Hi Noobee
Take a look at your forum messages....
As a beta process the current Reloaded still has a lot missing, but there is enough there to develop cool environments, and even basic shooter games. Characters are a bit of a sticky subject, since the Reloaded system supports characters with a specific structure and a specific set of animations. As such the creation of your own characters has some limitations. If you look through these forums you'll find a lot of information on the current state of the subject.
As for additional Characters, there is a way to convert FPS Classic characters so they work in Reloaded. This requires the purchase of the the Animer software from The Game Creator Store. Classic Package #4 has a set of general (non-military) charatcers which can be converted.
As for external systems like Blender, Blender is great but difficult to learn because it is so feature rich. There have been some (myself not included) who have been successful in porting Blender meshes and textures to Reloaded, but it's not easy. I have been using a program called MilkShape, whose direct X export works perfectly with Reloaded. Also, MilkShape can import files and textures from many different formats and convert them to a Direct X file that can be used in Reloaded. MilkShape is not great for Character development, but works well for other entities (buildings, etc.) and can incorporate animations that work in Reloaded.
Hope this helps
