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?

Hi,
here are the dgn and the draped orthophoto.

Hi Markus,
In your dgn I adjusted the dcdrape material increasing the Diffuse value to 100%.
This seemed to improve to appearance of the orthophoto.
I also noticed that you have some objects that don't have a material applied. They appear overly bright. If you hadn't planned on applying a material to them you may want to reconsider this. You can easily control their brightness by assigning a simple material to those objects. To do that you can just create a new material and call it something like "Simple". Set the Base Color to Use element color (the little color palette icon). The Diffuse value should be at 50% by default. You can now apply this material to those object that don't already have materials. They will still display their original element color, but now you can control how bright they appear by adjusting the Diffuse value.
I hope this helps.
Regards,Ron
