Vray multibake textures

[ludogemma]

Hi all,

Me and my friend are trying to find a way to bake multiple texture with vray in blender,
after some help we use this script:

import bpy

sce = bpy.context.scene

# Enable autosave
sce.vray.exporter.auto_save_render = True
sce.vray.SettingsOutput.img_dir = "//bake/"

# Enable Bake
sce.vray.VRayBake.use = True

# Manual object list:
ob = ['cube','plane']
# for ob in objects:

# Selection
for ob in bpy.context.selected_objects:
    sce.vray.VRayBake.bake_node = ob.name
    sce.vray.SettingsOutput.img_file = "bake_%s"%(ob.name)

    bpy.ops.vray.render()

the problem is vray opens 2 windows to bake, but renders 2 times only the 1st object (cube).

it's possible to fix?
thank you in advance!

Re: Vray multibake textures

Set

sce.vray.exporter.wait = True

and it will wait until render end.

So it'll be like:

import bpy

sce = bpy.context.scene

# Enable autosave
sce.vray.exporter.auto_save_render = True
sce.vray.SettingsOutput.img_dir = "//bake/"

# Enable Bake
sce.vray.VRayBake.use = True

# Wait until render end
sce.vray.exporter.wait = True

# Selection
for ob in bpy.context.selected_objects:
    sce.vray.VRayBake.bake_node = ob.name
    sce.vray.SettingsOutput.img_file = "bake_%s"%(ob.name)

    bpy.ops.vray.render()

# Restore settings
sce.vray.VRayBake.use  = False
sce.vray.exporter.wait = False

Re: Vray multibake textures

thank you alot!

that's works but still not perfect because it start to render but when finished to start the new bake needs i close manually the vray frame buffer.
how can tell vray to close the process and start with other automatically?

thanks in advance!

sce.vray.exporter.autoclose = True

Re: Vray multibake textures

Thank you very much bdancer, you solved our problem

i really appreciated your help, your exporter is just awesome!

if i can i would ask you another hint about the baking textures with vray,

atm the only way to bake textures with vray is on individual objects, my question is:
would be possible bake by materials and not by objects?

for example a room with many materials multi bake by materials?

thanks

Re: Vray multibake textures

I guess may be you could just collect objects by materials, not sure if its possible to bake just material.
Here is an example with UI and operator stuff http://www.pasteall.org/40352/python you will just need to add some of the baking code.

Hi bdancer thank you alot for your help!

The first solution about bake objects works perfectl!

Unfortunatly we are not scripters so the one for materials we tried to complete the script u provided in pasteall.org but neither start the rendering, so please could you write the script with also the bake part?

Thank you again for your work

After run there will be a panel in Scene buttons called "Bake Tools" you'll find all stuff there.
Have fun! =)

Re: Vray multibake textures

I really liked the "bake by selection" script. I filled in the gaps and use the version below.

However, this locks Blender until the renderings are finished. I could use two instances of Blender to keep working, but is there a way to get around this?

import bpy

sce = bpy.context.scene

# Enable autosave
sce.vray.exporter.auto_save_render = True
sce.vray.SettingsOutput.img_dir = "//bake/"

# Enable Bake
sce.vray.VRayBake.use = True

# Wait until render end
sce.vray.exporter.wait = True

# Autoclose
sce.vray.exporter.autoclose = True

# Selection
for ob in bpy.context.selected_objects:
    sce.vray.VRayBake.bake_node = ob.name
    sce.vray.SettingsOutput.img_file = "bake_%s"%(ob.name)

    bpy.ops.vray.render()

# Restore settings
sce.vray.VRayBake.use  = False
sce.vray.exporter.wait = False
sce.vray.exporter.autoclose = False
