Is modifying World Position Offset affects collision & normals of a static mesh ?

Hi,

I want to modify the x,y and z position of vertices of a grid ( plane ) mesh. I came across the fact that it can be easily done by using WorldPositionOffset node in materials. Now my question is that does this modification I desire affect the collision data too ?
The main point is that I want a plane which dynamically moves upward and downward and player still stand on it. for this I assume the collision data should wave the same way as the surface is waving

second question : does it affect the normal maps(vertices of mesh). because I have a static mesh, and then the issue is that by changing the position of the vertices I actually should change the value of normal maps too. how can this be done ?

No, the collision will stay the way the original mesh was.
It wont be affected by worldpos.

Normal maps, if done right should stay just the same :slight_smile:

can you describe me more about if done right part ?
