Still having trouble with the Lighting filter not showing anything avail in the Background most of the time so I cheat if I must: Use the Lighting filter for what I can and then on new image use the gradient as a top layer and use Overlay or one of the other Blend modes that work.

Thank you Pat.
In spite of having some problems with the filter, you got a beautiful result. Hopefully someone can help to solve that problem. :thumbsup:

I have a question about step 11 of the tutorial.
When doing the gradient is it over top of the gray scale image or do I create a new layer for the gradient ?

Tom, I had difficulty with the lighting filter because of the pickiness it has for placement of the gradient for the environment map. Here is OMG's advice from post #11.

Post#11 by oldmangrumpy » 1 week 6 days ago

Pat - in the tutorial I did warn about this filter playing up; it often does not recognize files that have been opened after it has been used. I find it frustrating. It also seems to want the environment map layer to be called 'background'.

My work around is to open my project file and create the bump maps I need and I put target environment map on the background layer. Then I open the Lighting Effects filter.

After that if I want to use a different gradient as an environment map, I create it also on that same background layer i.e. I overwrite the previous one.
I have also found that turning the Environment Map checkbox off then on again allows a different map to be used.


Hope this is helpful.

Pat - thanks for helping out.

Tom - the gradient in question goes over the initial Background Layer to cope with the quirks of this filter, which Pat and I have referenced above.

You are welcome, OMG and Tom. One of the reasons I love this forum is that we help each other to learn. There is always something to learn with GIMP!

Oh well, I've had to admit defeat on this one, I've tried every which way I can think of but the Environment map simply refuses to show any layer options. I tried the bump mapping work around suggested in a previous post. I'm now going to work on other images to see if I can get this option to work at all. (I know it will only work on RGB). Anyone with any further suggestions - I'm all ears.
EDIT - I used 3 layers - made the gradient the bottom layer, next pink and just a desaturated pattern on top - hey presto it worked (ain't called Gimp for nowt). Thanx a mill for a great tut OMG.

Yep, my environment map with the lighting filter will not 'handle' more than 3 layers.
