Hey all,
I'm trying to load an obj model into Gem OSX and it just seems to crash. The packaged venus.obj file works fine. Here is the PD output:
_glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". _glmFindMaterial(): can't find material "vn". *** malloc[500]: error for object 0x20c6690: Incorrect checksum for freed object - object was probably modified after being freed; break at szone_error
gdb tells me:

I've attached the offending obj file (I tried three that all don't work)
Sorry about the anoying "watchdog" messages interdispersed... but thats another email to pd-dev.
Thanks Ben

That seems to be the case with some .obj files. The problem is in glm not in GEM's use of it. You might want to contact Nate Robbins who wrote glm.
_glmFindMaterial(): can't find material "vn". *** malloc[500]: error for object 0x20c6690: Incorrect checksum for freed object - object was probably modified after being freed; break at szone_error
You can do one of two things: try and remove all the material references in the .obj file or comment out the material loading part of glm. We don't even use the materials in GEM anyway.

gdb is telling you that you need to be me in order to accurately debug this problem.

so is this a model of britney spears or times square?
