Important

* Demolition-NGXCUDA.dll is now integrated into Notch blocks and standalone executables automatically. Therefore you do not need to copy this DLL onto media servers when using blocks with NVIDIA specfic nodes.

Important

* Changes to the way that the Imported 3D Scene node handles looping animation means that for existing projects, the Loop End parameter no longer has the correct value set to loop animation clips seamlessly.

0.9.23.121 – 17th June 2020
Important
* A bug has been fixed in the Colour Correction node which caused the application of the hue, saturation, contrast and brightness to be affected by the image's alpha channel. This could cause your existing projects to look different in this new version of Notch. Please check your projects.
* A bug has been fixed in the FBX importer. Previously, FBX files with no animation data would not load node transforms correctly resulting in objects being placed at the origin of the scene. Node transform data is now correctly loaded regardless, which could result in some meshes in existing projects not being in the same location as before. This affected objects exported from Blender in particular.
* Please update your Kinect 4 Azure device firmware! We now support Kinect Azure SDK 1.4.0.

0.9.23.59 – 22nd October 2019
Important
We have changed the internal time base for Notch projects to a higher granularity. This allows keys and time bars at all common frame rates (12, 15, 25, 30, 50, 60, 100 etc) to be represented accurately. (Previously only 25 and 50 fps were able to be stored accurately.)

This is fully backwards-compatible: projects or bins saved in previous versions of Notch will load and convert to the new timebase without issue. 

But it is NOT forwards-compatible: projects saved from 0.9.23 will not load properly in older versions of Notch.

32bit support is now deprecated in Builder, blocks & standalone. The vast majority of host applications / media servers support 64bit, but if yours doesn't 0.9.22 (32bit) is still available for download.
