Blender Geometry Nodes

Hi everyone, I have been trying to improve myself on Grashopper and SubD workflow in Rhino 7. Meanwhile because I find Blender compact like all in one software I started learning Blender. For SubD design I felt like Blender is more effective but I haven’t tried geometry nodes in Blender yet. Is there anyone who tried geoemtry nodes and do you think it is comparative with Grashopper? What are you experiences can you explain briefly?

I tried them. I suppose the node approach makes is somewhat similar, but it is much more limited as it is only geometry related. The focus is more ‘in-place’ generation.

Very powerful though.

I found the lists a little different, but the most interesting thing about blender nodes is the way they access color gradients and such as math parameters…

But it does not have accuracy like grasshopper… yes nodes in blender use math, but the accuracy and scale are less accessible and more under the hood.

Thank you for your answer, what do you mean exactly by accuracy?

You can specify number, disance etc, bu then you have to access that spreadhseet like tab with the thousands of values. Stick to GH. Blender has its uses, LuxCoreRender is very good rendering plugin - free, and for a cost effective commercial solution, you could combine corona render with blender, and achieve top results without paying for 3dsmax.


Sorry for the IMHO comments, but mcneel could position itself a little better to integrate with Unreal Engine, particularly as Unreals PCG graphs are pretty awesome.


Let me see if I could get lucky here.

This node Map Range takes a min and a max from incoming data, but as far as I know, GN has no nodes like Bounds or Deconstruct Domain in GH. So how come one knows which number should be input there?

I know it is ridiculous. But trust me this is the last attempt I could make to understand this node from GH’s perspective.

Or… come on, wait a moment… does this node remap incoming data automatically so one never needs to know the bounds of the original data? Is that the reason?

Not sure how UE52 pertains to geometry nodes…

Interesting blender plugin


mhh can you post an example of this used in Blender? THANKS!

I didn’t use it yet, just stumbled upon it recently.
You can find resources like videos about it online afair.


Guys actually the issue that really bothers me is whether Blender approaches grashopper in parametric design. If it is approaching, do you think there is a possibility that grashopper will be out of date after a while and leave its place to blender?

I think it can happen :roll_eyes:

I’d have to see it to believe it. I have used blender. Its great, its free but Rhino is just more user friendly right now. Blenders interface is hell.

GH is massive. The amount of third party input cannot be understated.


What was your purpose for using Blender and for what workflows you chose Rhino and Blender separately?

As a modeller, no, because Blender is mesh based.
As a visualization tool, yes, Rhino will have zero chance in near future.
But… Rhino is developed as a modelling tool, so I guess that does not matter to the developers.

I hope Rhino develops a live time bridge between Rhino and Blender, like Rhino and Keyshot. So that one can Modelling in Rhino/GH and visualize it in Blender. No need to develop Rhino’s Cycles when you can use whole blender as a renderer.


What about Blender’s modeling skillset? As far as I used for example for SubD it’s much more better than Rhino in my opinion.

the precision value in decimal places, this is not just related to geometry nodes but this is a difference between any polygonal vs Nurbs modelling software as they are designed for different needs.
Also in general Grashopper node workflow is very mature due to its age and Blender node workflow needs stability improvement.
Apart from that blender community is very creative and i amazed by the procedural building, cloud, snow, hairs etc created by artist. but you will see grashopper artist create precise building with accurate modelling as the same design will be used for manufacturing as well.
Overall i will say if your purpose is animation and visualization then go for blender (it will improve day by day)
and if you want professional workflow to model precisely to use in manufacturing and construction then use grasopper.


I used blender for 3D sculpting. I use rhino for engineering, architecture, CAD etc.

I prefer NOMAD sculpt bc its a touch and pen interface and more fun. I prefer rhino for post processing and remeshing because I already own it and its great

I believe you need to know the original bounds. So you could feed a min max or domain into the original range values and then remap values could be 0 to 1 for instance. (equivalent of reparameterize in some cases)

Alternatively it would be similar to slide within range. Like if I had a 0 to 1 slider that I wanted to use to select an RGB value I could have the range input 0 To 1 and the remap 0 To 255.

And the clamp node prevents the value from going past the range min/max values.

If it’s unclamped and you input a value of 2 that would give you 510 in his example, whilst a clamped node should give you 255 max even with an input of 2
