Hi Community,

i try to add a decal with big letters on my part. For this i have made a transparent .png file.

Unfortunatelly I am not able to make this decal really transparent, because i must choose a colour.

Please see attached picture and I hope you will understand.

Thanks a lot for your help.

Andreas

You use the image editor in Creo to set the alpha channel.

It is highly criptic but it does work if you guess correctly.

It is best to make the transparent color either fully black or fully white.

The file is saved as .TX4 to tell the renderer it is a 32bit file (w/alpha channel) IIRC.

Hi Everybody,

thanks a lot, this was all really helpful. Finaly it works, but it was not easy. Much more complicated than in Solidworks.

A few things i want tell you.

- The alpha channel settings are hard to understand. To eliminate the white backround i have sucsess with these settings:

- Because I have a few surfaces in brushed metal without logo and one surface with logo I just copy the color "brushed metal" and add only to this copy the decal. So my Part now has 2 different brushed metal colors, one for normal surfaces and one for the logo surface.

I am sure, for this problem exist better solutions, right?

Have a good day and greetings from Germany

I took a .png that included transparency and used it as a decal and had no trouble -after- I set the transparency of the highlight color to 100%. No need to use the image editor.
