Hey, gwardlaw. I have checked out your synths and they seem fine. What do you mean, only using two photos? Your synths work in both viewers as far as I can see. 100 % synth with point cloud and all. Maybe make sure, depending on your connection and/or computer that you have as little internet traffic during the time you are viewing your synth. That also means uploading of images for synths while viewing synths. If you are uploading while viewing, just pause the upload until you are done. I have a fairly good computer and connection and I notice a slow down or even "glitches" while viewing if my internet traffic is only slightly used.
