Hello again !
Right now I'm asking a lot of questions, sorry if it's too much lol
I just imported a sphere on terragen, I put a power fractal shader and I modified the sphere, I have this:
[attach=1]
Can I export this object in OBJ. file or soemthing like that and import it into another project to use it as a population for example?
I don't think I can do it but if you have a way to do something like that, I'm interested.
Thank you.
And have a nice day, obviously ! 8)
You can't.

You can't.
And I guess I can't duplicate my object? Unless I create another one, with the same settings....
Well, you can make a population of the objects...

How ? I know how to use population but for the example, I added a sphere but I can't transform this sphere in " sphere population "... or I'm wrong ?
Or I import an obj in the form of a sphere and there I could modify it and use it as a population!
I tried to import obj and apply a power fractal shader ( Like I do on my first test, the first post in this thread ) and nothing is happen, I think I do something wrong.
Edit : Doesn't work either when I import rock, I don't know why.
You can duplicate the sphere in TG. Just highlight the node and push ctrl c and then ctrl v. Then u will have 2 spheres.

Nice ! Thank you and do you know why I can apply power fractal shader only on sphere ? When I try to add power fractal on cube or other objects, I have no results.
You can apply PF on a cube also. Make sure you create the PF from the Displacement shader menu.
Also when you choose the cube take the Displaceable cube from the menu. I think that works better.

It works on the cube! Thank you! Thank you! But not on an object that I imported myself
Technically it should but it depend the set up of the objects. Perhaps you can upload the object here so we can take a look.
The sphere and cube are displacable objects, like the planet of TG. So they can handle displacement by PF very well. Imported objects are not, and it depends on the number of polygons whether you can displace well enough. Also, imported objects (with a lot of polys) that need to be displaced need to have 'force displacement' checked, or it'll be just bump.
Displacable objects can not (yet) be populated.
If you want to make a population of an imported object, you have to add a new population and choose your object as principal object. But as said, that can't be really displaced unless it's very high-poly.

Thanks for this data. Good to know this for sure!
You didn't? I thought you'd know.

Well I knew some part of it but was not fully sure how an imported object would react.
Not really saving the object, but you can use Ctrl-C and then in a 2nd instance of TG, do the Ctrl-V. I just tried the displaceable cube but suspect it would work on the other non-savable objects.
An idea, if you want to save several of these type of objects, make a TG and add each one. Then you will at least have one source to grab them later.
If you apply Displacement to a non-displaceable object, like an imported (external) object, it will not show up in the 3D view, and in order for it to render properly you need to change its rendering method in the object's Rendering tab to "Force Displacement". Results can be difficult to adjust and depend very much on object geometry density. Be sure to use very small values for displacement at first, and increase in small increments, or you will likely "explode" your object's geometry.

If you are starting with the native sphere object, you can always save the modified object as a clip file that can then be imported into other scenes. But I don't think you can use this to create a population.
If you start with an imported sphere mesh, then you have a couple of options:
- Connect your displacement PF to the imported object's Mesh Displacer slot and save the two nodes as a clip file. These can be imported into other scenes and plugged into population networks. "Ray trace objects" must be enabled. Also, the Displacement tab of the PF controls your displacement here.
- Make your displacement PF part of the object's internal shading network. Connect it to the Displacement input of the network's default shader. The Color tab of the PF controls the displacement, and "Ray trace objects" should be disabled, or (instead) select "Force displacement" in the object's render tab. Now, you can select the object node and export it as a TGO that can be imported into other scenes.
As mentioned earlier here, a high-poly smooth mesh works best.
Here's a good discussion of using displacements on imported objects. It includes links to more threads:
