Road Surface Appears Gray and Hazy After Importing from MATLAB RoadRunner

carla-dev ubuntu 20.04

Description of the Issue: After importing the road created using MATLAB RoadRunner into CARLA, the road surface appears to be gray and hazy. I'm not sure if this is a rendering issue.

Steps to Reproduce:

Create a road model using MATLAB RoadRunner. Export the created road model in a format compatible with CARLA. Load the exported road model into CARLA. Observe the display of the road surface. Expected Behavior: The road surface should appear clear and as expected from the creation.

Actual Behavior: The road surface appears gray and hazy, lacking clarity, and it's uncertain if this is a rendering issue.

Hi, with a flat surface it worked for me, but after changing the Z value of some polygons I got a similar effect.

Shadows are darker at some places and around the Z value changes it has a weird texture. It could happen with a flat surface, too, but I can't confirm if it does.

It is only a guess, but I believe it is not only the RoadRunner texture with this behavior. The pictures are from a custom map we created for our project.

Thanks. Did you figure out how to solve this problem, and make it look normal?

Hi, I didn't fix it, but my guess is that it is an generated texture, and to have a good quality you have to create/use your own texture. Another problem could be, that UnrealEngine has a problem with shadows or the quality of the picture is too low.

Maybe someone with more experience with RoadRunner can answer that.

Sounds good, I'll try. Thanks a lot

hi! When I export the created road model in a CARLA compatible format, it shows the following road, am I missing that step? How can I export the same road model as you, and I look forward to your reply

Hi, did you Import the .xodr + .fbx with this steps? https://carla.readthedocs.io/en/0.9.15/tuto_M_add_map_source/
