Help WebGL effect: glowing water portal

hi all, I'm trying to create a look similar to a Stargate, but not exactly the same - just some sort of dimensional portal.

I'm trying to do a combination of blend layers, Force Own Texture, and using the water effect, but it's not working out too well.

Any ideas?

The quickest most effective way would be to use an animated sprite with a blend mode.

You'll have much more to work with using effects and filters in a true image editing program like blender or Photoshop/gimp. The built in effects will only get you so far.

It is especially recommended to just make an animated sprite if it's a one off or repeated scene that doesn't change or need to be generated flexibly on the fly.

are you thinking about a particular blend mode? like additive for a glowing light effect?

Additive should work fine. But you can use any blend mode really, it would just be using different design/colors for the base image/animation. Additive is generally the most intuitive to blend over a background though

Try some bump mapping.

Addon here:

newt wow that is super cool!

I don't quite understand what that addon is doing. Looks like its putting a light at the back of the layer? and it outlining sprites?

I've played around with normal height maps in unity and with a graphics editor, but that was a range of colors.

Height and bump mapping simulate light depth by having certain pixels (based on a prerendered map) on an image be affected by a simulated light by different amounts, depending on what is specified by the map. It allows the illusion of 3d lighting in 2d.

Yeah, usually these fx use a mask or map. This one just uses the light and dark values of the texture itself.

ah that makes sense... so its using the blend or how much of the blend white to black for the "bump" or height... interesting...I guess its that way because the original shader was just for light reflections.
