ok so i trying out photoshop and i dont know how to cut out renders from their background, can some1 help me please?[/i]

Filter -> Extract

 

 

 

 

 

 

 

fill in the edges of the render with the paintbrush and fill it in with the bucket tool when you're done and press ok

 

 

 

 

 

 

 

then use the history brush to touch up the edges

tyvm

Np, there are other methods, but this is one of the quickest and still gets good results
