Groups inside Mask-Groups displayed wrong(but render correct

Post by DrNibbert »

Hey everyone!

Whenever i use Groups (wheather its a Switch-, Masking- or just a normal Group) inside a Masking-Group, it gets displayed wrong in the viewport.
But when i render it out, it is displayed correkt, so i don't think its a mistake i made.

I uploaded an simple example-file, can you verify this bug?

Especially with more complex rigs this gets quite anoying.

Thanks for your feedback!

1. Do you have GPU acceleration* (un)checked?
2. Why is your mask above the masked layers?

that file works fine here -- display and render the same - win 10 12.5 (but I always have GPU off!!)

but there is a known issue with complex / nested masking where the situation is exactly as you describe. e.g. using masking to create a mask -- taking your example file -- make group 1 a "hide all" masked group with its layer 1 as add invisibly to mask; and animate the points in the rectangle to partially include the other shapes...

GPU is great for image-based files but masking anything but the most simple file fails horribly.
Don't count on the display for non-gpu display either ( at this point in time) it may be still different if complex.

FWIW, I normally have GPU Acceleration disabled too. As mentioned by Chucky, it often messes up when displaying masking. There are a few situations where enabling GPU acceleration will speed up Moho but, for me, having accurate (or mostly accurate) mask previews is far more important because I tend to use masking A LOT in my rigs.

IMO, Moho is usually fast enough with it disabled anyway.

Thanks for all your replies! You`re right, turning of GPU fixed the problem!

In another of my Rigs the Masking Group is displayed correctly WITH GPU and wrong when GPU is off :lol: Weird.
Guess i'll have to try case by case wich one works best.

Different graphics cards/chip sets and drivers might be the reason for the inconsistencies. The only way to know for sure is to try.

For me, I leave GPU acceleration off until I feel a project's interactivity is getting too slow to work with. Then I switch it on and, if it helps, I leave it on while I'm working in that project. If I see no difference in performance, I turn it off again.

A while back, I was told that the dev team was looking into improving Moho's openGL, so hopefully this means improvements for mask previews too. Just have to wait and see.
