Hi @tnsurveying

This could be related to an outdated GPU driver. PIX4Dmapper trial gives you full access to all the features. So have no worries about the trial. It’s only the Discovery mode that has limited features. For more info:
Pix4Ddiscovery / Discovery mode

Could you check if updating the GPU driver helps?

If you use a NVIDIA GPU, you can follow this article: How to update the driver for an NVIDIA graphics card - PIX4Dmapper
