Hello! I created large panoramic images (50.000x25.000 px or 1250MP) out of PTGUI as EXR Files. I´m able to open them and do some post processing in AP, but then I´m not able to save my work again. While saving the EXR Files AP crashes whitout an error report or notice. I tried EXR with and without compression. HDR File format is saved but it´s corrupted as it´s not possible to open this files again nor in AP or Photoshop. Are there any file size restrictions on 32bit images ? I have 128GB RAM so that should not be the issue. THX Marc
