Color Picker sliders in Material Editor Stiff

Hello, not sure this would be considered a bug, but I thought this is the best place for it. Basically I’ve noticed in the color picker in the material editor, the sliders are really stiff. What I mean by that is when I try to use them, it stutters for like, a microsecond and then updates. It does not do this in other parts of the engine, just the material editor. Not critical, but it is a bit annoying. This also happens in 4.11 but I feel like it didn’t always behave this way in earlier versions.

Hey johna0531,

I am not getting the same performance issues and stutters you are mentioning. Could you provide me with your ‘dxdiag’ so I can take a look at your system’s specs?

There could be a number of reasons the hitching is occurring, and I am willing to guess that the materials you are editing are somewhat complex? You might want to look into disabling some of the realtime updating features within the Material Editor to see if that helps resolve the issue.

The options like Live Update, Live Nodes, and Live Preview can have a performance impact, especially if you have a complex material running on a mid-spec range machine.

Let me know if you have further questions or need additional assistance.

Cheers,

I’ve attached the dxdiag below. It’s not the materials. Even when I open the material editor for a test with it blank and me just creating a vector 3 to pick a base color, the box still lags. And I don’t think it’s tied to my PC’s performance capability because

This only happens in the material editor it doesn’t happen in the main editor, so for instance when I change the color of a folder in the content browser, that box’s sliders are smooth. And I have a pretty beefy system from what you’ll see.

I am still having trouble reproducing the issue on my end. I have attempted moving all the sliders while in the Material Editor, but with no success. Unfortunately, if I cannot get a repro case on my end, then reporting this as a bug is going to be difficult.

Would you be able to shed some more light on the repro steps?

Some screenshots outlining what sliders you are referring in the Color Picker might also help identify the issue.

Thanks,

Did a screen capture of what I mean. https://drive.google.com/open?id=0B_OAOG1PfXN7dzJRT3RzWkpWaEk

So I did a little bit more digging and found this was reported back in 4.11, but was returned as By Design. The reason being is that, the preview material needs to be recompiled when changes to the constant node are made, which takes time. The only workaround would be to disable preview update while choosing colors, but I think it would be less usable.

Thanks,

ok. I did find a work around. If instead of double clicking the thumbnail to pick the color, if you click the parameter color box in the details panel, it is smooth. So I’m not sure why that is smooth and the double click pop up is not if the reason you gave is correct? Regardless, I’ll just use this in the future. Thank you for your assistance.
