Hello,
it seems that going to the material “Source” tab sometimes remove added material parameters (float vectors)
if those are crucial for the modified shader involved, then i get tons of errors in the ide (“cannot recompile shader”)
on top of that, if i dare to click on the exception, the the ide hangs and i got to restart it
or i wait then an error appear, and the ide saves a snapshot
if i re-add manualy the missign parameters in the material source, then it goes back to normal
so the shaders/material files are well written
i don’t know if it is a registered bug or anything ?
anyway just to let you know
regards
