Hi all ...
I am trying to create a series of boulders I can drop into models.
My skills are poor as most of the modeling I do is rectangular forms.
I tired loft and network and got nowhere so I started with a sphere and cut flat planes with boolean ... so far so good but I tried to fillet most of the edges and it seemed to work (some surplus artifacts needed to be deleted) but while lines appeared indicating that fillets had happened the edges still appear to be sharp.
Stuck ..
thanks
eric

A good reason to use the subdiv function! ;)

A simple cube trimed : export as obj then apply the new SUBdiv from a file function of the beta V 4 ;)

You will obtain a lovely polished stone!



or with the old Subdiv by Max SMirnov



but careful with the old Max you can't make this following! (with the new function integrated of the betaV4 yes! ;)

Hi eric!

First thought in my head is that Zbrush would be a better tool for that, even if you want a very stylized result.

Now, for your specific situation, there are instances where fillet and chamfer will not complete successfully because of the specific geometry of your object. For example, for a fillet command to completely process a series of edges, it needs to have the necessary distance from nearby edges to create the circular profile. From my understanding (I am new to MoI) as things get more cluttered and geometry becomes more complicated, completing fillets on a whole object or even a series of edges becomes more difficult. Sometimes, merging edges (using the merge command) and picking small groups, or even selecting a specific surface might give you a better chance. When the fillet command fails to process your selection it sometimes creates a profile that with slight modifications can be booleaned or used as a trimming object so you can get something close to what you were going for. That's what you are seeing in your example.

Subdiv will work also with your start object but as it's not very adapted result will be not very suitable! :)
Depend of what do you want exactly and size of what is viewed! :)



With this yellow stone (yours subdivided post 1)

About fillets you will have any problem to make them if you export in Step format to the free DesignSpark Mechanical ;)

Even with your "special" object! ;)



But it's a little tricky ;)
See my French site about that! ;)

Hi eric, you might try some of these models with the new SubD importer:

Hi,

What you could do is use the push/pull method.

Make a

- Sphere
- show points
- select different points and then push and pull them around to get a form that you prefer.
- if you need more variation you can then cut into those stones - boolean
- chamfer if needed.

For uvmapping you probably want to use tri-planar method in your chosen engine as there are no UV's. With a detailed height/displacement map to show details.


I have also added some Sub-D stones in the file. They took me a 5 mintues to create using procedurals as apposed to manual sculpting.
