Hiya, im trying to import a lidar scan then drive a vehicle around on it but the car keeps flipping, getting stuck and not moving at all. Could someone help me understand what i can change to make it smooth?
Thanks
Hi Rob, Welcome to the Forums.
My first thought was “You can’t drive cars around on a lidar scan - lidar just imports a cloud of points with location and color!” (No physicality or collision on the points)
But I’m guessing you’ve generated a mesh from the point cloud?
The first thing I’d look at is the collision geometry.
This is from this scan: Collective Spaces Land, low resolution model - Download Free 3D model by JoeAgnew [ec81182] - Sketchfab - I’m unsure exactly how this model was created though. (Probably more photogrammetry based than lidar based)
Then I think the second step would be trying to fine-tune the lidar to mesh export settings. Maybe if the point cloud can be thinned out (less dense) the geometry will be smoother?
Hiya, i have managed to sort the collisions so that i can shoot balls from guns and they bounce of the lidar scans and also so that people can jump around within the point cloud, but sadly when i try with a car it just flips about and stops all the time. I feel like i want it to stay on the road but not worry about every single point. Thanks for the reply
Are you using the sports car from the vehicle template? My first guess would be that the collision on that car is low to the ground and getting hung-up on spiky geometry. - There’s also an ‘offroad vehicle’ in the same template that’s worth trying.
Glad to hear you’re able to walk around on it with a character though, the character (specifically, the ‘Character Movement Component’ inside of the Character) has a “Max Step Height” variable that allows it to walk up stairs etc. - So that might be why you’re seeing be more easily walkable with a Character.
