It would be great if CC could export an applied animation to a character - as a complete Obj Sequence Currently, the nearest it can do is "export current pose" That would be a chore to do a 1000 frame animation mesh export manually. 💡 Could this be done via Python Scripting you think? Also, it would be nice to have the ability to "bake" current effects/lights into the texture to be exported with the OBJ. All atlased into separate PNG (Diffuse with light baked option. Normals...others) In Blender its called "cycles baking" or Render baking. The CC renderer is quite good - and the benefits are Iclone's native physics for cloth etc can be baked into an OBJ sequence meshes for further manipulation in many other software (blender, Element3D for Aftereffects...) Anyone else would like these features?

Sorry! I posted this under iClone8 wishful features. it needs to be under CC wishful features.

There is no essential difference between the CC and the iClone renderer, so this would indeed make more sense as an iClone features. Differences in rendering that users perceive are mainly due to differences in lighting, textures settings, etc.

You're right about the renderer / lighting Animagic. But I think only CC has export to OBJ? and so would probably be easier to implement a solution for OBJ sequence.
iclone has fbx, alembic and USD.
Being a non-coder, I'm still wondering if there's a way to achieve this via python scripting in CC.
The "cycles" like Render baking of textures with the current lighting/luts would be good to have then, all within CC.

@Victor.Soupday , using your mad python skillz, would it be possible to automate saving a sequence of OBJ meshes of an animation applied to a character in CC?
It just seems a painful way to be saving "poses as obj" for say a 1000 frame animation.
Thoughts?

I don't really see the point to this over an Fbx animation or an Alembic from iClone. But the following seems to work:
import RLPy
import os
from PySide2 import *
from shiboken2 import wrapInstance
def export_obj(avatar, path, with_materials = False):
options = RLPy.EExport3DFileOption__None
options = options | RLPy.EExport3DFileOption_RemoveHiddenMesh
options = options | RLPy.EExport3DFileOption_AllClothes
options = options | RLPy.EExport3DFileOption_BakeSubdivision
options = options | RLPy.EExport3DFileOption_AxisYUp
if with_materials:
options = options | RLPy.EExport3DFileOption_ExportMaterial
options = options | RLPy.EExport3DFileOption_ExportExtraMaterial
RLPy.RFileIO.ExportObjFile(avatar, path, options)
def frame_path(dir, name, index, ext):
return os.path.join(dir, name + "_" + "{:06d}".format(index) + ext)
def run_script():
avatars = RLPy.RScene.GetAvatars(RLPy.EAvatarType_All)
if avatars:
avatar = avatars[0]
file_path = RLPy.RUi.SaveFileDialog("Obj Files(*.obj)")
if file_path:
dir, file = os.path.split(file_path)
name, ext = os.path.splitext(file)
fps : RLPy.RFps = RLPy.RGlobal.GetFps()
startTime = RLPy.RGlobal.GetStartTime()
endTime = RLPy.RGlobal.GetEndTime()
startFrame = fps.GetFrameIndex(startTime)
endFrame = fps.GetFrameIndex(endTime)
time = fps.GetFrameTime(startTime)
RLPy.RGlobal.SetTime(time)
i = startFrame
print(f"Exporting frame: {i} with materials.")
export_obj(avatar, frame_path(dir, name, i, ext), with_materials = True)
for f in range(startFrame, endFrame + 1):
i += 1
time = fps.GetNextFrameTime(time)
RLPy.RGlobal.SetTime(time)
print(f"Exporting frame: {i}")
export_obj(avatar, frame_path(dir, name, i, ext), with_materials = False)

You can run the script from the script menu. It will ask for a save location and file name. Also, it's not fast. It takes about 3-4 seconds per frame to export, so a 1000 frame animation will take over an hour to export. (And probably take up over 10-20 GB of disk space) And... it won't do any physics, because it's not actually playing the animation.

Omg! Thank you so much. Can't wait to get home and try it this evening.
I understand what you say (regarding fbx being superior). This is so that it can be imported into software like After Effects (via Element 3d)
as well as a base for other manipulation in non-bone driven playback software (VFX visuals in VJ software etc,..)
I see what you say about no physics support :-( It would be nice to have it if there was a way to play the animation - freeze- then do the export then un-pause.
Also if the light/luts could be baked into a single texture... but that;s asking too much.
Many thanks for this. I'm sure others will find use for it too.
Will report back on how it works

P.s. will it also "triangulate" the Obj mesh, like the existing Obj single save does? This would be helpful. But, will try it first

Yes, it's triangulated.
Also depending on the Units of what you export it into, it may need scaling down by 1/100.
Only the first mesh is exported with materials, the others are exported without. Otherwise it would take 10x longer and be up to 50x bigger.
If you want materials on every frame you can alter the last line: with_materials = False to with_materials = True
