modular cliff sculpting tutorial/question

ahtiandr

Hi all. I have searched the forums and the web but I couldnt find anything useful which could help me with my issue.

So basically I need to make few tileable cliff sculpts with different dimentions.These sculpts should be tileable with each other from left and right side.

I think my method is too tedious and it could be awesome to know a better way of doing this.

here is my way of doing it:

First I sculpt bigger plane with wrap modifier. Then I export it and bake to the big lowpoly plane. Thats pretty staightforward.

Now I need to make another plane which is a bit shorter in one dimension and is tileable with this bigger plane and with itself. For this I remove some geometry from the center of the bigger plane. Then I move both parts of the bigger plane together(I do it in another 3d package because it is not possible to do it precisely in zbrush) and weld the with dynamesh. Now I fix the seam in the middle and bake this to the shorter plane

here some pics to help you understand it better

Could you reupload the images? ( They seem dead to me. )

Oh my bad. Accidentally moved them to different folder in dropbox. Now all should be back again

There are many ways to sculpt tiled cliffs.

You could easily adapt one of these to make half-width variations. Just make a displacement map of your finished sculpt, make a new half-width plane, then lay down the map using a mask so it only applies to one side.

The mask could be a gradient, or better yet, a nicely-painted form-hugging mask.

If I mask one side then it will tile only from one side. I need the short plane to tile from left and right with itself and with the big plane. Maybe I am mistaken but you describe the masking part a bit better please ?

Eric Chadwick

Mask the left and right sides, and lay down left and right sides of the original. Then touch up the middle as needed. You could even use parts of the original.

ahtiandr

thanks this actually helped but I did it a bit differently. I havent done any disp maps but just projected one side of the sculpt while other side was masked and then offset the sculpt and projected another side. I guess this is what you meant.

Here is the result

Excellent, looks good! The low-poly geometry could use more detail, but this is probably just a test mesh.

ahtiandr

yeah I will make low poly mesh a bit more detailed
