Hello everybody.

Hope you can help me. Gimpchat doesn't let me insert pics, videos as I'm a new member. When you google Constantin Film intro and click pictures or video, thats what I'm trying to achieve.

The question is only about those sunrays. They seem to have some sort of semiround structure.

Is it possible to achieve this effect? I'm playing around for a week or so but nothing seems to work. I've tried all sorts of gradients, g'mic and filters.

Is that effect just achieved by the semitransparent sunburst with supernova when it overlaps the other sun?

Or do I need to add some texture to the sunrays?

Or can somebody point me some tools I should experiment with.

Any suggestions are welcome and thank you all for your valuable input.

Olleho

Here is a screen shot on how to find some sun rays tutorials.
Click search, type in sunrays, then click text tutorials, and there are several to choose from.

A simple way to do this can be done using a "Line Nova".
Image
By playing with the values in the line nova dialog, you can create this effect.
Make note of the "offset radius" in the dialog. A "0" offset radius will start the line nova in the center of you canvas.
Image
The color of the line nova is determined by what your FG color is. Mine was left as default (Black).
Any other effect would have to be created by you, in whichever way you see fit.
If you're will to wait. I'm working on a "Sun Ray" brush, which should be completed soon. ;)

Thank you Wallace. I've got now something like this:

Image

Got some sort of structure now, but its edgy and not in the middle. Any thoughts on how to make the structure rounder it and make it the same in every single ray?

Looks like you didn't make note of the "offset radius". If it is set to "0", the line nova will start in the center of your canvas. I also used a number that can be divided evenly by 4 to get the number of lines in the "line nova", to be somewhat even on my canvas.
However, I did make some "Sun Burst" brushes that you can try out to see if they will work for you.

Thank you soo much Wallace, for the work you did.
The second brush looks like what I'm after. How did you achieve that highlight effect?

I've got this now:

Image

Created a multiple radient gradient, applied it on canvas from the middle to top (conical), then with path selected a triangle in the middle, rescaled width, and then duplicating layer, rotation 180°, merge layers and then duplicating again, rotating 90° and so on...

Almost too rounded for me now. Guess a little darker red on top will do...

Run Line Nova on a transparent background, duplicate background.
Alpha select each layer, using Shaped (angular) gradients for their specific color combo.
Rotate the duplicate layer (10-12) to show between the original.
Crop excess while positioning the centre offset.

Example, 800x800 canvas.

I ran the line nova and then alpha selected it and shrunk the selection a little. Then added a lighter color to the selection on another layer. Then I Gaussian Blurred this layer. Then did another alpha to selection on the original layer. Inverted the selection, and used this inverted alpha selection to remove the excess from the layer above it with the lighter color. After merging the layers, I scaled it to slightly larger, and did a "layer to Image size".
That's what I did in this image below. Then lowered this layers opacity until it look good to me.
