Assert: "Error alloc too large, increase frame size!"

#1 This is obviously not a vanilla mission. FrameAllocater is used for memory which is being allocated for a short time then unallocated, what it does is allocate a big chunk, 3 megs by default, and then pass out little bits of it to whoever needs it.

To increase the frame size, look in main.cc, there should be a FrameAllocater call, the argument is ( 3 << 20 ), IE 3 megs. Increase it.

#2 One thing that can cause this is a too high view distance on terrain.

#3 Aha! that was it; too big a view distance. Thanks both of you for your quick answers.

#4 Interesting fact: The TSE terrain is much less susceptible to that problem. :)

#5 I'm getting this same problem with TSE when I tried to port the RTS stuff over to it. The game comes up fine at first because the initial view angle causes only a fairly small amount of terrain to be in view, but when I try to tilt the camera up to see the horizon, I get this error. I tried increasing the max alloc size from 3 megs to 4 megs but no dice.

I'm still using the same .mis and .ter files that I was using with the stock RTS stuff. Do I need to modify these files in some way for TSE?

The "visibleDistance" parameter in the Sky object is set to 600, in case that matters.

Here's the stack trace:

#6 *bump* (not to be a pest or anything) :-)

Can anyone shed some light on why this happens in TSE but not in TGE/RTS? Any tips on debugging it? For that matter, since it's really a TSE question now (for me) would it be better if I posted it in the TSE forums?

Thanks!

#7 Yes, TSE forums are place to go.

Did you change the blockSize or anything?

In general things like the terrain will have their usage go up exponentially with higher view distances. Try doubling or tripling the frame allocator size.

#8 Hi Ben. I'm using the frenzy.ter and frenzy.mis that came with the RTS kit, but I changed the terrain to use a completely flat heightmap. I also changed the squareSize from 5 to 8, but I don't think I changed anything else. I'll try bumping up the allocator size and if that doesn't work I'll post this over in the TSE forum. Thanks!

#9 Have you tried sticking a tiny little bump somewhere on the terrain?

#10 Ummm why would that make any difference Ben?

#11 Because of certain calculations done using the height range of the terrain, of course.

(On another thread, it seems the problem might be a borked terrain renderer codebase...)

#12 I got the same error,
and for me, its a similar problem..i didnt change the height of the camera, but the square size of the terrain block, so i ll have more details on it.
it crashes. not immediatly, but after some moving around.
also, another thing which occurs is, that im unable to paint anymore, the brushes have blue color and no effect while painting textures. but that's for another thread.
greetings

#13 What is your square size, and whwat is your view distance?

#14 It appears at all squaresizes smaller then 6 und my view distance is the standard one, i didnt alter it.

#15 For the iPhone I increase it to 4096 * 1024 in the lines just above that to overcome the error.
