Does anyone know if it is possible to recreate an object using blenders geometry nodes in c4d?  As an example I have an asteroid created by displacing a cube using geomerty nodes. (Ok just my idea of what an asteriod *might* look like :D ).  I tried to recreate it using scene nodes but failed….  I’ll attach the .blend file to this in case someone wants to take a peek.

Hi charles.horan,

Sorry, I do not have Blender installed.
Anyway, that shouldn’t be a problem, as what you like to do is undoubtedly communicate-able in a visual way.
Do you have an image of what you would like to do?

Besides, have you explored this series?

Hi charles.horan,

Hehe, sorry about the homework: No input, no output!

I guess the suggested series doesn’t provide you with the parts you need here. So take the night off. wink

Here is a simple setup. Just a sphere and displacement. You certainly need more details and a different Noise. (etc.)
I hope that is a good pointer.

P.S.: I couldn’t resist to use a render based option as well.

Very odd, when I open up the node version There is a group (Group1) when I click into that it is empty.

Hi charles.horan,

Sorry about that.

Please check this file.

Please notice that the resolution is relatively low, but it shows how it works. I’m sure you have a concrete idea of how to mix the noises.

Cheers

After workign through the Noseman’s at your example (very similiar to one of the samples from the tutorial) I came up with a slight hybrid that I think expresses what I am trying to do a bit better.

I’m attaching two files roid4.c4d and roid6.c4d in case they may help anyone else with similiar issues.  While I managed to generate a reasonable asteroid from the scene nodes(roid4.c4d) I was unable to apply a redshift material to the generated geometry as such I ended up exporting it as a fbx and then reimporting the fbx(roid6.c4d) to which I could finally apply a material.  The workflow currently seems very cumbersome and ‘pre-alpha’ to me…which doesn’t mean much as I’m not an expert :D

Hi charles.horan,

To my understanding, the Scene Node system (modeling) is more of a public beta; it is not even promoted as fully integrated.

Which is I think it is obvious because nothing shows up in the Object Manager. However, I see that I have the need to stress this point.

If you have any concerns or functionality requests, please voice your ideas here:

Support ticket> Suggestions.

All the best

No need to stress the point.  I’ve been a developer for 30+ years I fully understand the need for tech previews.  This one shows promise but it is simply not ready for wide release at this point in time.

To be fair, I’m more impressed that it is a point of being almost usefull than I am disappointed in missing features.

Thanks for the feedback, charles.horan.
.
I write in a forum, which means writing to a broad audience.
I do not evaluate anyone or judge here. I have replied to an uncountable number of people for nearly two decades, and I often have zero ideas about their backgrounds.

I often click on the public profile here to gain some insight, to answer in the best way possible. Usually, I do not even find an URL entry in the profile.


If you write something - I will reply. Please understand that it addresses you and tries to give a readable reply even to a starter (if possible).

Since you have a lot of experience, I hope you put some ideas into the Support> suggestions. grin
Thanks for considering!


Have a wonderful weekend

My experience has been writing business applications.  I have effectively no experience with 3D or with 3D workflows, a fact that I try to keep forefront in my mind before offering opinions :D

From my perspective offering opinions when I don’t know what I don’t know..would be an act of hubris. 

There are workflows in c4d that have been so well executed that I didn’t even notice them.  A good example is the continuity of selections and polygon numbering.  Until I took a dip into scene nodes I was entirely unaware of the underlying workflow.  IMHO that is the sign of well thought out and well executed software, it gets out of the way.  Until I gain some actual expertise I think I’m best to stick to learning and trust to a proven team to continue to deliver well thought out and well executed workflows.
