Hello all,

We are having the same issue (color distortion), using UGUI on android builds.

Image ios vs android

Hi @DragontaleStudio, it's actually a different but similar issue. Please provide us with which version of Unity and AVPro Video you're using. We did fix UGUI recently for Linear mode, so it's best if you're on the latest version of the plugin (1.10.3 now, and 1.11.0 later today).

Thanks,

[DragontaleStudio]

Hello @AndrewRH. Thanks for your prompt answer. We are using unity 2019.3.9f1 and avpro version 1.10.3 (full ios, not trial)

[AndrewRH]

Thanks @DragontaleStudio we're investigating....

[AndrewRH]

Both of these issues are caused by the Unity colorspace setting being set to Linear. If you set to Gamma then the problem will resolve. This isn't the ideal solution though, because it's meant to work in both, so we're looking into it.

[DragontaleStudio]

Thanks @AndrewRH. We changed colorspace to gamma for the time being. Please let us know once the issue is resolved.

[AndrewRH]

@RenderHeadsSte I think we may just have an #ifdef wrong or something - perhaps you could take a look? DisplayUGUI should support displaying content when Unity is in Linear colourspace correctly....If it detects the platform can't do it natively, then it uses the shader to do the conversion...

[Ste-RH]

@DragontaleStudio Can I ask if you are using the 'Fast OES' option?

[DragontaleStudio]

@RenderHeadsSte I suppose it is the "Use Fast OES path" on android settings. No we don't have it enabled. Moreover we are using a material on DisplayUGUI that help us mask it.

[AndrewRH]

Oh if you're using your own material, then that's the cause... We have our own shaders to handle things like gamma/linear etc when displaying using UGUI, but if you override the material/shader on the component, then our shader will not be used. Is there no way you could achieve the same mask effect but using another UGUI component placed at a higher layer?

[DragontaleStudio]

Hey @AndrewRH. I suppose iOS doesn't have same issue cause it is doing it natively? Is that correct? We will try to use AVpro shader and mask component at a higher level as suggested and let you know.
