i all, im getting theese Random bad frames (appr. 3 frames in a 200 frames animation) When Rendering with mental ray for Maya 2010.
The errors are always the last squares that mental ray renders. And if i render a frame that i know is bad like this, mental ray stops working and render every frame afterwards like this, just the whole frame is wrong not just the last rendered squares and i have to restart maya to be able to render normal again.
I can render the same frame from a different camera angle without problems, but swapping the camera with a new one with same angle still gives the bad frames. It doesnt matter what computer in the farm that render the frame all gives theese bad frames.
I found a solution but its not an optimal solution, after rendering i detect all the bad frames and If my Primary render is set to Raytracing, i change the Primary Render to Scanline.
If my Primary render is set to Scanline i change it to Raytracing and rerender the bad frames and they come out perfect.
When rendering im not getting close to using all memory on any machines.
The bottle consists of 3 layers of Geometry with 3 different shaders.
Outer layer (droplets) is a Mia_Material with displacement drops and a cutout map.
middle layer (bottle) is a dielectric_material
Inner layer (Fluid) is a dielectric_material.
Im working om Mac os X 10.5.8
Has anyone had similar problems or have a solution, and will mental Ray 3.8 for maya 2011 give me the same problems?
