Yes there are. If I understood you right the reflection abilities of your models were only set in the preview window of med/wed. These values are only for the preview mode, to set them to your model in the real game you have to write a new material for your model and set it to the model like this:

MATERIAL my_special_mat {
ambient = 50;
//now set the diffuse, specular, ambient and emissive as you want
}

ACTION entities_action { My.Material = my_special_mat; }
