Hey everyone, I reached out to MrSilverLust as I had not heard from him in a while, nor seen a public post here or on the NIF discord since early August.
I was pleased to see a response only a few days later, in which he let me know that he is well and is working hard on adding content such as animations and some render improvements to create a more polished "v0.6.x" version that will become the Steam early access launch version. His silence was just due to the fact that he is keeping away from forums so he is not distracted too much
This is of course exactly what he said he was going to work on in an earlier post, so all of my worries turned out to be pointless.
Following the Steam early access release, he is planning to swing onto creating new content for V0.7.
