Hi there!
I'm having trouble setting up a light in Gazebo. I tried with sunlight, directional light and spot light, and the results of each of those are quite similar, something like this.
I don't know what am I doing wrong, but I tried on another computer with the same settings and they work properly.
I'm using Ubuntu 16.04 LTS with ROS Kinetic
Greetings.
I've seen this happening with every graphics card except nvidia.
You are right. I wonder why this error still happens and it has been lasted half a year.
Could you tell me if you have fixed it out on an Intel GPU's PC?
I can't duplicate the problem here. I got my employer to give me sudo for switching graphics adapters so I was able to try my laptop's Intel graphics. A basic gazebo .world with a "sun" light works for me on Intel. I'm using Gazebo 9.8.0-1~bionic on Ubuntu 18.04.
Here's the same issue on bitbucket. Maybe if it gets more votes we would manage to draw some attention to the problem. https://bitbucket.org/osrf/gazebo/iss...
I have an onboard Intel GPU and have the same problem. Like Louise above suggested I run the setup.sh for Gazebo and have the GAZEBO_RESOURCE_PATH, GAZEBO_PLUGIN_PATH and GAZEBO_MODEL_PATH set. I also tried to compile Gazebo (but not all the dependencies) which did not change the rendering. Still some models are so dark that their details are not visible.
My workaround was to click on the World tab, then on Scene and finally deactivate shadows. If shadows is already deactivated, then toggle it.
An issue is still open on the repo.
Here are other related questions with the hope that the users would arrive on this page:
I had the same problem using Ubuntu 18.04 LTS with gazebo9.
My problem was related to BIOS secure boot which requires a particular driver installation procedure, as shown in this tutorial:
https://gist.github.com/bitsurgeon/b0...
I have not tried that procedure, but I simply disabled Secure Boot option in BIOS and reinstall the NVIDIA drivers and now gazebo works correctly.
I find that, if you compile gazebo yourself, then will not meet this problem.
Well I also use Intel GPU and install Gazebo from source but no luck. Object doesn't stop light so there is no shadow.
I hhave got the same problem with Ubuntu 18.04.01 + ROS Melodic. My solution is to switch the graphic card from Intel HD Graphics to Nvidia Quadro M1200 on my computer, the problem is sovled and now Gazebo functions normally.
Actually, I'm having the same problem. When the Intel graphic card is used Gazebo is not able to render the shadows, on the other hand, with an Nvidia card the issue disappears.
The worst thing is that gazebo is not returning any error or warning

Is there anyone that can explain to me why there is this problem?
I've seen this happening when Gazebo can't find some material resources it needs. Could you try sourcing the setup file before launching Gazebo?
You can find the file as follows:
find /usr -name setup.sh
Then source it like this for example:
. /usr/local/share/gazebo/setup.sh
No error whatsoever. I sourced the path like you said, and then ran Gazebo --verbose.

I had the same problem. I am using a laptop with dual graphics card (intel and nvidia) and running gazebo 11 on ubuntu 20.04.
Sun light had no effect, ground was dark and objects had no shadows.
When I was trying to figure if everything is alright with my graphics cards I found that the nvidia x server software is not detecting my nvidia card.
I then changed the nvidia driver from nvidia driver (open kernel), first option in the image below to the one currently selected in the same image, nvidia-driver-525 (proprietary)
I then rebooted my system and everything worked perfectly.
So it could be a driver issue and I hope anyone else still having the same problem will be able to solve it.
I'm having same problem with gazebo11 and ubuntu 18.04. However, when I upgrade to 20.04, the problem has disappeared for some reasons I'm not aware of. Unfortunately, I had to downgrade ubuntu because I'm using another device that is not compatible with 20.04. But at least, the graphics card wasn't the problem which in my case is amd graphics card.
I had same problem. I reinstall xorg software and it fix the problem with shadows in gazebo.
sudo apt-get install xserver-xorg-core
remove xorg-core hwe 18 automatically, but you can continue using your desktop environment. And later
sudo apt-get install xserver-xorg-core-hwe-18.04
sudo apt-get install xserver-xorg-input-all-hwe-18.04
I don't know why it's worked for me. Proofed in Ubuntu 18.04, gazebo 11.
