Soft Edge Strange Behavior

[elgarf]

Hi!

We have comp size 2050x1754 with two datapath x4 as display screens (2048x1536), into advanced output we created slices, corresponding our setup.
We need to make 3 panoramic projections. All ok with softedge switched off. We switch softedge on, and see that on two walls (which are top and bottom rectangles on rect.png image) softedge works odd: looks like, that Resolume think, that Screen1.Slice2 is not on the bottom of comp, but on the top. If I move Screen1.Slice2 right, I see, that into some position this effect goes off. It works on GTX 1060, GTX 970M, Radeon R9 (on mac). I attached composition, rect.png and screensetup to this post.

Also I saw image on projection EVEN when screen type is virtual (mac/win).

As a fast workaround I created virtual screen, that is the same as comp, and set source for Screen1.Slice2, Screen1.Slice3 to virtual screen (named virtual). Because wee need to work anyway)

looks like when the slice is snapped to the bottom of the screen the slice thinks it has to blend with the slice on the top.
move your Screen 1 slice2 one pixel up, that worked for me as a workaround.

Yep, but that's strange - when you change the width of the slice it doesn't blend with the slice on the top (maybe recalc snapping). Looks like it's snapping bug or something else...

I tried to recreate your mapping from scratch and I got the same problem you're getting. Similar solution to Ravensc, except that by reducing the heights of the two bottom slices down to 511.99 instead of 512 solves the soft edge issue.

So yes it seems that it's a 360˚ blending issue and actually I would love the ability to turn that option off in a future release because it always creates issues for me when I'm mapping with multiple projectors.

I'm attaching the xml file with the correction for you to test.

Thanks, Oaktown.

There is also strange thing, I don't know is it recreatable, but:
1) connect external monitor
2) set Screen 1 output to connected external monitor

But on monitor I don't see image from Screen 1 - I see image from Screen 2...

Thanks for the detective work, guys. Recreated and ticket made.
