Displacement and Dynamic memory?

[Giovanni]

Hi all,
I set dynamic memory as low as 200megs, but my displacement grass still crashes vray...

Turning displacement off for that material solves the crashes.

Is dynamic memory management not affecting displacement?
I thought dynamic mem would also work with displacement micro-triangles...

vray r4, MAX 9 32

thank you

Gio!
What are your displacement settings?

[Giovanni]

Well, I actually left them to default...

thanks

are you displacing an autocad mesh?

[Candelero]

are you displacing an autocad mesh?

Can you show us the wire, please

Best regards,

No Autocad, but revit mesh (DWG).

Now that I think of it, the meshes I am displacing using the 2D modifier are fine, another series of meshes I am displacing unsing the displace slot in the vray material may be the ones that crash vray...

Having to apply the displ mod is a pain, sometimes, because whe I update the DWG, some (old) elements will have the modifie, some (new) elements will not, althought they will have the same material....

Is there a way to select all istances of an instanced modifier? that would help...

I will try 2D displ. and see if I can render...

thanks all
