Description Martin Nordholts 2006-10-19 16:43:12 UTC
Many Photoshop based tutorials uses Difference Clouds to achive a certain effect.

A difference cloud is a normal cloud rendered, but with the Difference layer mode applied.

A Filter -> Render -> Cloud -> Difference Clouds filter would make following Photoshop based tutorials easier.

Where is the difference to applying the Coulds to a temp layer with
difference mode and then merging down that layer?

And, in photoshop, where is the difference to rendering clouds on
the layer and then using "Fade" to change the mode to Difference?

There is no difference, the filter would be there only to improve workflow, since this particular operation is common in some image effect maneuvers.

I don't have Photoshop unfortunately, but I assume there is no difference.

Again, this filter will act like a convinient "shortcut".

Feel free to add a script then that does this. When you have such a script, feel free to reopen this bug report and propose it for inclusion.
Comment 4 Martin Nordholts 2006-10-20 09:02:19 UTC
Why are you marking this bug as RESOLVED? That makes the RFE invisible to people who are browsing the bugs normally.

When I have time I will try to fix a script that does this, but there might be someone else who is willing to do this, and we should keep this report open for those people.

This is a script which implements this, and it appears to work nice for me. I am not experienced in writing these scripts though, so there might be something I've forgotten, please let me know if this is the case.
