Need help with very large models

Hi All,

This is my first post to the forums though I have been reading them for quite some time. The answers provided by many of you have helped make my learning of Blender be very quick. I’m a game designer and find myself in an interesting situation.

I’m currently working on a game that uses a commercial engine and were trying to establish a workflow that is relatively cheap and facilitates communication between designers and artists. We needed a tool that would let a designer throw together the basic shapes of a given level and then pass it on to artists. I can’t use a CSG editor (like world craft) because the engine in question requires all structures that players and NPC can navigate (using AI and such) and walk on to be one big mesh. That is that buildings and landscapes are all connected and built as one huge object.

I had decided on using Blender as the the tool for designers to use to make this base mesh abut have recently run into a snag. As the base mesh got bigger I found that I could not see all of it in the perspective mode. When I rotate around, large chunks of the model disappear as though Blender was optimizing the view somehow. When I scale the model down then I can eventually see all of it. I’d rather not work to with everything scaled down as I must eventually export to DXF for the artist to work with it in Max.

Is there a way to turn off this odd face culling? It’s not an issue with face normals disappearing. This problem is evident in wireframe as whole lines disappear. ANy help would be appreciated.

Shift-F7 over the 3D window.
Increase the ClipEnd value.
Shift-F5 to go back to the 3D window.

Thanks theeth,

I spent a good portion of Friday and Saturday trying to figure this out. searched on every word but “clip”. Sigh, I’m not as dumb as I must look. . . honet. :slight_smile:

It seems that there is a max clip end of 1000 which also appears to be the world view/size limit. Is there any way to just turn off clipping or increase the world size so that I can inturn increase the max clip? Perhaps in the command line or something?

-Allen

No, I don’t think there is.

What you could do is work with a lower scale, and resize before exporting.

If you scale it down in object mode (not edit mode) you can just press Alt+S to grow it again before export

Wow,

Alt-S is just what I needed, thanks phlip. I can can work like this for a while and it will be fine. It would be very nice in future versions of Blender if the limits on the world size would be lifted. It would allow Blender to play nice better with other Apps and would make it much mroe useable ingame design. BSP engines are on their way out and you’ll be seeing mroe engines that require a mesh to be built in a modeler type of programs. This would even be useful if GameBlender is to grow as an engine in it’s own right. I’ve been a big fan of Blender for a long time and would like to see it grow as a game dev tool and find its way into more dev houses. We, for example, are going to be subcontracting other developers in the future and if I can find a way to cut costs by working blender into the workflow (as I think it’s insane to require all artists and designers to use Max) that would just make my day.

Thanks theeth and phlip for the assist.
