Blackmagic Forum

When a video is connected to a uImagePlane, the viewer doesn't update (same thing with uRenderer), it displays a static image.

It only updates the static frame when the source is modified, like if we add a mask to it.

And if we deleted the mask, the viewer doesn't update either and keep the image masked

Fusion Standalone doesn't seem to have this color problem, but the other problems are similar.

here, I deleted the ellipse mask


And here it was an accident, and copy/paste the mediain, it created a merge.
Look at the colors?!


Dragging the uImagePlane in a viewer restores the washed up colors

Usd system is not functional without uimage plane working properly. I described a similar bug a few months ago: https://forum.blackmagicdesign.com/view ... 2&t=192400
Unfortunately it was never fixed

I guess that it is still a problem in 19.1? (I didn't try it since)

Yeah, it's still a problem

Animated textures are a big deal. Using an actual input from a 2D node stream is a big deal. At this point the USD is only good for roughing things for other programs. Why would they not just make it compatible with a Loader/MediaIn node? Why break the basic, standard way of working just for USD? Now I can't track USD textures with the rest of my project. It's a bad implementation. It needs integration with the rest of Fusion's tools.

For a development team that takes years to do anything in Fusion, I feel like trying to tackle USD was a waste of time. Keyframe Timeline Refresh, PBR, Multitool Attribute changing, Guides and Rulers, Fluid algorithms for particles, Color page preview in the Viewers, Scaling the node flow smaller, Moving all selected tools in a viewer, Revamped text tool, Tapered poly lines, Modifiers as nodes, Parity with Resolve's FXs, working Cryptomattes, a Cache node...

Every one of these would make more of a difference than getting USD with a Storm renderer barely working. It could have been a skunk works project for years until you could actually use it with the rest of the program. Till then, give us the tools we use with improvements.

Has anything animated as a input ever been supported by the USD system in fusion? Since it was introduced?

I think the question to ask is, has any other software implementation of USD limited textures to not being animated? Furthermore, has another implementation not had material based animation implemented from first introduction?

It's kinda useless to introduce a Universal Scene Description system if it's not fully implemented nor Universal. Then, I'm just back to exporting geometry and textures separately into a folder. At least if I do that with an FBX, I get texture sequences.

This is a perfect example of the devs not using the program. If they actually did 3D compositing in the last fifteen years, this type of stuff wouldn't need to be called out. Instead we sound like cat ladies yelling into the wind for two years about something as basic as animated textures. And here you are implying that we shouldn't expect it because it wasn't in the release yet. And to answer the next question. Yes, it should have worked from day one with inputs from a network. Without that feature it's just about useless.

This frustration is about the devs not you Kruno.

A bug is not what you the user want, but is what developer wants and fails. I don't know if the design ever included animation, I haven't used USD until they fixed the bugs so I can actually try it. For people with my hardware, until 19.0.3 it didn't load at all. I didn't use it much in the version 18 because it was really basic. So I don't know if it was always like this, but I think Alexander Ezhov posted about it, so I would assume it was. Meaning its probably not a bug, just unfinished USD implementation.

I agree, by the way, that animation should be supported and that it should do all classic 3D system does in fusion and more and better for being newer system. I also discovered its not loading animation , which was disappointing, since I figured out how to use it for adding shadows to transparent image input, but no animation. Classical 3D system can only do it, even with animation when using software renderer which is very slow on CPU only. And USD supports GPU so its much faster, however to my disappointment, no animation support... yet.

However I do see that its very much still in early phases of development and clearly Blackmagic has added more options to it since it was introduced, even inbetween 19.0.3 and 19.1 they added: Support for USD 24.08 with improved MaterialX performance.

So clearly, development is in process. Unlike classical 3D system that is not getting much love anymore, so I expect at some point they will continue USD development until its better than classical 3D system. For now, it seems to be WIP (Work in Progress) not really ready for prime time production unless you really are desporate. For now, I would wait and see what BMD does with it.

So the traditional way of creating a specular AOV and a Shadow AOV is to double/triple render the scene with lighting enabled/disabled and shadows enabled/disabled as to use a Boolean to subtract the scene from the shadows or highlights. Do we know if an AOV render carries the same expense?



If you can't use animated inputs, what's the point of a uImagePlane anyways? Hey look, here's a rectangle in 3D space with a picture on it.
