Hello,
I’m sorry to report that the problem seems still present.
I tried some of the infinity blade new packages, on the left, the frost giant in a new 4.9 project, on the right, the same in my project:
I have emptied the cache directory entirely several times.
When i do so, everything is fine the first time i open a skeletal mesh, but the second time (even if i open a different skeletal mesh from the IB warriors collection), the problem is back.
This happens only with the IB warriors collection, and in case this helps, i have reassigned them the UE4 mannequin skeleton from the anim starter pack.
Do you think any shader corruption could come from a change of skeleton ?
Thanks
Cedric
