Twinmotion line artifacts in glass

[padraigmcalister]

Hey guys,

 

Not sure if this is the right place to post but I've got a question about some artifacts I'm getting in glass reflections in Twinmnotion 2018 as seen below:

 

 

I originally thought it was something to do with my graphics card as it is a 780 however as I checked on the tutorials on the twinmotion youtube channel, they have the same problems and I'm assuming they run on much better machines.

 

FYI: I am away from my own PC today so the above image is from one of the Twinmotion 2018 tutorials i was talking about.
