I have created a system of entirely procedurally generated flowers which involves a spaghetti of groups within groups and instances within instances.

The part that I am having trouble with is controlling the open and closed state using a value, which can be driven by a proximity object.

Is it possible to control values of individual instances?

Edit:

I'm basically trying to change a value within an instanced node group from 0.000 - 1.000 based on it's proximity to an empty or geometry. I'm not trying to change the instance transforms within the instance on points node itself.

Many thanks!

  • $\begingroup$ Not quite, that question is relation to transforms to the instances. What I'm asking about is changing values within a node group that is being instanced. $\endgroup$

    $\begingroup$ Oh, then I think it's not possible in version 3.0. But I believe you can do it with version 3.1 alpha $\endgroup$

Since Blender's Geometry Nodes doesn't have loops for now, you cannot make a flower 100 times in a row. Also, you cannot modify the flower after it was instanced, because it will be very tricky in your case. So I suggest the following:

Instead of making the flower and when distribute it on surface, do the opposite thing: distribute the root thing on the surface and then add flowers and leafs on every root thing at the same time

  • $\begingroup$ Thanks, this sounds promising. It will take a moment to 'invert' the node tree but I will give it a go. $\endgroup$

Since you didn't provide a blend file (and even no screenshot with your proximity) so we can check it out...of course you can control individual instances. Here is the basic setup and how it works:

if you want help with your setup, provide your blend file.
