Hello,

It look like the problem is with the RailClone objects, when we hide them - 3DS Max does not crash.
We will make some more tests and will update you again.

Which version of RailClone do you use?

[funonfun]

thank your help and test

i use RailClone pro 2.5.



i convert RC objs into standalone objects and now work fine

but i notice the other issue about RT


1.



i test animation with local render

first frame is work fine

but RT crash while go to next frame

i test some parameter for animation



i change light cache mode from single frame into fly-through and work fine.

2.

save and open same file

3ds max is still crash again

i turn off frame buffer and it is work(no more crash)

i dont know which part cause of the crash

Would it be possible to send us version of the scene with standalone RC objects and let us know what steps we should follow in order to reproduce both issues?
Let us also know how much memory the machine has and how much from it is occupied during the rendering?

Thank you very much in advance.

thank your reply

i have sent the file to support@chaosgroup.com

and here are machine information

Thank you very much for the scene.
The crash is actually triggered not by RC standalone objects but by objects with VRayDisplacementMod.
There is a bug with 2D Mapping displacement of VRayDisplacementMod which cause this crash.

Please either remove all VRayDisplacement modifiers from the scene or switch their mode to 3D Mapping instead 2D.

Hello,

The crash with 2D Displacement mode is fixed for the next service pack.
