building roads - mesh decals

[han]

Hi, I have created road models in fbx file format. Created mesh decals and apply the model. So I have a complete set of roads.

My problem is, how to make vehicles to follow the path of the roads? I tried to export path from blender but failed.

Need suggestion for this. Anything that I missed?

Thank you

Hello Han,

Path files are  problematic to generate today because they can be extracted only from 3DS max 2017 and earlier versions. To make an object move along specified trajectory you have multiple options:

• Using tracker tool. No coding involved, only predefined movements possible.
• Writing logic with checkpoints, we used this approach in Oil Platform demo
• Writing logic with SplineGraph. Sample is available in the SDK (<UnigineSDK>/data/samples/worlds/spline_graph_00). In some cases it's better to write custom solution, like it was made here.

Thanks.
