Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Sequencer Curve Editor Only Applies Key Interpolation Post-Key / Out

alt text

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.

Hate to bump this, but even with the new 4.20 weighted tangents update, this is still an issue. If the previous key is set to linear, you don't even have access to a bezier handle for the key you want to adjust.

Yes it appears we only do linear interpolation if the previous key is set to linear, otherwise we just do bezier and don't take into account the linear tangent handle. Investigating a fix.
