Is someone have any problem with Xfrog flower or tree.
I have this warning when I render:
Warning: invalid texture dérivatives(UVW 0,0,1, #QNAN)
Why?
It happens when some object has problems either with UVW coordinates, or with the vertices… welding the geometry and/or texture vertices may help.
Best regards,
Vlado
I have the same problem! And it didn’t happen in the previous versions of Vray.
This message, “Warning: invalid texture dérivatives(UVW 0,0,1, #QNAN)”,
doesn’t aper once it keeps on going and I get a huge report of errors.
For me this started with 1.47.03.
are you using either EMesh or Epoly versions of the x-frog trees or your using x-frog import plugin?
the import plugin!
i dont know if its been fixed but i used to get alot of trouble with that plugin. when rendering it took forever in the calculating geometry stage as opposed to the EMesh or EPoly versions
import plugin also.
