[MtoA]Rendering to Texture

[Anonymous]

hello everyone,

I want to write a python-script that batch renders shaders to textures using render to texture from Arnold, but I'm already stuck at step one.

cmds.arnoldRenderToTexture("Path")

Produces an error "No geometry selected" no matter how many Meshes I have selected in the scene. cmds.ls(sl=1) confirms, that I have selected something. I have inspected the python-file for render to texture and found the line, where the script checks for selected objects.

For reference:

[...]

selList = cmds.ls(sl=1)

        if (len(selList) == 0):
            cmds.confirmDialog( title='Render To Texture', message='No Geometry Selected', button=['Ok'], defaultButton='Ok', cancelButton='Ok', dismissString='Ok' )
            return False

        cmds.arnoldRenderToTexture(folder=outFolder, shader=shader, resolution=resolution, aa_samples=aa_sampling, filter=filter_type, filter_width=filter_width, all_udims=all_udims, udims=udims, uv_set=uv_set, normal_offset=normalOffset, enable_aovs=enableAovs, extend_edges=extendEdges,u_start=uStart, u_scale=uScale, v_start=vStart, v_scale=vScale, sequence= useSequence, frame_start=frameStart, frame_end=frameEnd, frame_step=frameStep, frame_padding=framePadding)

[...]

The error should not appear, as long as I have selected something. But it does.

Any help is much appreciated, thank you. 

Btw. Doing the same manually with the Arnold Utilities works just fine.

Was able to solve it myself. It appears, that the function has to be called as

cmds.arnoldRenderToTexture(folder=path)

and for some reason, if the folder argument is not explicitly stated it will produce the above error. Strange. There go 2 hours of my life.

Your two hours were not wasted good sir, it was quite useful to me.
