I designed this bottle and its label in Rhino (i designed the label in illustrator and then brought it in Rhino as a material). As Rhino hadn’t .glb output format I had to transfer the objects into Blender.
Because the label position changed in Blender, I had to transfer the object parts with two different formats. I imported the body and label as one united object with .obj format ( to prevent the label replacement), and the other parts as a few separate objects with .fbx format into Blender.
Well, this method worked.
The employer requested a .glb output file, and I did that for him.
After this stage, the employer asked me later, can you reduce the numbers of polys in Blender ( that is one of my questions). I don’t know how to do that in Blender and how to create a low poly object?
I opened the saved and closed Blender file later but encountered an odd thing:
The label had been deleted, while it existed before I save and close Blender! (as you see in the picture)
Why this happen, and how can I recover the label( that is my second question)?
Most likely, the image file has been moved. To fix this, navigate to the image texture node, click the folder, and select the image texture to load it.
Another possibility is that the texture is an SVG file, and you need to convert it to a raster image to use it as an image texture node. This can be quickly done by importing the image to gimp, and exporting it to a JPG or PNG.
Ok here’s something you can try- select everything below the neck/top of the bottle, since that part needs to keep its shape. Add that to a vertex group. Set that vertex group in your decimate modifier, and click the arrow button next to the group name to invert it
First, go to the triangle-looking icon in the properties. Then, open up the Vertex Groups panel. Click the “+” to add a new group. Select what you want, click “Assign” to add to that group
Something must have gone wrong in the process. If you Assigned your vertices to the group you’d be seeing something like this where part of the mesh maintains the original geometry and part does not:
