[UT] Moving light object crashing renderer

[geogob]

I've been trying something new with the old UT. well I don't know how new it is, but it's new to me anyway.

I have a light object moving around a level (it's being moved around to follow another actor). The light effect used is LE_NonIncidence.

Now what happens is that on many levels, it crashes the render. Sometimes as soon as the light is spawned, other when it goes to a certain area.

In game what happens is that first the screen becomes black, although the HUD is still visible. AI still works as bots keep on playing. So the game is not frozen. After a long wait (minutes long - and a few Gb of RAM used), you finally get a GPF.

Anyone ever encountered that? I saw similar error with mapping issues, which were solved by recompiling the level. I, obviously, can't do that.

I was considering using ambiant light for an projectile actor instead of using a light. But I'm not sure how this would be very differently.

Here are highlights from the log:

Interesting (and very long log). Thank you for your suggestions.

EDIT: oh yeah. Just though of a relatively important detail... Chris Dohnal's OpenGL

Well. I was not very explicit on what I was working on. Sorry about that -_-

It's a M583A1 Star parachute Flare, a 40 mm grenade to be launched by M203 or HK69 (Infiltration). Basically a launched grenade that eventually becomes a flare that slowly moves down until it burns out (~40 seconds).
