Animation and Motion

[Matt]

You can set it to Linear if you select "Rotate by" (the group), not the Y channel. That's what I meant in my last post by "whole parameter". The bug seems to be with the dropdown menu on individual channels, even though it correctly updates the graph. (You can have different modes on each channel but the dropdown says the wrong thing.)

Thanks. That seems to set right. But at the same time, what if you didn't want X, Y, or Z to be TCB, but linear? Imagine something already in motion and adding another axis of rotation. That's actually what I had in mind with a impact event, adding a new vector of rotation. I suppose just another transform shader, but it will be working over the last, and not part of it's calculation for rotation.

As I said, individual channels can be changed (and you saw that the graph changed), it's just that the dropdown isn't behaving correctly.

Interesting. My exports were still in TCB mode when I was having this issue, and that's what I was doing (by channel).

This is the latest test on channel Y. As soon as you close the window, and open it again, it's back to TCB. If you render, it renders in TCB. If you open the project, it's back in TCB, etc.

Also why cant it be set from the root to govern all animation points? That doesnt work either but allows me to set linear.

Sorry, I'm unable to reproduce this. I just tested it now on a translation parameter with only the Y channel animated. Selecting the Y channel and changing the mode to Linear resulted in the plotted graph visibly changing to linear. Then I stepped through the animation in the main windows and it showed my object moving on a linear path. I rendered a sequence and that also showed linear movement. The only bug I can find is in the dropdown widget - yes the dropdown shows mode as TCB, but everything in the scene is moving in Linear like I wanted.

By the way, you can use the 'D' key in the graph editor (while the graph has mouse focus) to fit the curve to the graph.

Gave it one last try, doing exactly as you described and finally got it working. Though I still thought that's exactly what I was doing in the gifs but kept getting a TCB output. Strange. Thanks for the help. Also that focus key is very helpful.
