Help With Rendering

when u cut out a render,how do u make it transparant on the forum to just have the render,like this one i rendered

u can see white around it

 

Wrong place to post this...

But to answer your question...you save the render as .PNG

 

so like this

but then how do u add like ur rendered by ur name thing

 

Just add a new text layer and write it in there...
