Maya – Using Multiple UV Sets

Software:
Maya 2018

Note:
This post isn’t about “tiled UVs” (“UDIM”), it’s about multiple UV sets (layouts).

Explanation:
Polygon mesh models can have multiple UV sets. this becomes useful when the UV layout that is optimal for a certain texture isn’t efficient for different texture (in the same material).
For example, we might have a model of furniture, or clothing, in which the UV layout that is best for the fabric weave pattern, isn’t the best for dirt and wear & tear, or stickers.
In such cases we can define different UV sets for the model, each suitable for a different texture.

In this example, having a separate UV Set for the logo texture allows placing it without affecting the checker texture that is displayed an all the surfaces:uvsets

To create multiple UV sets:

  1. In the UV editor view, from the UV Sets menu, select UV Set Editor to open the UV Set Editor:

  3. Close the UV Sets Editor.
    The UV Editor view  now displays the new UV Set that is empty, and UV creation and editing operations will now affect the new UV Set.
  4. To switch to edit a different UV Set, select it from the list at the bottom of the UV Sets menu:

To link a texture to a specific UV Set:

  1. Make sure the texture is connected to the material set for the model.
  2. Select the model.
  3. Open Windows > Relationship Editors > UV Linking > Texture-Centric:

Blender – assign different cameras to different view-ports

Software:
Blender 2.79

By default, the view-ports Camera view in Blender displays the view from the camera that is set as the scene’s Active Camera.
If you split the view and in the new view select a different camera and set it as the Active Camera, the view in other view-ports set to camera view will update to display the new Active camera.
In short, by default, it seems you can’t assign different camera views to different view-ports..

But you can…

You just have to unlock the wanted view-port from the scene’s Active Camera by de-activating this button:

When the Use the scene’s Active Camera and layers in this view button is de-activated, your allowed to set an Active Camera for the specific view-port without changing the scene’s Active Camera setting, therefore not affecting other view-ports displaying the camera view.

Blender – Select Pattern

Software:
Blender 2.79

Use the Select Pattern tool to select multiple objects with name similarities.

  1. In the 3D View in Object mode choose Select > Select Pattern…
  2. In the Select Pattern dialog, type a part of a name with an Asterisk to define wild cards.
    For example *car* will select all objects who’s names contain the string ‘car’,
    And car* will select all objects who’s names begin with the string ‘car’.

Set parameters for multiple objects in Blender

Software:
Blender 2.79

Method A:

1) Select multiple objects

2) Alt + Click wanted parameter and change it

 

Method B:

1) Select multiple objects

2) Set the wanted parameter

3) right click parameter and choose ‘Copy To Selected’
* Do the same for grouped parameters like vectors using ‘Copy All To Selected’
