Hi AlexMurphy001, Let me help you with this. Duplicate the LowresCar blueprint and rename it as per convenience, Replace the car meshes in the blueprint, save & exit. Duplicate CarAgent Data asset, replace the Low Res Template actor under Traffic vehicle visualisation with the duplicated car blueprint. Under Traffic Vehicle Simulation, replace the Physics Vehicle Template Actor with the respective car blueprint that came with the City Sample Vehicles pack. Save and exit. Under the details panel of Mass Spawner placed in the level, add a new element in the Entity Types under the spawn dropdown. There should be 2 elements under Enitity Types- index [0] and index [1]. Open the drop down menu of index [1], and select the newly made Data Asset of the second Vehicle as Entity Config. Specify the proportions of the number of this vehicle to all vehicles under this spawner. Save All & press Simulate.
If you’ve done all of this and the second vehicle still doesn’t spawn, check if Mass Traffic Vehicle Spawn Data Generator is correctly processing multiple entity types. Otherwise, try increasing the total traffic volume to see if the second vehicle appears.
