Illegal Capacity when trying to extract meshes (v0.3.4) #148

Open Devilin-Pixy opened 8 years ago

Devilin-Pixy commented 8 years ago

When extracting Unity .assets files I get a java.lang.IllegalArgumentException as soon as it tries to extract meshes (ClassID: 43).

Error thrown:

Might want to guard against negatives being passed to the ArrayList I guess. The OutOfMemory can most likely be fixed by giving Java more memory in the batch file.

Hope this can be fixed, because I am mainly using this nice tool to extract models in .obj format.

The out of memory is actually caused by wrong type information. More memory won't solve the problem, only updating the type information can fix it.
