Cache Transform on Python ObjNode

[dedeks3000]

Hye everyone,

 

I created a simple Python OBJ Node that performs some matrix stuff with the worldTransformation of  another nodes.

I need to store some transform but just once (sort of rest position) and the SetCookTransform()  reevaluate each time the values

I can do that with a pose Chop or maybe through userdata.

How to do that ?

Thanks

I would suggest a callback button on your node. When the user clicks it, it reads the transform into a parameter that your node then cooks using it. If you can, an even better alternative is to use a second input as your rest.

I often use cachedUserData for such tasks. It's easy and you have flexible control over your cached data. But beware, if the only thing you need is get worldTransformation of one object, it may be faster to just get one, instead of writing to cache, checking if cache is valid and so on.

@edward : your solution is good : click to store data. @Stalkerx777 : for reusable tool , i think it's not a problem.

 

Thanks.
