Would like to say that is Matt's problem, but your problem isn't easy to analyse via internet.

Be sure to make not too much steps at once! One step after another! Each step documented in your post.

First steps has to be: Start a level of Sphere! Without modifications! With all the conditions fullfilled mentioned in the Readme!

Does this work? Is everything as it should be?

Then start the other level!

Does this work? Is everything as it should be?

Change the parameter which changes from bump to parallex. And restart the level! Control each change by starting the changed level to see wether it makes a difference and which difference it makes!

In that way, change the level's models step by step, and don't do the next step before your step has been successful...

Not sure wether you needed these advices, but your last post was too short to help a helper!
