helo:)
I have a problem with one bootle. I still learn LW, so it is hard to do for me make thats bump like below.

I try ordinary bump, but.. its not work like i think. Maybe someone has the same problem and resolved them?

Help, please :)

It looks like those areas are deep enough that you might want to model them into the bottle. A bump map will never let you get the correct look. You might be able to use a displacement map but I think that would be more trouble than it's worth.

Those wireframes look like they came from a cad package. Could you get a 3d file from them?

Yes, You`re right, but it isnt so simply :) I have something lika 3dxml file, but i can`t convert them. I make a visualisations for company where I work. They order a design of this bootle in glass factory. The glass faktory (or PET factory - no matter) don`t want to give us a full model. Only pdf and this *.3dxml. So, I shout prepare my own model.
Displacement map, You said... I will try tomorrow.. But maybe someone else has a good idea? Maybe other way to prepare a bump map?

Bump will never go deep enough and will look bad. Use bump only for fine detail or very low detail (as in not heigh). You could model them but maybe a displacement would be faster.

Make a UV map for the bottle, make a map with the design shape. Add the map in the diplacement tab of the object panel (p). Because of the curvy lines you'd propably want to try a high displacement setting.

This tutorial (http://www.highend3d.com/maya/tutorials/modeling/polygon/322-3.html) is written for Maya but the approach can be used in LW; it ought to help you with this. :)

Wow .. talk about dead on. I wish I could find tutorials on for EXACTLY what I'm looking for. Pretty cool Weepul.

Hmm, looks easy. But please remember, that i`m still learn LW :) I`m not an experience user :) But we will see. Now i have two ways to do this. Thanks for help.
But the thread is still open!

Its me again. Its highly propably, that i made something wrong with displacement map because it looks bad.. first i made UV map, then i open tab with propertis of object (bootle-plastic) on the "deform" tab, and then i push "T" next to displacement map. I choose UV mapping, my new texture (leafs), and z as displacemet axis and rest as is. And... i made something strange :) Like wind. I try with Bump on the same tab and it isnt work.

And the other way is too difficult for me.. for now :) So, any other idea?

I tried other way, with tutorial from weepul (thx!), first part is easy, but I think, in LW we havent the same tool like bend in Maya. Ok, bend is exist, but not so advance like in Maya. I cant e... spin around shape of bootle, of top part of bootle polygons with leafs. Or Im wrong?

ok, I made it.. mayby not perfect, but look quite good. Only this edhe over leafs.
http://foto.maspex.com/foto/0_test/bootle2.jpg
and i have 2 questions: why this leafs looks so... bad if my bitmap looks great, and how can i erase this edge over this leafs.

I used "enable bump" on deform tab with 1mm. Without displacement map.
Of course, in texture editor bump is enable with uv map.

I was curious about this, managed to produce this with just the bend tool (plus twist for the top), similar to the steps in the tutorial.

It's more about playing with the settings, the axes can get confusing.

Remember you can also set the 'influence' of the bend with the right mouse click ..


Can you show what looks bad?

looks great! But how? ... i work with a tablet, and ussually used only one button... maybe there is a reason..

It's a bit hard to show this way, but the key is where you click (in this case, in the bottom right viewport, vertically in line with the bottom right corner od the geometry) ..

As with almost all LW commands, you can click where you want it to scale around or from etc. scale it arbitrarily, then click undo and it remembers that location in the 'N' panel shown.

You can then type the accurate number, in this case 180, then click activate, instead of trying to get it right by eye ..

Hi everyone:)
I still need a help with almoust the same case. I shoul prepare renders like this

http://www.bracki7.fm.interia.pl/LW/20090120rabarbar.jpg


This is only photo with rendered label. Now I shoul make a pure render - I mean the shape leafs should be modeled (?). Did You have any idea how?

You don't chose easy ones ;) ..

Are there 4 leaves in total? That will help ..

Now You have nice preview. File from ftp was a try to show You the same. Later I was change the source. Thats all. But the problem has remained unresolved. Any idea? If some - please here or skype me: bracki7

Yes, only four. What can helps?

Perhaps not the ideal process, but here's how I'd tackle it ..

Ie. get it right in 2d, then bend and bend.

The lwo. file has the steps.

Notice the distortion in the final product, you'll have to allow for that.

This was just a few minutes playing around, but I think you get the idea.

Points to remember:
- Keep to 3 and 4 point polies.
- Try not to let your polygons get too distorted - keep them proportional, or you'll get render issues later on.
- Avoid too many polies intersecting at one point .. that's what is meant by 'good poly flow' (that, and making a 'mesh' of quads instead of tris) - ie. there are a few ugly points in this model already ;)
- Stick to the grid! you can already see that the bottle gets 'pinched' below the leaves (in the sub-d version) where I shifted the mesh.


(ps.LW trial version? .. waiting for registration of new dongle :) )

Great!
It can be. Bent should works. But first, I must prepare somethink to bend. I mean how from this:

http://www.bracki7.fm.interia.pl/LW/leafs.jpg

make somethink like this:

:) I know, I need a lot more to learn...

ok, now I have this one:

http://www.bracki7.fm.interia.pl/LW/3.jpg

and I want to merge with this one

http://www.bracki7.fm.interia.pl/LW/4.jpg

I was try boolean and drill and did not works. Any idea how to make it?

maybe the way Jeffery goes in this video http://www.pixelandpoly.com/video012.html
could help you to see how could you tweak you mesh to put those 2 toghether.
Good Luck

Thanks a lot. Last advise (link with tutorial) was very helpful :) I made model like there and this is it:

And.. another problems:)
After F9 I saw somethink like this:

Do You have a good settings for plastic?
