Hello,

I keep looking all around for tutorials on rocks/stones/outcroppings, but everything is either very bob ross like or just has you doing procedural displacements with limited control.

Does anyone know of any tutorials that have shed any insight for them into creating rock structures? For the piece I'm working on I want something that is fairly realistic- but stylized, and would like to have more control over their shape etc.

Any reference would be helpful- 3D, painting, drawing - anything.

I'm just running into that issue with the net where there are hundreds of "tips and tutorials" on a subject...but almost all of them are...kind of...worthless for what I need.

I know that "rocks" are actually one of the harder things to believably create from scratch, and like clouds they look very different from one another and at different times of day- so I'm not looking for a godsend, just something to get me headed in the right direction!

Thank You,
Gideon

Well this is the first thing I thought of.. 12$

That's almost enough, but I'm already kind of "OK" with creating that sort of look:

Thank you though- I know I'm being really vague.

I'll try and look up some images of what I'm after- that should help.

Nice bird and hand sculpts by the way!

Do you have any particular type of rock or environment in mind?

probably bryce is the simplest, then export the mesh

Small question: Have you try to use DF Sculpt plug-in with noise options? For example to sphere or sub-patched cube with several segments. I tried when have trial lw

OK, so here is the crux of the problem and why, at least at the moment (maybe all the time), I'm an idiot. Sorry to waste everyones time!

I'm still searching on the net for something to show- but it would kind of be like some of the better back drop stone work done in anime with a bit of elements like these:

I think I'm just either going to have to create it by "hand" using zbrush or 3DC alpha, or with a lot of nodes being driven by maps as I also need to maybe have a path in it and a fair amount of control over the shapes...was looking for an "easier" out, but I'm afraid it doesn't exist (funny how that works in 3D eh?).

Right now I just need to experiment and keep looking for what I need- I'm going to just have to emulate and see if I can get close to what is in my head...this is worse than working with clouds and trying to describe them in words!

I'll post when and if I've found what I'm looking for with an image or two!

Do you have a link to this by any chance? I'm trying to find it on the net and having a hard time for some reason.

What's the matter with just doing it in Layout with various shaped subpatch objects and procedural displacements?

blender has a sculpt tool. and it can also bake out normal maps. slight learning curve and time investment, but hey it's free :).

You seem to have 3D coat, why not use the Voxel sculpting tool and convert that to polygons?

Daniele made wonder to lw!

DF_Sculpt_Tool
Version
1.1
Language
C
Requirements
Lightwave 8.5
Description
This modeling plug can modify object geometry by moving its points on their normals or using a bulging effect. It was developed mainly for landscapes creation and organic deformation. My first plug in C. :)
Focus
The algorithm will evaluate points of a mesh and it checks if they are inside the deformation spheres defined by handles, interpolations and frequency. In the sphere session the plug will find the intersection of the normal with the spheres.

If you have 3DCoat I would use that, fast and easy with full control.

Yeah I don't have a problem caused by not having a given software tool set (XSI, LW, 3D Coat, Zbrush). It's more an...execution, methodology type of thing when it comes to approaching various kinds of rock in many forms.

For instance I've found helpful tutorials about the different kinds of clouds and how to think/look at them in a constructive manner, but nothing for rocks/stones yet that goes beyond either copying from life or just making something that generically says "rock".

I think I'm just going to have to do some old fashioned experimentation and observation to get close to what I want. Thank you though for all the suggestions thus far- and again I'm sorry that I asked the question in such a vague way and without having references yet!

Ask Pavlov, he has done this before. I think he had photos of the existing cliffs to work with.

http://video.google.it/videoplay?docid=-3372968041179160437

click the small google button and select original dimensions if it opens too big and fuzzy.

I remember images in these posts but they seem to be missing now. These are from 2006.

Those were some very nice cliffs indeed!

I guess until I'm more experienced I'm going to have to go with using photo references and kind of patch work my idea together. Have to run before you can fly eh?

Do you have 3D Coat or ZBrush? They're great for landscapes. It's easy to create displacement and / or normal maps directly from rock textures. You can also add procedural bumps in Lightwave. My animation thread below has a few examples :)
