A crumpled Paper Bag

HornOxx

Hi All, here is a little model I want to share.
To create it I've used Julia Christina Eneroths "Fractal Terrain Eroder"-plugin and Tigs
"Quadrilateralizer"-plugin. Only the region where the logo texture is added, is edited by
Tig's "Quadrilateralizer"-plugin, which worked fine! This plugin changed the selected triangulated
faces into quads - so the logo texture could be applied. Thanks to both authors for sharing these
great tools! In the final render the area of the baguette is replaced by a matching photo of a
real baguette within Photoshop.

if you're interested, here is the model:

PS: the baguette in the bag I have borrowed from the 3D Warehouse.

Very nice! Well done!

Thanks for the process instructions as well.

Thank you for using a "used" paper bag
Novel modeling

Great. Now you can design like Gehry. How is the logo section added to the rest? Point by point? And why is that even necessary?

lovely!

thanks for your comments!

@ Bob: in this supermarket there are no plastic bags available at all

@ pbacot: I'm not doing a Gehry design - out of respect

"How is the logo section added to the rest? Point by point?"
I have selected this small area manually and then converted the selection into a group.
With rectangular(?) selection that worked very quickly.
Texturing just this group made it possible that the logo will not appear on the entire bag.
Since this logo area is a group, the group could remain in it´s original position. I have
moved forward this group, only in order to illustrate how I did it...

"And why is that even necessary?
Your question is justified! Somehow it did not succeed to project the texture onto the
triangulated faces - don´t know why. So I tried to use the quad-face method, which worked immediately.
Tig's plugin had only to convert a small piece of geometry, which accelerated the whole thing.

Thanks, I see. Very effective model.
