Is this the model's problem? However, how can I shrink/scale it down? I have to do this myself and it's a pre-rigged model.

You also seeing that the bottom part of the character is clipped off. Why is that?

I don't know yet because the view and projection matrices seem to be correct as other models are displayed correctly, apart from skinned ones.

Thanks

Hi, I am on another task now. This is memory leaks. I've got 3 memory leaks.
I've heard of other people who used PIX successfully finding out memory leaks

http://creyavaichxxi.awardspace.com/wordpress/?p=218

But in my case, the reported size from the IDE and PIX don't match, I have no clue what unallocated index buffers and vertex buffers are as PIX indicate me.
No ideas what all the magic numbers mean. I looked google and there is only a little information and I don't quite understand.
Could anyone explain a little bit how I can make use of PIX to track down memory leaks?

This drives me crazy...
D3DX: MEMORY LEAKS DETECTED: 3 allocations unfreed (28024 bytes)
D3DX: Set HKLM\Software\Microsoft\Direct3D\D3DXBreakOnAllocId=0x5f5c to debug

 

I've tried to create a key in the registry, but the call stack went to some mysterious place, like somewhere in QT


Thanks
Jack

One slow but always working method is to disable one feature at a time until the leak stops. For example, start your engine without loading any models to see if it is connected to the model.

Hi,

in my case pix also reported strange things. It looks to me, when you forget to release one thing, PIX will report also lot of other "unreleases" that aren't relevant. E.g. : once i forget to release one texture, but PIX showed me around 10 unreleased things, including index and vertex buffers. After releasing of texture, all other leaks dissapeared.

So i woudn't believe PIX in everything it's complaining.
