Hello sir/miss,
I wish or perhaps Autodesk could put nor provide Clay Render/View which very useful for architecture students to showing their ideas in a proper and nicely 3D model in render. Students are always searching for 3rd party engines to provide the tool nor effect that help to enhance their visualition and presentation. Wish Autodesk could provide it in Revit awhile 3ds Max has it in their engine.
Did you even look at the solution provided? There is no need to change the material of anything in your model. The only thing you need to do is add a future phase to the project, then right before you render, change the phase of the view to this future phase. This will effectivly change all of the elements in the model to "Existing" elements and they will have their materials overriden to whatever material is set as "existing" (usually some kind of white/gray). It is literally about 4 clicks total to set up and then one extra click right before you render. 5 clicks that is it.
In reality, the phase override solution is a stop gap measure, and not trully effective. No one really wants to change all their fenestration and emitters to
clay as well, totally useless. Revit really needs to get on board to match other rendering engines in this regard. A simple check box
on the render to cloud box that allows a material override of your choosing, but does not touch glass or emitters. If Maxwell can do it, im sure
Autodesk can find a way.
Vray 3.0 for Revit has a feature for this.
Override for opaque materials
Override for transparent materials
It provides a 1 button solution that is fool proof!
Autodesk would be wise to adopt this feature.
