3D Directx rendering

[ashrafs60154623]

We have a 3D PDF file generated and which uses reflection maps.

It works great on different machines.

When testing it on an updated windows 10 with nvidia 1080 the geometry appears black.

We are using the latest version of Acrobat reader 2018.009.20050

We did some investigation and we believe that is it using Software rendering, or reverts back to software instead of using DirectX on there new video cards.

Following is the good image with DirectX rendering

Bad image on the machine with Nvidia 1080

Hi Ashrafs,

Sorry for the delay in response.

As you have mentioned above that the image changes when you open the file on a machine with Nvidia 1080.

Try once updating the application to the latest patch released and check if you still experience the issue.

Also, is it possible to share the original file with us, so we can check it at our end?

You may take help of the steps mentioned here How to share a file using Adobe Document Cloud to share the file.

Let us know if you need any help.

We will be waiting for your response.

Regards,

Meenakshi

My guess is that it is using the video card but there is a problem in the driver. Updating Windows 10 replaces that driver sometimes so check the version installed against the NVIDIA site.

I am curious to know if you have found a driver that fixes your issue?

Do you know of any recommended drivers from Adobe that would make this work?

I have found that this is an issue with a setting in Acrobat Preference -> Security (Enhanced) -> Enable Protected Mode at Startup.

When this option is checked (which it is by default) then Acrobat does not seem to trust certain graphics cards, in my case its also a 1080 on Windows 10, but other users have different setups. So what Acrobat does is simply disable Hardware Rendering, so as you have noted it reverts back to software rendering which does not support Environment maps.

To me this is a disaster situation since you simply can not recommend end users to update their drivers, or disable a security setting, just to view a 3D model in a PDF document. Adobe needs to address this security settings issue.
