Weird effect when using glow on gui viewport

Troubleshooting graphics
1

If i use a bloom processor on the gui viewport i have a weird effect. It works fine if i use it on the scene viewport.

I followed the instructions from https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:advanced:bloom_and_glow?s%5B%5D=glow



Is the glowing effect meant to work in the gui viewport?

I dont think it is…

Not at all....never came to my mind that it could be used like this to be honest :p

Damn… :wink:

Could you elaborate? Maybe we can find a way to work around this.

What is it you want to make glow? BitmapText ?

Actually there are textured quads(with alpha channel), colored quads and bitmaptext, everything that is used for a gui and rendered as “2D” components. Perhaps the easiest way to handle this is to use the standard viewport and put the gui in the gui bucket but i think you guy’s had a reason for the gui viewport to be the standard location for the gui.

Is there anything new on this since then btw? Could be really usefull for hovereffects and similar.

8

nope, i have to look at this

I don’t see any reason why bloom would not be compatible with this, after all, its an image-based effect

10

yeah it should, but apparently it doesn’t :stuck_out_tongue:

11

What’s the mat’s materialDefinition?

12

I don’t know, its a picture:

[java]Picture pic = new Picture(“HUD Picture”);

pic.setImage(assetManager, “Interface/small/x.png”, true);

guiNode.attachChild(pic);[/java]



Btw maybe it had been better to make a new thread (called “Can’t use glow on hud picture” or something). If some admin wants to do that…

I’m trying to add a glow color to a picture in the gui node this way:

[java]Material mat = pic.getMaterial();

mat.setColor(“GlowColor”, ColorRGBA.White);

fpp=new FilterPostProcessor(assetManager);

BloomFilter bloom= new BloomFilter(BloomFilter.GlowMode.Objects);

fpp.addFilter(bloom);

viewPort.addProcessor(fpp);[/java]



but get IllegalArgumentException: Material parameter is not defined: GlowColor

14

Ok, picture uses the gui.j3md material definition and it doesn’t support glow.



Also, i’m not sure that it would yield what you expect as a result even if it was.



This would just make a white glowing square on the screen, is it what you want?

15

Thanks for your answer.



No, I need a glow around the picture… but I forgot it has a transparent background, the glow would be anyways around the square and not the shape… :confused:



Probably I have to create images with the “effect” and swap.

16

Why don’t you just do the effect in photoshop? :?

17

That’s what I meant with “create images”.
