Wow I am not sure if I want to touch this one lol. Alright sorry I will play nice but you sound a bit like me mum who always wants to know how I create my images and then when I tell her, she just stares at me with a glazed look in her eyes.

I can't say this enough read, read, read. Read that manual forward and back. Then play play, play don't try to run when you have not learnt to walk.

So 1st off why do you want to remove the ground? Are you creating a space or air image? Tell me why you think you need to remove the ground then it is easy as clicking on that grid that is the ground plane. It should turn from grey to red then just click the delete key on your keyboard POOF its gone. Still wondering why you want to delete a perfectly good ground plane though LOL.

2nd The content that you downloaded is for Daz studio and needs to be installed there. This opens up and whole new can of worms as well as a sort of plug-in program to Bryce. Daz Studio allows you to move pose and shape figures. But again and I mean no offense here I think you are getting way ahead of yourself. If you do not know computers well and then this is your first 3D application you should fiddle with Bryce for a good long while then jump right into posing.

Again I tease but I mean well. If you have any other questions please ask but noodle with Bryce and read read read is my best advice right now.

Cheers.
