Thanks for the file.
You're not seeing the image because RailClone has exceeded one or more of it's limits. You'll find these in the Display rollout.
However, instead of increasing these limits, I'd recommend optimising the style so that as much of it is instanced as possible. To do this it's helpful to understand when a segment is converted to non- instanced geometry, basically there are two rules:
- Geometry is instanced as long as it is not deformed
- Geometry is instanced as long as it is not sliced
Because the curves in your hedge are over a very large area, I think you'll be able to turn off bend without seeing any visible problems and thus maintain instancing, saving loads of memory. If we turn off slicing too, we get a highly optimised and low memory style. To do this.
1. Select the hedge segment, go to the properties and turn off Bend
2. Go to the Generator's Properties and change the Default Mode
I've attached a version of your file with those changes.
I hope that helps, please let me know if you have any further questions.
