i tried to export images of my production with the operator [RenderImagesToFile].it always ends up with very low brightness values.my last op before export is a [RenderToImage], it looks like this:
[RenderImagesToFile] creates this - on the right you see the original export and with gamma x4. so there is a lot of data missing.
any idea what i am missing?i did this with version 2.4.
Interesting problem. Excellent bug-report, too. Can you export the BTTF-Operator and share the archive?
the BTTF-operator is the uppermost node of my demo "breathe" from evoke. find it here:https://files.scene.org/view/parties/2016/evoke16/demo/breathe.zip
i had brightness issues before when going 2d->3d with a [Layer2d] - this was caused by glow operators which created insanely high values. i didnt know how to clamp them.
Thanks again for reporting this issue.
Do you know the [Waveform] operator? It helps to debug things related to colors-ranges and alpha-channel.
I spent some time looking into this issue and discovered, that the blend-mode of the [Layer2d]-Operators seems to implement an invalid blending for alpha. You can fix this issue be inserting any image-effect Operator like [ChannelMixer] or [ColorGrade] between [RenderToImage] and [RenderFiles]
You could als try to connect the [RenderToFiles] directly to the [BlendImagesAdd] below the Layer2d. I investigate some more though.
ps. nice demo btw. Looks very structured. Keep in mind that blending too many RenderBuffers might slow down performance quite a bit. Using scene operators something like...
...can be much faster.
this is handy, thx.
this didnt help, same result.
i tried that before, same result...
this is a supernice hint! i didnt know that this is possible - beginners prob thank you!
