Create diamond texture - meetdilip - 06-26-2020
How can we create a Diamond texture like this ? I assume we have to use the Filter > Noise and then do something further. Any tips will be great.

My try
[attachment=4580]
(1) Filters -> Render -> Noise -> Simplex Noise large value and reduce the opacity
(2) Filters -> Generic -> Dilate to grow the lighter pixels
(3) Duplicate the layer for a bumpmap and Filters -> Blur -> Gaussian Blur with a small value say, 1
(4) Back to the base layer, Filters -> Map -> Bumpmap Use the bumpmap as Input and adjust to suit. Experiment with Modes, I used multiply.
If you want to apply that small vertical blur, chance to try the new Lens Blur filter
(5) New layer, Make a map. Black for no blur, White is very blurred so go black to gray.
(6) Filters -> Blur -> Lens Blur Use the blur map layer as input. Adjust to suit Again experiment with the mode.
Those steps all in one: https://i.imgur.com/edbHoHJ.jpg

Thanks. I am having trouble with step no. 5. Mainly because I do not know how to create a 3 step blend. I know only with 2 points. FG and BG.

Very much in the eye of the beholder
For a very regular effect use the gradient tool in bilinear mode https://i.imgur.com/P51vlsE.jpg
I wanted something a bit irregular so painted in black over a grey base with a fuzzy brush then gave that a good Gaussian blur. https://i.imgur.com/0eb4tUE.jpg Then used in Focus blur.
As it happened I was not very happy with that, backed off (ctrl-z is your friend) painted in a bit more black, bit more blur and Focus blur again. Pays to experiment.

I give up. No matter what I do, I am not getting that glitter effect in the diamond pattern. Maybe I will try when I feel less exhausted.
Many thanks for your help.

Someone will come along with a better method.
When you come back to it. Maybe give the result a sharpen. The image you posted looks like it might have that.
RE: Create diamond texture - meetdilip - 06-26-2020
Thanks. I am unable to locate the " Sharpen " option though.
Update :
Found it. Mistook it for the resynthesiser option.
I tried again. Any tips on 2 types of grain ?
1. White and big, bright
2. grey, fine and small
RE: Create diamond texture - rich2005 - 06-26-2020
I was thinking of the regular Unsharp mask `Edit -> Enhance -> Sharpen (Unsharp Mask)
Gimp has a filter search option - the forward slash /? question mark key Type in a search term and see what is available.
That might harden up those white pixels but 'sparkle' is difficult with a bitmap editor, usually needs a bit of movement (animation or video).
