Blending 3D Layer Intersections?

[Steve Roberts]

Try setting the layers’ transfer modes to “alpha add”.

Where could I find the trasfer mode. I found an add alpha under Layer>Blending Mode>Add Alpha but that didn’t seem to do much.

Do you have a screen capture you could post somewhere?

[Sara Jean]

Here’s a shot of it. I messed around with the x rotation to try to make it look more like she was laying on the ground insted off a wall of grass behind her. The intersecting line shows up on the left side of her hair. Maybe there’s an easier way to achieve the first part of the effect?

Ah. If I’m right, that has nothing to do with 3D. You could draw a mask around her and feather the mask to soften that left edge.

[Sara Jean]

Sorry, that might be a bad shot. If you look closely you can see the intersection of the layers just to the left of the left side of her hair. It runs from the bottom of the screen to 3/4th of the way up.The grass layer is tilted slightly on its x-axis.

I’ve already applied a mask to the woman’s layer. Do you think I should just pull the mask in so that the layer’s don’t intersect? Is there a way to blend intersections (for future reference)?

Thanks again for all your help!!!

Yep, apply a negative mask expansion so they don’t intersect.

The only way to fiddle with 3D intersections is by using Alpha Add mode to improve the look of the place where two layer edges meet. Transfer modes can be displayed by hitting F4. This toggles “switches” and “modes” in the timeline.

Thank you so much! I’ll give it a shot!

I’ve had success in using a masked 3D adjustment layer with a blur on it to meld together 3D edges, but this only really works with layers of solid color, otherwise you see obvious blurring of the layer’s details. The best way to avoid your problem is to make sure no 3D layers intersect!

Yeah, It’s seems like that’s the case. I was able to pull in the mask to avoid the intersection and the image looked fine. Who would of thought there wasn’t a blend layer intersections button? Ha!

Thanks Darby!
