Post Effects – preview
Hi
I am working on a project which uses a lot of post effects (highlights and glow mainly).
So far as I can tell the only way to preview what you have done is by rendering to picture viewer. I need to use an alpha channel for compositing later on.
My problem is that in the Picture Viewer, as my image renders I can see the alpha channel, kind of overlaid onto my image. This is really ugly and stops me from seeing how my post effects look.
I’ve tried the options in view, channel etc (in picture viewer) but I can’t change it so it looks normal. I am having to load the image into my compositing software just to preview ‘on black’.
Am I missing something?

need more info. A render perhaps, or the scene to look at. Can’t tell what the problem is yet.

Hi,
I have found a way around it – have to un-check the alpha channel setting in the render settings.
But here is a screen shot of what I meant:

On the left is with alpha off, and on the right, on.
It’s no problem to just turn off alpha while I am previewing my post effects..
Unless I can preview them directly in my viewport render? thus meaning I don’t have to constantly check on and off ‘render all frames / current frame’ when checking the animation / post effect.
Thanks for your response

I can’t recreate your problem here. Have you had the same problem in other files?

me too, I’d have to see the scene… as to the render, post effects do render in the viewport so you should be able to see them there
