Thanks to everyone...

Yes andybot, I used that method to make my renders (separate objects by a minimun distance) and it looks awesome; but someone ask me to render his model and when I opened the file I found in a wall make of brick, but it wasn't just a pulled rectangle with texture, it was a brick by brick wall literally, and he didn't use components :S... now the problem is solved...

About the bevel edges plugin I didn't know about it... so I will take a look, I appreciate the suggestion, thanks again.

Thanks, it's works... but I wonder if there's another way to do this directly with the v-ray to avoid the merge of the images in photoshop or another program...

Hello everybody!!...
When I render in V-ray, it doesn't show the edges, because they aren't photorealist or something like that I guess... but for example when I render two cubes who are together with the same texture the result is like one box with no divisions... so, how can I adjust the v-ray to render the edges?...

Thanks!!
