Hi all people of elysiun. Can anyone tell me how to write an expression for something in Blender. Is there any documentation on writing expressions anywhere. Is there a way of setting up a custom slider panel for your facial shapes or creating a slider box that drives expressions linked to parameters or other object values etc.
Does anyone know what I’m talking about?
Thanx
You want the RVK sliders, which are in the NLA window. First you have to set your RVKs though,…IamInnocent left a good tutorial on RVKs in news and chat forum, and Luckybreak left another good one here in General forum, so do a search for RVK by those 2 authors, and have a ball. It takes a little learning, but they are good tuts.
Currently the closest you can get to expressions is by writing python scripts. You can link scripts to objects, or to update when the frame changes, etc. I hope more progress will be made in this area in the future.
Thanx Modron, that was really helpful, and I will definitely be able to use those sliders for facial, is there a way to build your own sliderbox as a “custom parameter” on a “per object” basis, and e.g. assign a button that brings up that sliderbox when hit?
Thanx broken, when you say :“You can link scripts to objects, or to update when the frame changes, etc.” are there any tuts on how to do those two things you just mentioned? They will help me achieve the desired results.
Also, is can you use a python script to build a UI sliderbox in Blender?
If so does anyone know where I can find a “how to”?
Thanx
All your questions have been discussed here for years and you really need to do a search (of this site).
Look at the scripts and blends on this site as a starter:

All of them are for earlier versions of blender but the basics are relevant enough to bring you up to speed.
