[solved]Fatal error

[Pixelatedvertex]

When trying to render one scene, I get the following message after the export has been finished and the Frame buffer is about to start:

ERROR: Fatal error in mtl-XML file: 'Scene.mtl' : Attempting to redefine material: default

the material called 'default' is just a default corona material with the diffuse color changed to around 80% grey. The material is applied to most objects in the scene
Any ideas where to start looking for a solution to this error?
thanks in advance

Rename your default material as the exporter already defines a default material.  I will try to fix this but will take a few days.

Cool, this solves the problem, thanks!
