Inventor 2025.3 Bug: Transparent images do not get exported correctly anymore.

[ErikStoeken]

Since updating Inventor to version 2025.3, exporting images with a transparent background no longer works correctly.

It seems that the exported PNG shows inverted colors instead of having a transparent background. This issue only started occurring after the update to Inventor 2025.3.

I’ve attached two images to this post. One was exported with the "Transparent Background" option turned off, and it shows the correct colors. The other was exported with the "Transparent Background" option turned on, and it displays a blue background and shades the part differently.

Hopefully this can get fixed soon!

Our company systems run on these images from Inventor, I hope it can be fixed soon!
