Hi,
I am working on a big office interior project right now.
The building is too big that I need to use section boxes to work room by room.
BUT, I have discovered that when I am moving to another section box to work on another room,I re-sync my Revit Model to just make appear the new section box. Then, when I go back to the previous section boxe, all the materials I have applied previously dissapeared from the model…
Screenshots below
1> Scene with material applied
2> Scene after I changed the section box (all my interior design wall and element have dissapeared, just remain the elements from the linked revit model, Structure, MEP etc)
3> Scene when I come back to this section boxe
All the elements that have dissapeared previously when changing the section box come back with their Revit original materials…
This is a HUGE issue for me, I can’t work with the whole 3D model of the building at once, it is too laggy for my pc…
But shouldn’t the material already applied to the model and should them be saved when re-syncing ? I don;t understand why I have this problem ? Is it a limitation of D5 render …?
Please help me fix this problem
