[Help] Radial noise/alpha texture?

Recommended Posts

I'm looking to create an effect similar to the one below in my game (the screen effect, the blue lines/waves/thingy :P):

and for that I'm looking for a texture that is like that; that is, a white-black texture in polar coordinates (or at least looks like it), from the center to the outer edges.

I tried to use some effects like twist and render rays together with render clouds, but I can't seem to get it;

 

Anyone got any ideas how to make something similar to it?

Wow what you got there look great!

 

I downloaded the brush factory plugin with the brush pack, but honestly I'm not really sure how to use it.

That is, I can paint the smoke brushes, but I'm not sure how I want to paint it so I can apply the zoom blur so it would look like your result.

 

Any chance you can show a video of how you painted the smoke brushes? or explain it in hopefully way I'll understand?

Yeah I can do that for you.  Unfortunately it can't be right now, but I'll get it done in the next few hours if that's any help

I'll be waiting for it, thanks!

 

Hope you weren't holding your breath... you'll have turned blue ...

i missed the part where you wanted Black & White ... you can substitute the brush colour for white ... or do as I did use colour and the make B & W

If it's too 'dull' when B & W, duplicate that layer and set Blend Mode to Screen.  It brightens it considerably

Things to consider:

Brush factory has a maximum brush size of 500, so Rotate/Zoom to increase it is a work around on larger canvases. 

The less Zoom Blur given - the more definition is left of the original brush. 

In the video I made one brush stamp, and then duplicated the layer and rotated them.  You can use the built in rotation tool in Brush Factory

Experiment and use different brushes on different layers ... and different Zoom Blur settings on each layer.  You can get some nice results

 

I hope that helps in some way

Oh man wow! so much effort and it looks amazing and now I can easily follow - thank you so much!!

 

"Hope you weren't holding your breath" (I don't know how to quote) - not at all!

 

And thanks for the explanation as well - I love to learn so it's more than helpful :)

 

p.s.

My brush factory has a size limit of 1000. I'm guessing you're not updated or something :P

Nah I hadn't ... my bad ... thanks for pointing that out.  

 

You're welcome.   It really was no trouble, glad it helps.  Have fun experimenting

 

Totally unrelated - but to quote ... highlight text and a quote selection box pops up

Cool that's good to know - thanks!

 

p.s.

Is there a way to apply black as transparency to another layer?

 

That is, I got something like this so far (still playing though):

 

I got to this so far

Notice how the background is black and the smokes are white, so the texture can easily be made transparent/white.

However I'm not sure how to do the same with the black hole in the middle. I know I can just remove a circle from the smoke layer, but it won't have the same effect since we've done a blur to it

You could use an ellipse selection on the black and then run BoltBait's Transparency plugin to suit

Nice effect BTW ... better than my example

 

Edit ... alternatively use the eraser larger than the black/hardness about 10% and one click to erase where you want the transparency

I think your was better btw, but thanks ^^

 

The eraser method worked, awesome :D

 

Just wondering about the first method though: I tried using the ellipse selection (I can just select the entire area with magic wand on the black circle layer no?) and then use transparency, but it's the same transparency for the entire area right? or am I missing something

 

 

Also, is there a cool trick to make it somewhat seamless? I tried to use the 2 plugins I'm aware of, but the best result I got simply looks like the same image we got reduced by 0.25, multiplied 4 times and put into each corner.

 

If it helps, The middle isn't as important (since it's gonna be black/transparent anyway as you can see in the original picture)

 

p.s.

Just to explain the bigger picture, I'm trying to make something like the original picture, but where the "lines moves" (towards the center) in a repeatable way (inside the game engine, not as part of the texture). I'm not entirely sure how to, so I'm kind of playing and learning as I go.

For the centre you could use a transparent radial gradient  :GradientAlphaOnlyTrue::GradientTypeRadial: ... position the cursor on the centre of your screen >>> right click and draw outwards. 

It's possibly the best option ... smoother transition.

Plus, i'm not sure if you are or not but keep the brush layer/s separate from a  background, it'll be more versatile

 

Tiling ... I'm winging this whole thing as much as you ... but will have a think and maybe someone else will have an idea before I'm back later

@welshblue the transparent radial gradient is a nice trick!

 

An I still can't think about any way to do the tiling, but I don't have that much experience so hopefully you or someone else will think of a way ^^

 

And thanks for all the help!

@Pixey I actually said seamless, but welshblue said tiling which I thought had the same intention but is the correct wording :P

 

Anyway what I actually want is for the blue 'lines'/'shadowy things' you see in the first picture to be 'moveable', so over time it will look like

the lines are being 'emitted' from the center while and leaving the edges 'going offscreen'

 

Thinking about it though, I'm not sure if seamless is gonna help do that. I'm not really sure how to do it though, so any ideas are welcome!

I never see things properly 🤨

 

I'm not entirely sure here ... do you want it still or animated ?  Either way I guess you could just use Rotate/ Zoom to increase the layer sizes. 

With maybe something like Bulge to give them a different 'look' ?  I've got splinters in my fingers from scratching my head ...

@Creed31

There use to be a plugin/add-on to Paint.NET from ishani called 'Genesis VFX' that could generate an effect like the one you are requesting.

That never gotten finished. But, it could work.

@Pixey  - first of all wow, that looks like an amazing plugin!
Although it's a bit complex, and I think your result is actually seamless, but I have no idea how you got from what welshblue made to that using the plugin, if you can explain a bit?

 

@welshblue - a still image since I need it inside the engine, but if we can get a 'forever animation behavior' I can probably replicate it inside the engine.

 

 

Based on what you said I tried to play a little in the engine and I've attached a video showing it. Note that I added the black circle in the center and it's not part of the texture, but it shouldn't matter.

 

In the video I'm showing 3 different things. You can see I'm switching when you see the gray checker texture for a second. Parts:

 

1 - this is zooming of the texture from the center over time, by [0.7 .. 1.0]. The sudden jump you see is when it reaches 1.0 and jumps to 0.7

2 - this is zooming of the texture from the center over time, by [0.7 .. 1.0 .. 0.7]. You can see it goes forth and back.

3- This is just the texture it self with a black gradient circle in the center

 

What I would really want is the first effect, but forever, without it jumping to 0.7 (or at least without us noticing it).

I hope it's not too much info, I tried to explain a lot as I know the engine isn't the topic, but I'm trying to understand what kind of texture I can use to actually create the effect we are talking about.

Although there is no attached video with your above comment, I would guess that in your animated loop there are duplicate frames at the start or conclusion of your sequence that are not needed and are perceived as a 'jump' in the animated sequence. You will have to edit out these frames to get a loop that is 'seamless' when set to run as an 'infinite loop'.

 

Example Looped Sequence:

(You can right click on the 10 second sequence to turn on the infinite loop setting)

@HyReZ ha can't believe I forgot to actually put the attached video ><

 

And since I'm working inside an engine (UE4 if it matters) I'm not really sure how much I can do what you did.

But I would love to know how you did what you did anyway, perhaps I might be able to think of a way to adapt it to the engine.

 

That is, even if I had a simple animation like the first part one in my video - what would you do to make it seamless? you can't just "cut" the first/last few frames, and you can't simply copy them either since they won't be continuous

 

here it is:
