What's the issue you encountered?

I want to set the material of a StaticMeshActor named Bennu by using the API SimSetObjectMaterial() and simSetObjectMaterialFromTexture(). The code is provided as follows:

client = airsim.MultirotorClient()
client.confirmConnection()
# get control
client.reset()
client.enableApiControl(True)
# unlock
client.armDisarm(True)

# get target information
target_name = "Bennu"
target = Target(client, target_name=target_name)
print('=> Target name: {} \n=> Target pose: {} \n=> Target size: {}'.format(target.name, target.pose, target.size))
client.simSetObjectMaterialFromTexture(object_name=target_name, texture_path="./sample_texture.jpg")
# client.simSetObjectMaterial(target_name, "Black_Plastic")

However, both two API do not work and report following errors (ps: the 'sample_texture.jpg' file is added in my python project directory):

Traceback (most recent call last):
  File "E:/Program/airsim_rc_test/remote_control.py", line 198, in <module>
    client.simSetObjectMaterialFromTexture(target_name, "sample_texture.jpg")
  File "D:\Anaconda\envs\airsim\lib\site-packages\airsim\client.py", line 217, in simSetObjectMaterialFromTexture
    return self.client.call("simSetObjectMaterialFromTexture", object_name, texture_path)
  File "D:\Anaconda\envs\airsim\lib\site-packages\msgpackrpc\session.py", line 41, in call
    return self.send_request(method, args).get()
  File "D:\Anaconda\envs\airsim\lib\site-packages\msgpackrpc\future.py", line 45, in get
    raise error.RPCError(self._error)

Same problem here. Just found out that the problem is that the PyPI version of the AirSim is 1.7.0. In the 1.8.1 they added a new parameter for both simSetObjectMaterial and simSetObjectMaterialFromTexture. You can build the python library yourself and then it should work.

@Dongzhou-1996 just update the package, it should work now.
