HI Magnus, If you make a Transform node as STATIC then you've told the scene graph that it will never change so will be fair game for the Optimizer. You have two choices if you don't want to have the Optimizer optimize it away:
1) Don't call the Optimizer with the FLATTEN_STATIC_TRANSFORM enabled. 2) Make your Transforms which will be changing as DYNAMIC. Robert.
