In PhAB project I put PtBkgd inside PtDBContainer.
This PtBkgd image contain abnormal black dots grid.
Is it way to resolve this problem ?
What kind of image did you set for the background widget? There are some known issues with png files with alpha maps.
In Photon 1.14 I open a New project, put default PtDBContainer in
the New window and then put default PtBkgd widget in
PtDBContainer.
You can see abnormal black dots grid.
To compare you can put another default PtBkgd widget to a clear window plase.
Thank you
I have not used 1.14 in years. Someone else will have to comment on that situation.
