Material Pass Help

[alewisde]

I’ve been looking everywhere but can’t seem to find a solution to this.

I’m trying to composite a sun using material/object pass but the effect isn’t being added to the scene. The sun object was placed using the sun position addon.

Here’s the result.

This is the current node setup for the rendered scene. For this thread I used a blur node and overdid the effect to show how little of it is being added.

It seems to only want to add a slight glow and some red where the effect touches the ocean.

any thoughts.

I would guess it is the final Add that you are doing is absorbing the red. After all there is red in orange and your sky is orangish. What you can try is to key out the black from the blur section of your node tree and then you will have a true alpha that you can plop the sun over top the background with an Alpha Over node.
