Saving after opening it gets rid of the errors, but when I attempt to render it or add lighting to the preview the virtual memory blows out to 1.7Gb in a matter of seconds and TG crashes :( The only change I made was replacing the image map with a fractal


That may be due to a bug that has been fixed in the alpha version that Frank is using. That fix will be in this month's public update. There are some shaders that can't be used as part of a displacement calculation, and you may need to isolate those shaders until you discover which is to blame. Unfortunately I can't remember which shaders they are.

Just because milk is white doesn't mean that clouds are made of milk.

Just to let you know that Frank and I are still on (y)our way.

This is a function that still needs some tuning ...

This is looking really good Volker!  Finally, those voronoi straight lines are becoming broken up a bit.  Nice work!   8)

I'd be more help, but I'm busy learning other stuff.  Sometime next week I'll get back into TG2 learning mode.  As usual, I expect to need to run for a couple of weeks before I even catch a sniff of trails like this one.

This looks nice, Volker.  Really good.

@nvseal: Nope.  :'(

But attached is the improved and cleaned version  ;D

After importing the Clip, you should check the internal network of 'Voroni Cracks'.

It has again a group of modificators.
Patch size, Constant vector ('Same as Patch size') and the scale of the Powerfractal should have approximate values.

Have fun ... and watch for updates,

Volker

Thanks, Volker.  You're a good educator.   ;D

Thanks, looks really useful, but I don't get how to plug it in. When I view the group there are no node junctions and when I view the internal network I cant access the nodes from the rest of the scene ???
I know I'm missing something but I cant seem to find it.

Hi Richard,

this is my way to keep a scene setup clean ,-)
Look here for an example: http://forums.planetside.co.uk/index.php?topic=1909.0

If you want to use the cracks as a child of a surface shader, then right-click that little triangle on top of that shader which is for the child-input.
A little menu appears, choose asign shader --> VoroniCracks/Output

Got it?

Volker :)

Volker, I can't get this TGC to open.  I'm getting a couple of errors about intersection something or other.
