Hello, all.

I was off work today with a bad back - and ended up doing this little
monster whilst teaching myself how to model with blobs.

BTW -Technical query here.  The rear view of the bot is a cheat.  I had to
comment out the code for the image maps (that's the stylised robot head on
the chest and the number 23 on the shoulder) as they were being 'projected
through' to the back.  Anyone know a way to get them onto the front only,
without having to split the object down the middle and union the two
different versions (one with maps, one without) back together?  Badly
phrased, but I hope someone understands what I mean.

And, nearly forgot...  Thanks Rune for your blob tutorial!  I understand
negative strength a lot more now.

Bye,
Alan.

One way would be to use a gradient pigment_map to restrict the 
image_mapped portion to the front.

pigment_map {gradient Dir
    [0 ImageMapPigment]
    [0 ImageMapPigment]
    [0 NoImageMapPigment]
    [0 NoImageMapPigment]
}

Or do something similar using layered textures to layer the image_map on 
the base texture. That could be more difficult, though...

If you aren't committed to using an image_map, and are using MegaPOV, 
those designs should be fairly easy to duplicate with the object pattern.

Q- "Anyone know a way to get them onto the front only"

A?- "Use the text object and merge it with a copy of the chest creating a
new object. increase the scale a little and place it back in the scene...
Hope that helps."

Did same thing for train cars.
Make a gradient with an abrupt change halfway between the two sides.

Hello,

Since nobody else used the word "great" to describe Allan's blob bot,
I'LL DO IT!  I really like the smooth edges of blobs. But so far, blobs
are not very controlable to me. This blob-bot is great work.

Thanks, Hugo.  (I've sent you the scene-file to have a look at.)

As mentioned in the post, you might like to have a look at Rune's Blob
Tutorial - it really helped me to understand how they work:

http://rsj.mobilixnet.dk/3d/blobs/blobs.html

And thanks to Chris, David and CJ for the help with the image maps - problem
solved using a gradient -z and a pigment map.

See ya,
Alan.

PS - For those of us who read Robert Rankin novels, doesn't it strike you as
odd that I mentioned 'Hugo Rune' in this message?
