In the next build there is a new Global Specular slider which will allow you to affect a global setting which applies to ALL specular, whether it is in entities, terrain, characters or other renderables. I have also added a 'specular' field to the FPE where you can force an override of the specular texture (or even entirely replace the _S texture file requirement) and simply specify: 0-no specular, 1-dull gloss, 2-average specular, 3-high gloss. Between these you should have the control you need to refine the specular effect in your game. When creating your own specular maps, it is recommended you keep the values quite low (between 32-64) if you want a subtle effect as anything hire comes across as plastic or super reflective. Not to be confused with metallic reflection effect which is something my brain is tinkering with as a possible implementation to improve visuals still further. Watch blog for more news on this!
