Cam flickering (vibrate) every 2-5 seconds

hi .

i have this problem Camera flickering every 2-5 seconds this problem happen on iPhone and some times in editor .


this is a post like this http://forum.unity3d.com/threads/67770-Vibarating-Mesh-in-Unity-3-(Filckering)?p=433457#post433457

and here a test , you can see the more flickering on the device

 

up

 

A new test Tunnel runner exemple projet of unity !!! you can see the flick on device but also in editor but less

 

other test , install on idevice and look at the bottom of the screen

 

I haven't checked but often a shaky camera is fixed if there is a physics sim in progress by putting it in FixedUpdate rather than Update.

thank you for reply but i have already use FixedUpdate but is the result .

 

Have u installed newest Unity build 3.1.4f I think ? I read somewhere that the hotfix cured some in editor flickering?

 

yes i have , but this issue in also in 1.7 , 3.0 , 3.1 and now 3.1.0f4 (55865) ...

Do you have install the test package ?

 

New test using code founded in documentation :
file:///Applications/Unity/Unity.app/Contents/Documentation/Documentation/ScriptReference/Material-mainTextureOffset.html

Code (csharp):

1.  
2. var scrollSpeed : float = 0.5;
3.  
4. function Update() {
5.     var offset : float = Time.time * scrollSpeed;
6.     renderer.material.mainTextureOffset = Vector2 (offset, 0);
7. }
8.  

 

Use interpolation on physical objects to remove stutter or jerking.

 

in the game there is not any physical objects , this is a bug in the rendering engine .

in the last test the cam do not move , there is only a scrolling texture .

 

1. check you are using floats to scroll
2. make sure you multiply it by delta time

If you don't, it'll look crap. Doesnt seem like a bug to me, just you're not coding it right.

 

with this new code here the same result !!!

Code (csharp):

1.  
2. private var speed : float = 1 ;
3. private var offset : float = 0 ;
4.  
5. function Update() {
6.     offset += Time.deltaTime*speed ;
7.     renderer.material.mainTextureOffset = Vector2 (offset, 0);
8. }

I haven't looked at the package but since it is intermittent and you are scrolling through a texture that perhaps it gets to the end and reloads the texture instead of reusing it? Just a shot to try and pinpoint the cause.

the last package is only a test without moving the main camera ... in my game i move the Cam.

Can you install it to see ?

 

I have it running right now with no flicker at all. It is three layers of checks moving past each other at different rates and I get 2500+ FPS. One draw call, Batched = 3, VRAM at 5.3MB. I am on OS X and this was with Unity 3.0f1.
