and another 
Destructible car glass or only glass? The problems with the shader are that one needs to change collisions (mainly simple). How can it be done? With Niagara? At least some basic overview for classic gamedev workflow - damage, different material on damaged edges + what should one avoid when optimizing?
whether fluids can affect game mechanisms - for example, when flooded, whether the player can detect how deep it is and how its movement can be affected - will there be a link to the character movement component? Or behavior of chaos car and water fluid?
Can liquids damage the object? I assume that if it is based on DF and there is no hit event. So how about it in BP?
And there is nice video with geometry scripting that you proppably know. Which reminds me procedural destruction using the texture pattern form Ranbow Six Siege. So. Is there any time estimate on the Geometry scripting feature at least to the beta phase? Or with Nanite?
