I tried using Surface Spread a few hundred trees but the export process was too long and I stopped. SurfaceSpred probably is not the best solution with Indigo.

perhaps you should set 'current state to object'

[zeitmeister]

Surface Spread, MoGraph and Forester are not the best solution for scattering large amounts of instances, because they "listen" to an editor-/scene-refresh permanently.
It's the same problem like the Cindigo Material preview with using large textures; Cinema tries to refresh permanently.
Only Carbonscatter doesn't so! It generates all full instances only at render time, which means at export, so that the c4d Editor window doesn't do anything.
For large, performant amounts of instances imho CS is the only solution for C4D.
Though it's very bitchy sometimes.

Vue d'esprit and Bryce?

... and how would you export them to Indigo?

The first step of experiments with C4D + Surface SPREAD; 1000 cubes, material FSS.

Thank you Zeitmeister. Your explanation is exact.
Arc en ciel, could you please post an example of material scattering with cubes instead of trees? I'm not able to get it working...

I like your image , very sweet, wonderful.
is the moon 3d object ?

Arc en ciel, could you please post an example of material scattering

i'll post something in "into the wild's thread" soon

Edit : when you 'll copy paste scatter code in your igs from C4D, you need to change the scatter's uid
I recommand to paste the scatter code at the end of the file and according the precedent objet's uid, change it

Code: Select all

  <scatter>
		<uid>change this number according your sequence</uid>

the scatter's name in UI

Code: Select all

<name>

you can run many prototype's objects

<proto_object_groups>

each one reference to mesh uid
exemple : you want scatter a tree named "myTree", search "myTree" in igs file, you'll find a model2 tag, this tag reference to a mesh, use this (uid) mesh reference in scatter's proto

Code: Select all

<proto_object_group>
				<geometry_uid>13052</geometry_uid>

from the model2 tag "myTree", copy paste materials reference in proto

Code: Select all

				<materials>
					<material_uid>8</material_uid>
          <material_uid>9</material_uid>
          <material_uid>10</material_uid>
				</materials>

and off course you need to reference the target's object, in this case it is the model2's uid asked

Code: Select all

<target_object_uid>12</target_object_uid>

the tag about material target is not recordable

Hi arc en ciel.
Thank you. The moon is at real scale trough atmosphere.

This is the procedure I follow more or less for the scatter. I´m waiting for some info on how to use the material slot. I´m not able to do it work. Also seems that the IGS or PIGS don´t save the info about this slot. The other day you post here an example that seems to work, but don´t worry, I´ll wait for some Ono´s example.
Thank you again.

[OnoSendai]

Here's an example.

[yonosoy]

Sorry Ono. I had express myself in a bad way.
Of course it works when a simple material is selected, but don´t works at the moment when the material is part of a blended one. The goal is to instance over the soil but not over the rock, two materials of the same slope blended material. Hope that it works in the future and so many thanks for your time.

[OnoSendai]

Ok.
Probably the best way to do that is with a shader.
You can define evalCreate() to not create the object (return false) when the slope is too high.

[yonosoy]

I understand Ono, but with my few words of ISL is out of my actual possibilities (for much more over).

169 k samples/s, 2000 samples per pixel in 5 hours. 26 millions of instances. If I instanciated the back patch the igs file has over 2 gigas of space; in this case I can´t open the file to scatter the grass and the bushes.
Anybody knows about a XML editor capable of that?

Really beautiful image !

[yonosoy]

Thanks arc en ciel, but vim don´t open a 4 gb file . Obviusly the way is to proceed with the internal indigo´s scatter.

Some drama in earth simulation.
