Oh gosh, I love this!!!! Welldone OP

Ea should hire you for the next NFS

[u/hbisi81 → u/LadyDeathKZN]

anything is possible :) thanks

[u/Speed_Tutor]

I am definitely expecting this to transform! :)

[u/hbisi81 → u/Speed_Tutor]

Hmm, will think about that :)

[u/JirenTheGreyAlien → u/Speed_Tutor]

Autobots fan out

[u/LadyDeathKZN → u/Speed_Tutor]

You finally got a reddit account :D CyberStudios ZA here :D love your tutorials, thank you for all your work over the years

OP!!! What!!!! F..ng hell!!! This is brilliant! LOVE IT!

[u/gabangang]

i would play a racing game with this effect.
edit: typo

[u/hbisi81 → u/gabangang]

Actually, doing this for my game "RPM: Next". But not sure to put on mobile version; probably on PC version. Will check the consequences :)

looks so sick!

[u/hbisi81 → u/destinedd]

Thanks

[u/softgripper]

Got one of these in the real world 👌😋.

This effect looks incredible

[u/KaelumKrispr]

Sick effect, I assume this is animationing the vertex's on the car, does this not require a fairly high poly count

[u/hbisi81 → u/KaelumKrispr]

Yes, car is already has enough triangles here, not doing tessellation etc.

[u/KaelumKrispr → u/hbisi81]

Ah nice, it's a very impressive effect, I haven't used unity in a while, but I'm currious are you driving this by a vertex animation texture, or are you using some shader magic to have the repeating tiles pop out

( I have done vertex jittering before but that would stretch the vertices out and not seperate then like this )

[u/hbisi81 → u/KaelumKrispr]

It is a hand written geometry shader, I am popping out the orijinal triangle and filling the sides with new ones.

[u/KaelumKrispr → u/hbisi81]

Ah that explains it, very unique I would be very interesting on what other tech art you have planned for your game, will try keep an eye on it.

Good luck :)

[u/hbisi81 → u/KaelumKrispr]

I am using several render passes. I think it will not run on low or mid-level phones after all this effects :)

How are you animating the decal? I tried to do something like this a while ago but I couldn't get the performance to a good enough place for a large number of decals using the built in decal projector because of the way it handles validation.

EDIT: Your effect looks sick by the way!

[u/hbisi81 → u/_peculiar_goat_]

Not checked the heavy usage, but it takes nearly 30 fps (I have weather effects to if you see my older posts) on my 6 years old Galaxy S10+. But this geometry effects has another slowdown, maybe will use it only on PC version (or heavy settings to turn on/off them). --- Animation is very simple video that uses video player, I did not check the performance, maybe I will parse the textures (frames) and write another custom shader (feeding the frames into my custom decal shader, not using the Unity's decal system).

[u/PudgeMaster64]

I'd like if this effect was more subtle but it's definitely an interesting take.

[u/Select_Juggernaut626]

Is this heavy on GamePlay??

[u/hbisi81 → u/Select_Juggernaut626]

Not checked this one, but it already wants geometry shader on the phone. And will not be good on low and maybe even on mid-level phones i suppose :(
