How Do I Add A Logo To 3d Image?

[davijoman]

Hey this is my first post on this forum, I just started my 3D animation module of my Creative Multimedia course and my assignment is to make a short advertisement for a juice company. I have made a simple flask in Maya using just the EP Curve Tool and the revolve tool. I got the fruit company's logo off their website and want to add it to the side of the flask, is there anyway I could do this? I would also like it to extrude a bit.

Anyone?

You could UV map it and add the logo in photoshop.

Hey DavijoMan

So you have 2 options here...

1. Model the logo in 3D
2. Use the image as a texture.

I would suggest you convert your nurbs model into polys as UV mapping is easier that way, also you will most likely be using polys later when you get a job.

What version of maya are you running?

If I use tools here you dont know about try searching for them in the maya help files (most useful, just hit F1 and search the tool name)

So use the convert nurbs to polys tool 1st. You might need to experiment with this one, it may give not enough or to many polys.

Now you want to go into photoshop and look at the size of your image, i use jpeg for textures in maya but if you want to render later using mental ray then tiff is good. (esp for ray tracing)

For UV mapping, heres a trick I use to get my image the right ratio on a surface. Look at the pixel size of you image, suppose its 900 x 600, create a poly plane, go to the channels box on the right, you might be in attribute mode, if so hit "ctrl a".

Your poly plane should be called polyplane1

now your ready to make your shader, so open your hpershade and create a lambert (good for image textures)

once you have created your lambert, (should be called Lambert2)

1. Double click it (Lambert2)
2. Double click it again
3. Click the color swatch button

Now you'll get the "render node window" up, then double click "file"

Now Just browse to the location of your image, best place it in sourceimages folder of your project (flask) folder...

Now you simply drag and drop your lambert into your poly plane, middle mouse button drag while poly plane is selected.

So now you should have you image on a poly plane, you can freeze the transformations, go to modify > freeze transformations.

Now you can scale and rotate the image plane to the size you want it on your flask.

move your verts around to make a face that the right size for you image plane, now can snap it in and snap the verts of your flask to the edges of your plane, combine then and merge verts.

Note that I used this method to teach how to make an image plane as well, a good technique for modeling to a drawing or photo.

You could also just add the shader we made to the face or faces you want to it applied to.

But then you need more UV specific knowledge. Also this image plane method is a cheat trick because you made the poly plane the size of the pic so the UVs are ready by default.

Have fun
