Need some help with rendering cryptomatte in VRay

#1

Greetings.
I have an animated scene, and I want to render it using Vray 5 in 3Ds Max, and I have the cryptomatte element active. Cryptomatte works fine when you render a single frame. You can just press the “Save all image channels to a single file” and it will save an EXR with every cryptomatte layer. But when I try rendering the animation, it merges the cryptomatte layers for each frame. I need those cryptomatte layers and I can’t just sit here and save 1440 frames one by one! So, can anyone know a way to make it save the layers automatically? Thank you.
