csv in python sdk

[malcriado3d]

Hi guys,

trying to figure out how to set keyframes in my script, lets say rot X , taking data from a csv row that has the time value and another row that has degree value. Any tips or ideas where i can look for?

thanks in advance!

A sample code "ExportScene01.py" below in the sdk would be helpful for you. As you can see it, there are also helpful comments what we have to do for creating animation.

Please see in detail a URL below.

    # add at least one AnimLayer to the AnimStack. And for the purpose of this example,
    # one layer is all we need.

For reading csv, there are a lot of artcles in websites. So a URL for instance would be helpful.

I hope this helps.
