I created a scenery asset with 3DCanvas7. I saved it as an 'im' file and it did so with all the accompanying bmp files. Using CMP  I created a scenery--->mesh-table---->Apartment01. 
It shows up nicely in the viewport. However when saving for config. file I get three error messages:
The texture XXXXXX.bmp is not a power of 2 please resize it. Question: To what size is power of 2?
Second question is once I have the config. file what do I do with it?
Thanks. I have a lot of content which I created for RailSimulator and I'd like to port it over to Trainz.
