I actually use seams… I’ve been working on some packagings and I’ve got the “unfolded” of the print. I definitely had to learn how to do it.
My problem here wasn’t “how to unfold” but “how to make sure that unfolding I don’t create a sharp edge”.
I explain better. My problem is more related with the usage of the displacement. I created a round “cap” for the cylinder. I mark the seams of the circle at the top and then I unwrap it properly. In this way what I’ll achieve is 2 circles and a rectangular shape on the UV editor [very roughly explained]. Now… I need to apply a displacement map on the top in order to create the gap between each wooden board. I still have the “height” [what in the UV editor is a rectangle] of the cylinder. Of course here I cannot apply the displacement as the wooden boards in the texture are seen from the top and what I’d like to get is having the nice gaps not only on the circular top and bottom of my cylinder but also on the height [if it’s not clear I can make a scheme]. When I’ll apply the displacement the height of my cylinder will be “sharp”. Basically if from the top there is a gap from the side there won’t be. How can I avoid to see the perfect circular shape of the height of my cylinder over the displaced top?
As you can understand my question is not related to how to unwrap or mark the seems but on how to make sure that the side of my cylinder deforms following the deformation of the top.
If this isn’t already clear I can post some kind of examples.
I noticed that Paolo has created a junction between the top and the side. He basically created a circle of polygons that are at 45° [basically the top is a plane at 0° and the sides polygons of the cylinder are at 90° - hope this is clear too]. In this way, despite the texture is a little bit deformed on these 45° polygons still shows the gap the interests me so much.
I think that this should sort out the problem that basically was:
- How to avoid the displacement to be sucked to the centre of the circle [1° image I posted]. In that case concentric rings suck the image to the centre of the circle, while this new hybrid “square in the centre, circle on the edge” shape works perfectly [and can be subdivided too!]
- How to be able to distort not just the top but also the side of the cylinder [again vertical side… what in the UV editor is unwrapped as a rectangle]. If you see my example the deformation works perfectly but the side of the cylinder is still visible as if it’s surrounding the top. I also understand why you spoke so much about UV unwrap… but I didn’t unwrap from the top as I’m not able to do it properly… I did it because I was trying to avoid to have the “height” of my cylinder un displaced and visible over the displaced top.
I actually already read the tutorial you posted, even if I prefer video tutorials [they work better for myself]. Thanks anyway for the link but unfortunately that wasn’t my problem
Although… now that I did a trial with this I can probably use the same texture to displace also the side [height] of the cylinder. I just need to make sure that the gaps fit.
Thank you anyway guys… for what I needed I could just have used a plain… but I’d have never learnt how to sort out the problem!!! Forgive me if I’ve been to picky but seen that I had this question in my ,mind I just wanted to make sure to have understood everything perfectly!
Paolo, if you want to visit Bolzano I suggest you to go after summer… in summer is quite too warm… even if you are from Florence the other city in Italy together with Milan being the warmest in summer.
I live in Manchester so in this very period of my life I’m quite far from home… Bt I suggest you to visit also the places around such as Renon, il Colle, Castelfeder, etc. If you need advices feel free to write me!
