How to handle big arrays

[nimble abyss]

if you dont know if you make big array in Shader editor godot crashes
so how we devlopers going to Handle big arrays like 262144 elements

I know you use Vector2 inside your Array, have you tried this: https://docs.godotengine.org/en/stable/classes/class_packedvector2array.html#class-packedvector2array

First line sounds very relevant: "An array specifically designed to hold Vector2. Packs data tightly, so it saves memory for large array sizes."

Sorry for confusion I forgot to type I am trying to do that in shader editor.

Right now I am packing arrays to texture but it is feels like not right way do that

Iirc that's like, basically what a lookup table is, innit?

[nimble abyss]

if you have time can you give me minimal example lookup table in godots shader language or just send tutorial any refrence link

I don't have any experience/resources in doing so unfortunately, was just saying that what you're doing with packing things to a texture is a type of lookup table

since you mentioned it feels like it's not the right way to do so

I think the normal way to do it is to turn it into a texture, which I think can be up to 16384x16384 pixels in size

(which is 268,435,456 elements)

yes but mobile wont support texture that big

and you need to calculate texture uv position for no reason

if you want to use array
