HITL Problem

Hello,

I am trying to use the HITL simulation using Gazebo and QGC, with the 1.8.2 version of px4, using px4_fmu-v3 default. The problem is that when I run gazebo Tools/sitl_gazebo/worlds/iris.world, the parser is unable to find the iris model.

I have followed the HITL [guide] (https://dev.px4.io/en/simulation/hitl.html) step by step and I tried with other firmware versions, but the result is the same. Also, i check that i have the STM32F427 ver 3 so I don’t have the flash problem.
