Rendering with Microstation and AECOsim in Microstation mode

I am trying to render the same way I did with Microstation using AECOsim in Microstation mode. But it doesn't behave the same.

I use external .mat and .pal files for rendering, and AECOsim doesn't load them when I open a file like Microstation does.

This is what I get when I open the file in Microstation.

And this is what I get when I open the file in AECOsim.

How do I get AECOsim to open with the correct palatte attached ?

I have to manually attach it every time I open the file and also when I change models.

Regards

Michael.
