I'm fairly new to Blender, but I hope there's a simple solution to this issue.

In Cycles I'm trying to make a composite of (soon-to-be) animated objects and video footage.

I've used nodes to apply transparent and translucent shaders to the four circle meshes (UV unwrapped with textures) and put in a simple cube for comparison's sake. (An emission shader has also been applied to the largest, yellow circle.)

This is the 3D view set to solid shading, with a background image.

viewport

Here's the rendered view:

rendered image

Why is everything so "ghostly" and pale? No shader has been applied to the cube, and the circles appear much dimmer than I need.

Is there a way to fix this? How can I make the circles appear more "solid" without losing the transparency and translucency I need? It would be ideal if it could look more like the preview in the viewport shading,

enter image description here

but I hear the viewport shading result and the final render result are never the same...

Any thoughts?

Object mesh nodes

  • $\begingroup$ The actually are the same a good amount of the time. There are only a few minor differences, see blender.stackexchange.com/q/2728/599. Do you have motion blur enabled? Or any compositing nodes? $\endgroup$ – gandalf3 Aug 31 '14 at 17:28
  • $\begingroup$ can you post a screen shot of your compositor nodes? $\endgroup$ – cegaton Aug 31 '14 at 17:41
  • $\begingroup$ Thanks for looking into my issue, gandalf3 and cegaton. Gandlaf3: I'll look into your link. Cegaton, please see my edited entry for the screencaps of my nodes. $\endgroup$ – KTS Aug 31 '14 at 17:50

Try using an Alpha over node instead of an add node:

enter image description here

The add node literally adds the pixel values of one image to the other image. This means that not only will you have both images visible at once, but you could end up with pixels brighter than 1.

  • $\begingroup$ Thank you for all your answers, both of you. Gandalf3, the "Alpha Over" is what I was looking for. Many thanks. $\endgroup$ – KTS Aug 31 '14 at 18:04
