material value doesn't change at runtime

[safe sable]

this is whole code

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;

public class materialIntensityChanger : MonoBehaviour
{
    [SerializeField] float speed;
    [SerializeField] float range;
    [SerializeField] Material material;
    // Start is called before the first frame update
    void Start()
    {
    }

    // Update is called once per frame
    void Update()
    {
        material.SetFloat("_EmissiveIntensity", Mathf.PingPong(Time.time * speed, range));
    }
}

this is problem

it is changing in game, only if i click and drag the value

material value doesn't change at runtime

Probably because the value changes so drastically when you drag. Try setting the starting value to 0 and increasing the speed to 100 or something.

[safe sable]

actually the starting value is 0 at mathf.pingpong

also the value is changing everytime when i don't touch, you see

[thorny stirrup]

From what I've seen in the video it starts from ~5 and goes up slowly.

[safe sable]

no it comes up to "24" (EV100) value that wanted. i made the speed 5000 as you see in last of video

i don't think it's about codes or something like that simple, it's probably about shaders or some systemical thing

[thorny stirrup]

You changed the speed but it doesn't seem to affect anything. It still increases super slow. Not to mention that it should jump between 2 ranges instead of increasing indefinitely.

But yeah, it does look weird.

What I'd try to do first is get an active camera enabled in the scene, because it looks like you don't have one.

As well as address the errors in the console.

ok, it didn't fix but thanks anyway.

anyone else has an idea?

hi guys i found an alternative idea

this doesn't change the "intensity" but it can change the brightness.

if you enabled the emission and entered your emission valu true, then enable the "emission multiply"

it multiplies the emission with main color

so you just need to make main color increase and decrease

i mean make main color black and white with the same "matfh.pingpong" function

then the object's brightness is increase and decrease
