Among Vaughanīs exceptional videos there should be one showing a dog in
a cube. If I remember right it was about scaling UV-maps. But I canīt find
it among films covering UV-maps: I have checked in the differerent listings
I have available and I have also googled, but I canīt find it anywhere.

Anybody knowing what I am talking about? Any name of the file or other
ways to find it?

I am regularly looking back to those videos but now I am lost in this case.

I agree, so far i've been getting away with just applying surface properties to put my textures on my models... but I know that very soon I won't be able to work with that "crutch".

It sounds like you're talking about keeping the proper proportions of your UV by adding a cube to your object. If it is there's no real need to watch the video.

Just make a perfect cube or square plane around your object. Then when you make your UV (assuming it's a planar map) your object will have the proper proportions because the UV will be using the box as well. From there delete your box. Now you can scale, rotate your object to fit the UV space.

Yeah, I would like to see if there are any clever ways to combine UV-maps from different sides.

What I am thinking of is to combine many UV-maps sidewise on a long object.
If it could be done safely with some cubes put wall to wall, without disturbance in
the total output. That could increase the resolution in a map on an long object.

If it's a cube you could do an atlas map.

If it's something more complicated just select the faces that you want to associate with a certain project type and add it to your existing UV.

For example let's say you have a cylinder.

You would select the sides and go to Make new UV. In this example name the UV "Cylinder" and set the projection to be cylindrical.

Now select just the caps and go to Make new UV but change the name drop down from Texture to "Cylinder" and set it to Planar.

Now you have one UV map but each part is using a different projection.

That was good on how to keep the proportions on the UV-map.
Most often they are distorted. Thank you probiner!

Yes, this one I have studied. Maybe it has replaced the one I am thinking of.
That one had a dog-object inside a cube, but I do not remember whether it
combined different projections of the UV-map or not.

William, as you may read this, I want to thank you so much for your work
on the great suite of film-tutorials. They have really been a great help to
me. Just now my favorite is the one on displacements with the cute little
lizard. I am trying to figure out how to combine different displacements on
a surface with a smooth transition in between them.

Thank you so much for a great contribution the LW-community!
