Maya 2018 - Render Sequences damages materials, why?


#1

Hi, my scene was done with Maya 2018 and using Arnold Materials,

for some estrange reason if i click “render” for testing ilumination, quality, etc, my textures look perfect with Arnold; but when i click “render sequence” to start rendering the entire scene in exr stills, some of my textures change, i thought render sequences was the same thing but after render sequences some of my textures even show some kind of noise like big horrible boubles and other objects rotate wrong… so weird, some scenes with render sequences show the exact textures fine and in other scenes it destroys it… like if render sequences some times work fine and some times gets drunk, it never happened to me with Maya 2017, it´s an odd behaviour.

but if i stop render sequences and just click “render” at the same exact frame, my scene appears normal like everything is ok, without any issue, is this another Maya 2018 bug? i already tried to change materials, but same effect… i cant delete history because i will loose all my rigging, bind, weights, deformers and they were hard to make… why render sequences give a different and bad resoult? am i gonna loose all my work because render sequences is drunk? my only choice now is to render each frame manually…horrible, but at least that works.

I already had another problem with render sequences some days ago: another of my characters deformed perfect on viewport and after render with arnold for testing, but when clicking render sequences all “deformers” of a bodypart didn´t work in render sequences…LOL i had to delete history and redo those deformers completly just for render sequences, even if it looked perfect on a normal render. but at least that was an easy part to solve because it was an individual small piece.

Now i have to cross fingers and make a prayer before clicking “render sequence” because i have no idea what is not going to work… after days of render sequences even if i previously tested everything with Arnold, maybe render sequences have IA and it is attacking me like in Terminator movies… LOL. Sorry i just have to lough a bit, im soo mad.

could you post a repro scene here.? or just one object with this behavior.?

That would be great. And if you are able to reproduce the behaviour with a single object, please report a bug to Autodesk.
