Interoperability with V4 Scene Elements 

 

This task shows you how to convert V4 scene elements (environments, cameras, lights and turntables) into V5 scene elements.
  A V4 Integration license is required to copy V4 scene elements.
Open the V4TEAPOT_AND_CAT.model document.
  1. Double-click "MASTER" to display the tree.

  2. Click the plus sign beside "IMDE2" to display the scene elements.

  3. Select the element you wish to copy. If you want to copy several elements, you can use the multiselection:

  4. Copy the element(s) by selecting Edit > Copy or by right-clicking and selecting Copy.

  5. Open a product, for example, select Start > Infrastructure > Photo Studio.

  6. Activate the root product or an already existing node then paste the new elements by selecting Edit > Paste or by right-clicking and selecting Paste. In our example, the copied elements are pasted in "Product2" window:

    Note: You might have to zoom out successively to see entirely the environment.

As you can see in the above pictures, the copied scene elements keep the same names as well as their parameter values in most cases. For instance, a V4 spot light is converted to a spot light in V5 with the same angle, intensity, attenuation angle ratio, etc.
However, there are slight discrepancies since V4 and V5 scene elements are not fully equivalent:

  • Lights: V4 target is different from V5 target (which is computed with the target point and the attenuation end)
  • Cameras: V5 cameras do not have any width and height as this is the case for V4 cameras
  • Environments: 3D textures applied onto V4 environment walls are not converted. Environments converted from V4 to V5 are always "bare"
    Moreover, as far as spherical environments are concerned, they are always converted to big size environments because V4 spherical environments are sizeless
  • Turntables: a turntable is always pasted with the V4 environment it is associated with since V4 turntables cannot be created on their own like in V5. In our example, you can see that Turntable 1 is associated with V4 Transparent Cubic Environment.
    Note also that the angle of a converted turntable is always equal to 360 degrees, whichever value in V4.
