vrend

The vrend command is used to start a v-ray render.

mc.vrend(*args)

It seems that every flag EXCEPT for -bake, -camera {CAM} doesn't do anything at all.

Flags

"-camera {CAM}"

Choose the camera to render with.

• {CAM}: The name of the camera

---

"-layer", {LAYER}

This doesn't seem to do anything.

To render another layer actually switch to another render layer through the mc.editRenderLayerGlobals() function.

Choose the renderlayer that needs to be rendered.

• {LAYER}: The renderlayer to render.

---

"-w", {WIDTH}

This doesn't seem to do anything.

The width for the render output.

• {WIDTH}: Width as an integer.

---

"-h", {HEIGHT}

This doesn't seem to do anything.

The height for the render output.

• {HEIGHT}: Height as an integer.

---

"-bake"

Do a bake render.

---

"-batch"

This doesn't seem to do anything.

Renders as batch render?

Examples

Start a render:

import maya.cmds as mc
mc.vrend()

Bake using the bake settings that are in the scene: This is basically what the mel script vrayStartBake does.

import maya.cmds as mc
currentLayer = mc.editRenderLayerGlobals(q=1, currentRenderLayer=True)
mc.vrend("-camera", "persp", "-layer", currentLayer, "-bake")
