Notice in the image above, the key selected has “Linear interpolation” applied, but looking at the bezier handles and curve, it clearly is not linear. In the image below, I selected “linear” for the previous key, and you can see post-key / out, it is linear, but pre-key / in, it is still “auto”. Is this a bug or is there a setting I missed? In 3DS Max for instance, when you right click on a key, you have options for both the IN and OUT interpolation of the key. Note, I’ve also played with “break” and “flatten/straighten tangents” to no avail.
I noticed Max Chen mentioned upcoming updates in the following question, I just wanted to tag this question along with it.
