MRay and nurbs tesselation

[stunndman]

if maya and mental-ray crashes your system must be messed up somehow - i have no problems so far rendering my nurbs models

can you confine the problem ? will it crash without textures ? will it crash if you delete all nurbs objects but one ? will it crash with an empty scene with a nurbs sphere ?

[uschi]

ok it crashes

- a complete scene
- no textures
- usualy i can render it 1 time
- i use clean up scene
- trimms and freeforms
- polygons have not that problem
- it crashes in all cases: FG, GL, raytracing


when im trying around with some easy geometry i have no problems with mr, but when im trying more complexe scenes it used to crash

[stunndman]

do you have a scene that reliably fails to render and you can share ? if so e-mail it to me and i can give it a try

if not i can only suggest to start over with a clean system (reinstall your OS and your applications)

maybe someone has less intrusive ideas

system is just 2month old

sorry, can´t share the scene because its a commercial project
with hot agreements... but i will post one scene when i´m working @home

not sure what you mean - basically mental-ray uses maya's tesselation settings or you can use the approximation editor


By default, mental ray for Maya uses Maya's tesselation settings for surface approximations. If you want to override this, you can use mental ray for Maya's Approximation Editor (Window > Rendering Editors > mental ray > Approximation Editor).
