Hi, everyone! I am trying to import a RoadRunner map I created in RoadRunner with sofar no success. Has anyone followed this process through on Linux successfully? Please, asking for advice, dead in the water until I can resolve this… help is greatly appreciated! Also, I’m not a content developer or scene modeler, so this is new to me. I have created a map in Roadrunner with a simple road network, no traffic signals, and a lot of props (scenery, mostly trees, rocks, and traffic barriers). The map has the following properties: 1) It follows an elevation contour from the GIS database that includes hills and smooth areas, 2) the road network is simple, with an circle around the perimeter, perpendicular roads crossing through the center, with each quadrant having 1-3 winding roads within it, 3) different rural forest scenery in each quadrant. Q1 is is an open field with a lot of bushes and some rocks. Q2 is an open field with sparse pine trees. Q3 is a dense pine forest with dirt roads, and Q4 is a dense hardwood forest with dirt roads.
The roads contain some hazards, such as branches, rocks, fallen trees, and highway barriers. I only used Roadrunner props. As you can imagine, this map has a lot of props (each tree, rock, etc is a prop). I am trying to import this map to Carla running Ubuntu 18.04, GeForce RTX 2070 NVIDIA, 64 GB RAM, 2TB i7-1075H (6 cores) and Carla 0.9.11. This is a sufficiently powered machine, according to the information in the docs and in forums. Sofar, no success. The package import process described and recommended in the Carla manual utterly failed. Not only could I not import my map, but the import scripts CORRUPTED the package installation such that I could no longer load any of the maps that came with Carla and had to re-install the Carla package installation. Fail. I attempted the method recommended by RoadRunner (the plugins), got a source build of Carla, and attempted to use the plugins. The plugin appeared to start to import my map, and then the entire process appeared to hang. I left it running all night, with no success. I cut out half the map to try to simplify things a bit (only 2 quadrants), and left it to load all night. No success. (attempted to load this image, but I was only allowed to include one picture in this post)
I then tried to use the plugin import process to import the extremely simple FourWaySignal (a road intersection with a traffic light, no props/scenery) map that came with Carla. Can’t get much simpler than that, and this is a map that came with RoadRunner; I didn’t create it. (I wanted to include this picture, but the system would only let me include 1 picture in the post)
This process took about 5 minutes. Why does a simple intersection with no scenery take 5 minutes to import? This shouldn’t be the case. I then added some trees and rocks to the FourWaySignal scene. Not too many.
(It would have been really helpful to be able to include a second picture here, but the system would only let me include 1 picture in this post).
That map import took a full 36 minutes to import. Such a simple scene should not take 36 minutes to import. To emphasize the simplicity of this map - it contained only an intersection, a traffic light, and a few trees and rocks. It wasn’t complicated. The trees and rocks added to the scene increased the load time by 30+ minutes. Why? If this scene won’t load efficiently, no way will my map load. I then took a simplified version of my map, just a quadrant, left it to import all night, and no success (no errors reported, either). I contacted MathWorks, and they were able to load my full map on a Windows platform, although they say it took 5 hours+ to do so. That tells me that nothing is wrong with the map itself. But why should the import process take this long, even on Windows? I do not have a Windows box, btw. Can this be fixed??? Are there some settings in Linux which would accelerate the loading process? Dead in the water, if I can’t import. The remaining options seem to be 1) manual import, 2) use RoadRunner to import OpenDrive map, develop scenery in Unreal. I am not convinced that the manual import process is going to go much faster, if the RoadRunner plugin is a thin wrapper on top of this. If the import process truly doesn’t work very well, and the solution is to develop the scenery in Unreal, that should be stated up-front in both the Carla and the RoadRunner documentation as a limitation so that we don’t end up wasting time (and this has taken a LOT of time). If the answer is that I should use something other than RoadRunner to create content, it would be helpful to know that as well. Thanks so much for any advice!
