Hello, does anyone know how can I change vehicle wheel/shape radius in blueprint?
This should be straight forward assuming you have a vehicle blueprint already.
In the content drawer , double click your vehicle blueprint and it should show in its own window with the blueprint editor.
Check my image below:
Click on the viewport tab as circled in blue (so you can see each component helping you make sure you select the correct wheel)
Locate the components view on the far left (circled in green)
Locate the Wheel(s) you wish to modify
Locate the static mesh on the right hand side and change if required to your new mesh (in red)
Change scale , rotation and location as per transform tools (in green)
Hope this helps
