Hi everyone,
Sorry for my english.
First the nomenclature
VFB (Vray Frame Buffer)
.vrimg - VFB saved image format
The problem is easy to solve
Follow these steps:
**1-go to the address (PC \ Users \ "YourUser") and you will see the .vrimg files that have been saved in the VFB
2-look for the last file that has been saved, and put them in another folder or delete
3-open Sketchup and VFB and try again to open the history - Solved
4- If the problem continues only check the .vrimg files that are saved in PC \ Users \ "YourUser" to see which of them is that they have to remove**
This has happened 2 or 3 times in very large and heavy files that I have saved while still rendering, the file is damaged for unknown reasons and the VFB no longer responds until the damaged file is deleted
I hope this works for you
