Rule The Rails by Brainbombers

Hi all
I’m using Blender to create models for the Rule The Rails program but…
RTR will not display the models created even though DXViewer will.
I think the format of the x file from Blender is not correct.
I’ve created a model using the free program from Delgin and it works OK
but it does not have any animation features.
Can someone help with this issue, because I would rather use Blender than anything else.
