HtoA 1.0.0 RC2
5 September 2014
This is the second release candidate of HtoA 1.0, fixing a critical crashing bug in IPR and adds support for Windows and Mac.
This release uses Arnold 126.96.36.199 and OpenVDB 2.3.0.
Fixed random crashes when using IPR
IPR support for Windows and Mac
Linking with wrong libJPEG on OSX
Exception when ROP shutter length is zero
On Windows, tumbling the viewport camera with a render region disables IPR updates in the viewport for ever.
A workaround is to create a new Scene View tab and close any stuck Scene View. Another possible workaround is to hold down the mouse button when tumbling and wait for the render region update.
This bug is still under investigation. The Linux and Mac builds are unaffected.
