Rensei: Sketch #54

[Rensei]

To be honest I just wanted something around the shield itself to show that it protects a larger area around the character, like an aura, and then I was just playing around with different shapes for bursts and I liked the look of that

I tired it with flat quads and you could clearly see it being very flat at some angles. Meanwhile this only uses 5 particles and it looks volumetric-ish so I’m happy with that haha

I’ll tag @atcolombini because they were curious about this as well.

So it’s just a simple mesh, top part of the sphere

The UV’s

I’m using this texture from Luos’ pack (again) scrolling it on V and scrolling voronoi for displacement (similar to the water from this post Rensei's Sketchbook - #4 by Rensei )

And then it’s just a simple single burst of 5 particles with random rotation

I think this might benefit the effect or, at least, might interest you!

Best 'Polar' option to save pinched triangles

I can’t think of any other approaches than mesh or polar coords… But I’ve started seeing the power of Polar coordinates on a flat quad/billboard rather than revolving a mesh it helped me fix seams quickly from pinched triangles without having to throw a ton of uv/vertex info into engine basics polar UV two panning textures multiplied with offsets to give hypnotic interference input Max Remap to overexpose texture; it thicken the lines at the center so you can fake some uniformity [polarBri…

Oh absolutely! I had this problem few weeks ago and read that thread so many times haha. For polar coordinates in my shader I decided to just calculate the derivatives like advised here: Best 'Polar' option to save pinched triangles - #12 by fleity

@fleity

You calculate ddx and ddy of the regular uvs and use a different sampling function tex2dgrad() instead of tex2d() (which isn’t a node in shadergraph for some reason, but you can simply use it in a custom function node).

For the above thingie I don’t use polar coordinates from the shader so the noise is sampled as usual

Thanks for the link tho, that topic is super useful~
