While attempting to process a spherical pano made of 26 raw files, there was a crash during pano rendering (all the steps before had gone without any trouble). I do not remember the message that was displayed but this was related to memory (not enough probably !).

Hence I converted the raw files to tif files and the result was perfect.

26 files - 10 MPixels/file - 10000 x 5000 rendering size
