Hi,

How to create light rays effect with GIMP? These rays are something like the rays reach the ground under the clouds, background light and that penetrate through the hole, ...

I had walked through the web for some guidance/tutorial for this, but not yet found. So I hope someone is here to help.

Thanks in advance.

Hi!

I played a little, and got something that, while not photorealistic, is beautifull :-)

1) Create a new scratch layer. Paint in it your hole dimensions. 2) Create another scratch layer, draw straight lines coming from the hole in the direction you want your rays - these should be almost parallel, spreading a bit to your taste. Draw these with the paintbrush (hold shift to draw straight lines), with varying brush widths and varying opacities,
3) Select script-fu -> shadow-> drop shadow on the layer with these lines - select the yellow as color, and a blur radius of about 30. (und unset the cursed "allow resizing" button) 4) turn off the view of both scratch layers, and fine tune your result varying opacity on the final layer.

If you want a photorealistic result - you will have to use POVray for that.

Regards,

It sounds like you're describing what is commonly known as "godbeams". John Woods has several very good Photoshop tutorials online - most can be easily adapted to The Gimp. Check out this link and look for the godbeams tutorial:
