Blender crashes a lot in realtime

Game Engine Game Engine Support and Discussion
1

I am making a game with Blender, but is impossible to work because it crashes a lot! I don´t think it is the computer ( i have 8Gb RAM, 4-core processor, GTX 650), so i think is a problem in Blender.
But is a problem in the program or in the installation? Is possible to improve the stability in realtime?
And no, I haven´t a lot of vertices/objects or big textures in game: only 5000 vertices, a 1024x1024 exture and a simple cartoon shader.

What version of Blender are you using? Have you tried a more recent version from the Buildbot or from the homepage itself?

3

I use the 2.69, but I will try to download a newer version.

4

I download the lates build of 2.69 version, and it continues crashing.
I installed it with the installator. I don´t know what i can do for solve the problem.

5

Try the downloads from the Buildbot, which are as recent as you can get without compiling it yourself. 2.69 is pretty old at this point - even the release candidate. There were some bugs that caused crashes that were fixed after 2.69 (and probably the 2.7 release candidate).

6

Try downloading the latest drivers from Nvidia for your graphics card. Having an outdated/buggy (or not having a) version of OpenGL often causes Blender to crash. Also, try a stable build of Blender, as SolarLune suggested.

EDIT: I think these are the latest drivers at this moment - http://www.nvidia.com/download/driverResults.aspx/73780/en-us

How many polygons vs what gpu/cpu?

To my opinion, there could be 2 reasons:

  1. You are using a specific function that crash your system. Try using on another machine, if it don’t crash, that’s not this answer
  2. Your configuration is not safe or is not compatible with blender (a problem of graphic driver for example).
    When i use blender, it crashes some time, but not more than other softwares.

Thanks for all the support!
I will try to actualize the drivers and download a newer version.

10

Is it crashing on the particular blend only? or is it crashing in general?

If you can narrow down the situation you can fill a bug report. They are usually treated very seriously.

11

It crashes on the particular blend. The strange is that the Blend don’t contains a very heavy charge for the computer.
I loaded heavier files with Cryengine and Udk, and it worked fine. So, i think is a Blender problem.
Anyway, this is the Blend file:

Blender crashes when I close the Game Engine. Even in solid mode.

12

Impossible! I download the drivers, the newest version of Blender and it continues crashing! Even in wireframe!

13

Crash have nothing to do with work load. They happen because of some un-handled problems.

I’m going to look at your file

14

The file runs fine at my system. Tested with 2.68 and 2.69.

But, I discover a bug after the game run.

  • open file
  • start game <p>
  • end game <esc>
  • choose menu/help/operators cheat sheet -> The console shows some Python errors
  • in text editor select he operators file -> trace-less Crash

This is repeatable with this file, but not with others. I can’t tell is this is the same cause as you discovered.

15

I open the Operator list.Txt, but i don´t know what I must do.

16

Try importing (append) all objects and scripts into a new empty blend. Does it still crash?

17

Then it is something different. In that case - no I can’t reproduce the crash you discover (I assume it happens while the game engine runs or when you start the game engine).

Martins suggestion is the next step to narrow it down. Sometimes the blend contains some rubbish the BGE can’t deal with. if that does not work, try to append just a part of the original file.

18

I try to append the character and the armature, but it continues to crash.
Buuut, its true that only crash when I finish the game engine the second time that I start it.
So, the bug must be in the armature or the character.
This is the new file:
http://www.pasteall.org/blend/27660

19

Try installing C++ redistributable 2010 SP1. Our clients that don’t have that installed on 2.59 get periodic crashes with the BGE.

20

Running 2.69 under Mint 13 it segfaults after hitting Play->Escape a few times. Crashes on escape.
Fresh build from git: Same

No idea how to fix this, aside from taking out the armature.
You should probably submit a bug report after reproducing in a fresh file.
Here’s my crash output:
