FAILSAFE!!!! Creating Crash Resistant Nodegroups in Blender Geometry Nodes

Have you ever created a node group that crashed Blender by accident? Well with a couple extra nodes, you can add a failsafe to those settings that can cause you trouble. Especially when it is a combination of settings that can get out of hand! This is one method when just setting a max and min value on a node socket isn't quite enough.

Another approach is to use min/max nodes to limit a input or calculation result though this is more limited than your general approach 👍

[@JohnnyMatthews]

Yeah absolutely. There are lots of ways to accomplish this sort of task. But the key is to help your nodes not get to a state where they cause you trouble.

[@RazsterTW]

I knew there was a method I just haven't had time to sit and create it. Thank you so much for sharing this, so helpful!

[@JohnnyMatthews]

Glad it was helpful!

[@beddyboy]

Johnny you think of everything. Such a generous person.

[@JohnnyMatthews]

Hope you can use it to your benefit!

I wish blender had similar failsafe built-in especially geometry nodes. I once accidentally applied scale to a 2 square km plane while geonodes was distributing points at density of 100 every square metre. Issue is we have to know what quantity could blow up, which we often don’t as beginners or when working with large node trees.

[@JohnnyMatthews]

Yeah it takes some trial and error for sure.

[@salarycat]

Thanks Johnny. It would be nice if the density-based distribute points node had such a failsafe as well.

[@zboy303]

This is a very cool idea, Johnny. I'm crashing every couple of minutes with the new Distrubute Points in Volume node!

[@JohnnyMatthews]

Yeah after I crashed one node tree several times using the subdivisions on an icosphere, I realized I needed to figure something out.

[@JoaoMarcoCc]

Great, JM!

[@ginescap]

that was great it can save a lot of time and hassle, thanks Johnny :)

[@JohnnyMatthews]

You're welcome!

[@neilmarshall5087]

So passing the alert to the shader and switching out to a warning color would be a good idea. Well - not in this case, nothing to show color on. If only there was a dev who could whip up code to make the nodes start flashing as a warning.....

[@seesignal1709]

Sir, how can we make dialogue lip sync like sprite fright using geometry nodes????

[@burnaboyb8821]

that is the poka-yoke tool

[@joachimderavenbel212]

Thanks a lot! It sounds so logical and I used a lot of similar limits when writing text code but never thought of doing it in GN. I was looking for an "if...then" node and that's the switch! You woudn't know of a hidden "for each" node, would you?

[@JohnnyMatthews]

Not yet. I know some sort of looping will happen eventually.

[@jenovaizquierdo]

This is really awesome thank you for the tip, 😤😠😡🤬 this has happened to me in Geo Node.

[@JohnnyMatthews]

Trust me, there is definitely a reason I figured this out 😰😰😰

[@jenovaizquierdo]

@@JohnnyMatthews I know and I’m great full you did. I’m going to use this method. 🙏😁 thank you.

Visual scripting???? Wowwwww
