I have created rather a large file which I am trying to run using the GE. Everything works fine until the file reaches about 13MB then I can no longer use the GE as it just crashes when I try to run it. Is there a limit with Blender? Is there something I can adjust to fix this? Any ideas or tips for trying to reduce the file size? Please help me!
13mb??? What do you have in there!
How many polys is the whole scene, the BGE can currently only go up to 40,000 Polys per sceen at it’s absolute limit (Before it reaches 0 FPS)
I have a scene with over 250,000 polys… it’s 4meg. How many are in yours?
How do I count the number of polys? I have a walkthrough model of a complete building. Even with the building empty my file is massive…what am I doing wrong? If you want to have a look the file is at

Thanks for any suggestions!
My internet is going sllloooooww, apparently it was going to take 50 minutes for that file to download (4kb/p/h)
I’ll try again now, if it doesn’t work i’ll try tomorrow.
I looked at your file.
You have major wastage in vertices. I looked at a set of stairs and you had vertices there that aren’t required. Heck even you flat landscape had a bunch of vertices that shouldn’t be there for just being a simple plain.
In short you need to rework on all your models and remove the vertices not required.
You have 75055 faces in that house many of them for things that are pointless. All those faces are being rendered at the same time. Blender does not have BSP support like other game engines (Quake 3 etc). So you have to implement a LoD based system into the game to allow it to run. If you wish not to remove the wasted polys/vertices.
Please can you tell me what an LoD based system is? I have tried ‘removing doubles’ from vertices but it didn’t seem to come up with that many to remove. Is there a way of removing faces that are not necessary without manually going through the whole model? Will it really reduce the file size that much?
Thanks for any help you can give me…
Well I was looking at something in your map, it big and round and looks like a bath. This bath has way to many vertices for a game and should be reduced to a maximum of 12. Inside the bath there are some sort of poles. Each with sides of what I believe to be 32 vertices! major wastage for something so pointless. And it not like you only have 1 of these poles but you got like 5 of them.
Those poles could be removed, and replaced with 2 planes interescting to simulate the pole/cylinder.
You have a floor to what I beleive to have something of around 50 - 100 vertices, and the floor is just flat. It could be reduced to a mere 8 vertices.
You even have vertices & faces that will never be seen by the player.
So yeah go through each model and seriously think about them. Remember this will be a game you make the detail with the textures.
It’s not the polys that are taking up 13 MB, if anything, i’m sure it’s the textures, or sounds.
Hmmm…
select your building or whatever that needs poly’s reduced, then go to
Scripts> Mesh> Reduce Polygons
If that doesnt work out, remodel with less poly’s.
Hi Nicky,
Are you importing from another application?
at one time I remember a post about bringing stuff into blender from other applications using the old DXF importer.
The solution was to import .OBJ files… if your external application supports this format ,i suggest giving it a try…
hope that helps.
