Title: NullPointer @ GLRenderer.drawVertexArray
Post by: raft on June 30, 2010, 01:05:23 am

any ideas what may cause this ? i've tried to create a test case but no luck since now.

Code: [Select]

these are the previous log entries, if helps. btw, these objects are cloned from a master. the master is built indeed but warning still complains about they are not built yet.

Judging from the line, it looks like as if it's trying to access a null texture...pretty strange, i've currently no idea how this can happen unless flushing the TextureManager interleaves with rendering or something.

Try to set Config.aggressiveStripping=false; and see if that helps...
