Hello, I am new to Twinmotion and I'm still playing around it. I just imported my SketchUp model to Twinmotion by the SketchUp model to a fbx file. I'm trying to add a material to a wall that I just added over the model wall but the whole models gets painted. I've checked my SketchUp model to see if the added wall is grouped with the rest of the wall but is in their own group only, so they are separated.
Can someone please help me? I'm still using the trial version.
When you imported your model into Twinmotion, which collapse option did you have selected? If you have the Collapse by materials option selected, then any objects within your model get grouped into a single object, so if your whole model was sharing the same material, then applying a new material will change it for the whole model.
The way to change this is to re-import the model using the either of the other Collapse options. Keep Hierarchy offers the most control and keeps all objects separate as they were in SketchUp, letting you define materials individually.
