In the first 3 or 4 updates, there was a serious configuration issue with the Dev's Daz3D. Also, the skin of that particular character, and the MC, react horribly to light levels, even to light directions.
Later, the configuration issue was solved and things started to go much better. It is now solved, not only because of the things getting fixed, but also, better hardware, more experience and several drivers and software updates.
We tend to forget that all this has a learning curve, when Tropecita started MyDorm, he was completely new to all this. But, he's been working on it almost daily, for 2 years, he has improved tremendously, in all aspects.
So, relax, grind your teeth and keep going, it will soon be MUCH better.
Peace
