Hello ! I just downloaded last build for blender 3.0 alpha, and I have a strange problem for rendering:
It’s doing very small square rendering from the center in circle !
I didn’t have this problem before and I don’t think I changed anything in the settings…
And renders that took 1mn before now take forever 
look at the video…
Do you have any idea what is going on and what I should do ?
thanks in advance !
Isn’t there a ‘render tile size’ somewhere in Cycles for B3.0? That would be my first check for this.
If there is and set correctly, it’s a bug I guess 
Hello thanks ! I think there’s no anymore tiles in blender 3.0… In previous version it was rendering the whole image directly and it was sooo faaaaaaaast… Don’t know what happened, may be a bug… I’ll use previous version waiting it’s solved 
Hi,
Be sure to log the bug in some way. It might be easy to fix
Under Performance. Don’t know for optix. Whole image directly ??? With Cycles ???
Cycles x has no tile render 3.0 still render in tile i think u should check tile size and your resolution. And res % can be too high.
exactly, but do you know how to render from center? it renders the tiles from bottom left
Check Render Proporties > Performance > Tiles > Order Tab
Under the order tab you can select tile method “Center” is you looking for.
Yes, as I said, this setting has been removed after cycles x.
Right, sorry didnt notice … deleted
