hey,
I ran into a bug while working.
Here are the steps,
Made a image map of a river and imported as a tiff.
Copied a PF build by DandelO

Used the Image map to displace the terrain and got the river shape cut into the planet as expected.
Then I pasted the DandelO in and connected to the input of the image map, and copied the image map as a mask to the PF and inverted it.
The result is what I wanted in the first place. But when I deleted the PF mask, then the PF vanished in the 3D preview.
And no mater what I did or how I connected the PF again, it would not show up in the preview.
I hope you can reproduce this on your own. But if not I will make a screen vid But I would prefer not to have to take the time.
I think I need to revert my copy of TG to the last version?
OSX 10.10.1
Here is a screen grab, you can clearly see the PF is attached and not working now at all. Also, a copy of the set up in tgd. I opened several times to see if it would fix it self somehow, but it wont.
This is all to do with this thread:
http://www.planetside.co.uk/forums/index.php/topic,19310.15.html I thought I was getting dumb because I could not make it work, though it should have been very simple. Glad it is a bug and not me!!
Thanks for reading
