I have this group input that generates a "lens flare":

Node Tree

I would like to know if it is possible to 'parent' the location of the flare to the sphere at the bottom of the image. I do not want to use any scripts [yet]. Any help would be appreciated. :)


My menu options:


Blender Render vs. Cycles [Help!]

While you don't want to use scripts, I think you will have to use a driver to achieve what you want. Drivers can be a lot simpler than python scripts.

I'm thinking you want to alter the X value of the translate node. With your cursor over the X value, either press D or right click and select Add Driver, the value will then be highlighted in purple. The driver details are available in the graph editor, change F-Curve to Drivers in the graph editor header and select the value on the left, press N to show the properties panel on the right.

enter image description here

In this example the variable is named getVal and it will be equal to the X location of the object called Sphere. The scripted expression is set to getVal * 10, which means the X value of the translate node will be set to the Sphere's X location times 10.


Not sure if its what your looking for but the [Input > Object Info] node allows access to the vector location of the object in the current context...

from there basic maths should magic you up some results

best of luck =)

Here are some links to some decent youtube channels that have helped me learn cycles




and of coarse blender.stackexchange is here for specific quesions
