EXPORT FROM REVIT (.OBJ)
Add Revit material to differentiate different parts.
Meshroom VR uses the different materials applied by Maya to your model to identify the different parts. On each part, you will be able to drag’n’drop a Meshroom VR material.
Be sure that each part of your 3D project is associated with a material.
To apply your material:
Make sure to be in 3D view > Preview
Go to the Modify tab.
Click on the paint/material icon then on Paint.
Once the Material window appears, select the required part to apply the material. Then, click on the right material to assign it.
*It is those colors and textures that Meshroom VR will use to identify the different parts of your model.
