(Webgl2 / WebGPU support) A better outline shader than the one that already exists on the C3 addon stack exchange.
For the alpha, I keep forgetting exactly how the shader works because I've made alterations in the past to accomodate for people asking for slightly different outline behaviors.
If you know a little bit about shader dev, it should be very easy to change the addon to add a percent parameter and multiply the final outline alpha by your new parameter.
I don't have a lot of time to make that adjustment right now, sorry. If you need help figuring it out, I would recommend heading to the Construct Community Discord server where me or any other shader dev can point you in the right direction :)
Thanks for the heads up. I'll look into the file, worst case, I'll just make a quick function that finds all of the text, duplicates it a z under and adds the effect with the lower opacity haha.
