Hi guys,
This is my second post here regarding the custom shaders in Corona.
I played a bit with different shaders from Shadertoy and mixed several of them to create a portal effect, although it’s not fully complete.
Here is the link for the Corona Shader Playground: https://goo.gl/Uxn7VQ
Basically, what I want to achieve here is to make the black rotating part white instead. I tried playing with the code but couldn’t do it.
If anyone has any knowledge on how to achieve this I’d be really grateful.
Thank you all and have a nice day!
Hi.
It seems okay with these two lines at the end:
P\_COLOR float c = step(f, .05); // some arbitrary threshold return CoronaColorScale(vec4(max((f\*horColour), vec3(c)) , 1.0));
although the inner circle is sensitive to that threshold’s value.

Hi StarCrunch,
Thank you for your help and for your fast answer! I will play a bit more with this shader and if something good comes out of it I’ll definitely share it
Randomly stumbled across this thread. My suggestion would be this:
return CoronaColorScale(vec4((1.-f\*horColour) , 1.0));
and then fix the colours in the //get the colour bit.
