Acrobat DC is disabling the lights when vertex colors are used in the U3D input file, is there any way to overcome this?
I have created a U3D file with a mesh and vertex colors. I have created a PDF file using the Latex tool.
When opening the PDF file in Acrobat DC, I see that the lightning is disabled. This does not happen when the U3D file uses material colors instead of vertex colors.

Could you please share the U3D files with us with material and vertex colors?
Does this problem arises when you create the pdf using Acrobat as well?
