Simulink video viewer black screen

Hi all,

The video viewer does not show output of the vehicle camera in the simulation. The environment is based on unreal engine 4.23 and the output warning shown is

Warning: The block 'Simulation 3D Camera' returned no data (error code: -1). Make sure that the block sample time is greater than the Simulation 3D Scene Configuration block sample time. > In sim3d/CameraReader/read In sim3d/AbstractCameraSensor/read In sim3d/CameraVisionSensor/read In Simulation3DCamera/stepImpl

Although the camera viewer sample time is greater than the 3D scene it throws the same error.

Looking forward to your response

Hi Mayuresh! What are the sample times that you are using for both the viewer and the 3D scene configuration block? Can you attach your model here so that we can take a look?

This issue may arise if all the Sim3D blocks are not in the same subsystem. Place all the blocks in the same subsystem if possible, then update the execution order. See more information here.
