I broke SU - shape study.

I was about to post this in the SketchUp forum, maybe even in the bugs forum but got a result I believe is worthy of posting here. So here is the rendering and below is my original topic of how I broke SketchUp

Twilight Render, hdr lighting, simple tone mapping, exposure 2, gamma .8, High+ preset, 2min 30s render time.

%(#408000)[Ok, so I was playing around with shapes and came up with something interesting (to me anyway). So I wanted to do a rendering with hdr lighting and shoot it overnight. The problem is I cannot add a texture to the shape.

I built it by placing some random points in 3d space then used the F-spline script to trace a path. I then used the pipe along path script to make it a cylinder. I stretched and squished until I had something more interesting then I used Subdivide and Smooth. After a couple iterations I had this smooth shape that weighed in at just over 30,000 faces at a size of 4.64 MB. Not too heavy for a model but very heavy for a component or group.

So, I decided to set up the scene by giving this thing a material, this is where I realized I broke SU (not really just this file I guess). Every time I try to give the surface a texture SU shuts down, no bugsplat, no warning just 'poof', gone. So I tried exploding the component and SU just locks up. No activity at all. Of course if I leave it for a few hours it might finish exploding but I want to go to bed.

I was able to paint the group without editing so I may just get a render out of it after all.
Anyway, I just thought I would share. ]

That's quite freak, Eric, but at least the render is cool and it was well worth posting it here!

If you tweak it a little bit so it vaguely resembles a letter, this weird shape would make a cool logo.

yeah boo I cannot explode organic forms sometimes too, it just freezes.

love the render mate....very natural and soft lighting. great caustic too well done.

lovely shape and lovely colour!

ah i see you got down with the tone mapping....simple always looks good for these refractive materials; there seems to be more colour

I always use components (models imported from blender) 10 000 to 60 000 faces. I can have four or five individual huge components or groups. To explode them was never a problem. It takes some (5) min though. I think its all about topology... where blender just rocks. Because its completely wrong to subdivide triangulated meshes. Not to handle quads, its a major problem of SU. Just activate 'show hidden geo', try to move a point and see the whole truth behind this handy GUI.

Very cool geometric volume!
Maybe this site can interest you
And this program given here yesterday

Forgot to comment this.
Beautiful, I agree with Miguel, it could be a great logo too.
A logo for a better zbrush maybe. If it was a Z(b)

Great shape - looks amazing in that material.

Thanks for the kind comments all. I appreciate it.

Here is another, as well as a small tutorial on how I made the shape. In the tut I did not subdivide the model, I will leave that to you if you wish. The file went from 117kb to 4.64MB after subdividing with 3 iterations.

Edit: Uploaded version 6 of the tut.
