Hi Rudy,In my case UE-45723 they have said Set “Use Mouse for Touch” to true,I have to turn off and i move my mouse over the button and click then the color will appear,but if i turn on it the color won’t appear.
In UE 4,15 my project settings >Input>Use Mouse for touch>ture but the colors works without any setting or issue i don’t understand why?
Is there anyway to make it work fine as well as UE 4.15 ?
Thanks!
