Hi,
I am using flex profiler to track memory leak problem, and came across this memory leak due to Dictionary Object usage in papervision. Where can I get the latest papervision swc with the patch? I am using Papervision3D_2.0.883.swc for now.

Hmmm actually I seem to have resolved the problem. I was creating a single point light and flat-shade material in my constructor and applying this same material to each instance of the lathe object. However if I create the pointlight and flatshader along with the object as like in your example it seems to work fine?

Hey there I am also experienceing a memory leak. I am trying to use the zavoo graphics3D package to create a lathe object. If I run a test script like yours but substitute the sphere for a lathed object the memory just keeps on going up.

Any ideas?

Hi Seb,

I think i’ve made some progress with the memory leak on my part but there still seems to be an issue within PV (in my app anyway) which you already know about. I think the problem i addressed is to do with materials not being tidied up so maybe it’s the same thing within PV. Out of interest is there anywhere i can submit a bug? There seems to be an issue when using MaterialList.clone() whereby if i’m cloning a list with interactive materials after cloning they are no longer interactive.

Any ideas???

cheers
Doug

Hi Doug,

that definitely shouldn’t be happening! There was a recent problem with frustum clipping but I think that’s been cleaned up now. Send me your code and I’ll take a look.
