Materials need to be set in your Revit model in order for them to appear in Enscape. Double check that this has been applied to your walls/floors/ceilings and your other components. It looks to me like everything is set to "Default" material in Revit which will appear grayish white in Enscape.
Hey alexjemalc , thanks a lot for your inquiry. 
Excuse me if I'm missing something, but comparing the microwave rendering done in Revit with the preview output of Enscape, I can see that the textures actually seem to be applied in Enscape, if you look at the clock and buttons/menu for example:
In that case, would you be so very kind as to send me a further rendering from Revit alongside a screenshot of Enscape again, from a scene/perspective in which I'll be able to see the mentioned missing materials? Also, a screenshot from the corresponding Appearance tab (in the Material Browser) of a material which seems to be missing would be great as well. That would be very kind and helpful, thanks a lot in advance!
There are a few Enscape settings we may want to make sure are correct (for what you're looking for)
In Revit, Enscape Tab>Settings
General Tab>Mode>NONE
Image Tab>Saturation>100%
Advanced Tab>Material Selection>APPEARANCE
DraftingDave Thanks for sharing the right information.
alexjemalc Please check these settings.
And please have a look at
