which it uses memory slows when soft shadows are disabled. To me, this'd indicate the soft shadows.

Though maybe "like crazy" isn't the best phrase... It's not quit that fast.
