C4D R18 Corona Alpha Channel

[Flamingo]

Hello,

against R17, in R18 I can not see the transparency of the alpha channel in my Viewport.
In the Content Browser it is shown in black aswell
The latest release from 24.07.2017 is installed.
Can somebody help please?
In my attachment you can see the problem It is not a rendering.
In the Material Preview it is shown tranparent
Thank you

Try setting the alpha channel map to linear color profile rather than embedded or sRGB. I noticed this problem a while ago and setting all alpha maps to linear worked for me.

Let me know how you go!

Cheers,
Brad

Thank you for your answer.
I already made this. It works fine in R17 but nor R18. The alphachannel or image is not the problem.
The problem is since installing the new release from 24.07.2017.

Hi,

Would it be possible to send us the original image of the tree in original format? I would like to reproduce the problem on my development machine. Thank you.

Same here.
C4D 18.057 but I've seen this before with C4D 18.XXX. I don't know with C4D 17, I'm using Corona since C4D 18.

Thumbnail material is ok but this material assigned on a plane, I have my RVB picture on a black background.
