Short description of error
If I have two layers with animated objects and only have one of the layers active while changing frame only the objects in that layer are animated. So if I switch to the other layer it will not have been updated with the new animations/transforms and instead looks exactly like it did before the frame change.
The workaround for this that I use is to just go up a frame quickly and then down again (with both layers selected), but this shouldn't be necessary and can in cases with heavy scenes be very slow. I make game models so this is a small annoyance that often occurs while exploding highpoly and lowpoly models that are supposed to match up.
I could see this being a performance enhancement as opposed to a bug, so you don't have to wait for the whole scene to update all objects before you can start working again. I just thought it might be best to report it and see anyway to be sure.
Exact steps for others to reproduce the error
Here's a simple blend-file that clearly demonstrates the problem:
The two models (suzanne and torus) are keyframed to lie on top of each other.
Instructions:
- Change the active frame to 10 (with only one layer selected).
- Select the other layer and you'll see that the models do not match up.
- Go up or down a frame (with both layers selected) to make the animations match.
