michael campbell (3di) added a comment to T74215: shadow catcher is showing a weird black and white reflection which doesn't appear in any of the passes (so can't be removed). Causing problems with composition..

Actually I think I spoke too soon. The reflection is still there even if I replace the direct glossy with the direct glossy from the second scene, because the black and white unwanted shadow isn't in the direct glossy pass in the original scene.

Hi, thanks for the workaround, I didn't consider using the cryptomatte! :) I could have sworn blind that the shadow catcher only showed shadows in 2.8, but I've just double checked and it seems I was wrong. Thanks again.

if there was a way to exclude the hdri from reflecting in specific objects that would remove the need for a shadow catcher and resolve the problem. Perhaps two additional outputs in the light path node (object id and material id), then you could use that in the world shader editor to use different backgrounds on a per object/material basis.

Bit there’s nothing wrong with the shadow catcher, the bug is with ALL objects masking the environment pass. There is no situation where this is needed, and it’s meaning you have to render twice (rendering the environment pass in its own view layer with everything else hidden)

I should point out that the only reason that the glass data isn't included in the environment pass is because I used the transparent glass option in the render settings's film panel.

Would it not make more sense to just have options to emit from face, edges, vertices (with the ability to select all 3)? And then have an offset option in scene units. The initial velocity shouldn't really be anything to do with where the water is emitting from or how far from the object it starts.

The original file may have been created in one of the previous daily builds somewhere between 2.8 and yesterdays daily 2.81 build, I'm not sure which. When I've finished these few projects I'll have a dig around to try and find another file which has the same issue, or hopefully before then someone else will experience the same problem with a file they can share.

ah ok, I couldnt share the file as it's under NDA,. If you want to replicate, you could create a scene in 2.8 which has a hdri, and then open it the latest daily build. It's definitely not caused by multiple importance sampling now being the default, otherwise new nodes would have had the same issue. I'll leave it with you.

It's because background multiple importance sampling is now enabled by default, which requires a rebuild when rotating.
We would like to optimize this in the future, but it's not a bug.

2.8 was very fast to update modifications to the hdri rotation, strength etc (the same as 2.81 is now that I deleted and replaced the environment texture node and the background shader). I was mistaken regarding 2.81 not initiating the update until the mouse button is released though, it updates when mouse movement has stopped for a second or two whilst the mouse button is still depressed.

I think the coding of the background shader or environment texture must have changed somehow, because adding new ones seem to be back working as expected....although I did think that the behaviour of the slider used to update the render as you moved, now it seems to only update the render on mouse release which takes away the interactivity somewhat (which is important when tweaking lighting).
