MixCast SDK for Unreal - 2.0.1


Expanded Additive Blending Support

If your experience treats its final render as an additive layer regardless of the values your materials write to the alpha channel (ex: an AR experience), you can now enable the “Force Additive Blending” checkbox in your Project’s MixCast settings to have MixCast blend the digital foreground with the physical scene using additive blending (ignoring alpha) as well.

Expanded Actor Visibility Control

The MixCast SDK for Unreal now provides more control over which actors are rendered to the user’s view and to the MixCast cameras. Since MixCast Cameras can take a number of forms (first-person/third-person, virtual/mixed reality, etc), additional filtering is offered for even more specificity. Check out the documentation page on this feature for more details!

Improvements & Fixes
  • Ensuring compatibility with Unreal 4.23/4.24 and packaging new builds for all versions (4.17-4.24).
  • Improving SDK logic when running both Server and Client in Unreal Editor.

MixCast Moments Support

Your experience can now send events to and receive commands from the MixCast Client to power advanced recording functionality and tailor experiences for demonstration or location-based usage. Contact us if you’re interested in learning more about MixCast Moments!
