I have a digital terrain model (DTM) and an orthophoto. After draping the orthophoto onto the DTM the colors of the image look quite different from the original, with lower contrast. Now I would like to create a 3D pdf, but in the pdf the draped image looks much darker; not satisfying at all.
Is there a way to keep the colors of the original image, so the 3D pdf looks satisfying?
thank you very much for your extensive answer!
Unfortunaly I still did not get the desired results; I keep on trying.
It is difficult to suggest an answer without knowing about your material and lighting settings.
Can you upload the dgn?
