We are excited to have a guest tutorial by Greg Zaal from Blender Nerd for today’s tutorial.
In this Blender video tutorial I’ll show you how to make a realistic orange, cut in half. We’ll use three different methods to randomize the shape of the orange and move on to using Gimp to create all the different texture maps to create as much of a realistic material as we can. We’ll also make use of material nodes, texture painting and masks to make the transition between the skin and the cross-section less obvious


















What is the add hotkey you used at 44:41?
When Greg starts texturing painting at 18.08 his orange turns black and he’s able to paint. My orange never turns black and when I click and drag my brush over my orange, nothing happens, it doesn’t even move.
What’d I miss?
It sounds like you still need to apply a blank image to the UV maps; you can do this from the UV/Image editor by selecting all the UVs and then going to Image > New Image.

Thanks Jonathan, I hadn’t refreshed before replying so I didn’t see your reply.
Do you know of a good tutorial that really covers UV texturing, I seem to struggle in any tutorial that uses that technique.
Maybe this one will help: http://cgcookie.com/blender/2010/09/14/apple-texturing-part-2/
Ok, I am still a little confused here. I went into edit mode. I Created a UV mask, then hit CtrlU to unwrap the object. Fine so far. I hit A in the uv editor and all seems to be selected, then I select save as and save to an image. Finally, I go into texture paint mode, and like others have said, I get a white object and a circle for paint that will not move. So, how do you apply a blank image to the UVmaps to make this work right?
Thanks
p.s. other than this problem, this is a great tutorial and the problem is not with the tutorial, just my application of the principles.
Hi Gary,
Have you first created an image before/after unwrapping the UVs? The UVs do not inherently create an image. You must go to Image > New and then you should be able to paint.
Cheers,
Jonathan
Figured it out. You have to select all (by pressing ‘a’ in the mask. I also didn’t have color, specular or anything checked under material mapping (I think it was material mapping). I think Blender was trying to tell me, that I didn’t have anything selected to paint, and didn’t know what to paint on the nothing I had selected.
in mine too, but still is saved
where I think the texture of orange peel
Nice Tut.
Very informative, I’m now tempted to give compositing a try.
Sorry I cant seem to follow through the whole tutorial, I got problems when it comes to the orange material and I found already 3 textures in there and this is giving me some problems image is not aligned properly.
I like your tutorial’s
and thats my results

got a glitch jaja bad rendering! oouh…
what should I do to fix it?
Great Tutorial!
Any helpful suggestions?
unfortunately i couldnt figured out what happened with mine during painting the orange black and white. Mine turned white instead of black and it wouldnt paint anything.
hi Greg, thanks alot for this amazing tutorial. but i have two problems. first one is that when i added a defocus node and put the fstop on 20, the whole scene got blured, not like yours which only the surrounds got blured in yours. and second issue is that when i render it finally the sky didnt appear. can you pleaze help me in these errors.
thanks
Really great tutorial. I really enjoyed doing it.
What really would interest me now, is how to setup these materials in Cycles. I tried but didn’t get it to work.
Thanks for the tut.
When I try to look at the texture ( it’s around the 32 min in the tutorial) by pressing alt – z my orange does not show anything it just turns white. I just cant seem to figure it out why, could anyone help me with this ?
forgot to mention that the texture does come up when i render.
Great tut!
Great work Greg.
I was doing so well… And then I got lost half way through texturing. 1am I guess that is a sign to go to bed.
So my render shows up in the background of my node editor… but when I render I get a black screen on my composite :/ Any idea why that might be happening.
Is the final node of your compositing network connected to the “Composite” node?

Great tut that 1 Greg! excellent results in a short time. Thank you.
Great tutorial I learned alot. Thanks Greg
where do you get the textures?
