Could I import both high-poly and retopo'ed low-poly mesh together?

[raincole]

I know it's an unsual workflow, but could I import both high-poly mesh and low-poly mesh into 3DCoat, and keep sculpt it with "Conform Retopo" option?

My use case:

I bought a model from a third-party, which is a ZBrush file with subdivisions. I know 3DCoat doesn't have subdivs (at least not the same as Zbrush), and I'd like to furthur sculpt it. I'm more comfortable with 3DCoat's sculpt tool than ZBrush's, so I'd like to sculpt in 3DCoat. I've export the highest and lowest subdiv from ZBrush as 2 .obj files.

What now? How to import the high-poly as Sculpt mesh, but the low-poly as Retopo mesh?

Its a trial an error, very personal task.

Depending on the type of model, the density of the retopology, the type of sculpting... there are many variables to give a can/cannot answer.

This video demonstrates an update to the "Conform Retopo Mesh" feature in 3D Coat's Sculpt workspace, which allows the user to see the Retopo Mesh (in the Sculpt Workspace) while making large scale edits with the Pose, Move, or Transform tool.

I don't see why this is a hard-to-answer question. Maybe I worded it badly.

Ignore all the Zbrush stull. Say I have two .obj files. One high-poly and one low-poly. How could I import one as retopo mesh and one as sculpt mesh, and make 3Dcoat realize that they're connected (so "Conform Retopo" feature works?)

It's a simple question with just two .obj files. No variables now.

In your video, the sculpt mesh and the retopo mesh are alreay there, in 3DCoat. My question is how to make them "be there" when they're just two .obj files.

On Sculpt Room: use File > Import > Import for Sculpt/Vertex Painting/Reference

on Retopo room: Model > Import mesh

Hope it help

I have the same question and have been searching the internet for the answer. I have not found an answer.  Have you found the answer?

Try this - ScreenCaptureProject1065.mkv

As long as both models occupy the same xyz coordinates it is not hard to do.

There are a few ways to this, Oleg gave you one. Here is another.

In the sculpt room choose the import tool (left toolbar under Objects) 

Select Import w/o  Voxelization  then use the Open the Mesh command. Select your hi-poly model. Your model will be placed in Surface mode.

Click on apply and then choose a brush to finalize the import. The reason it does not completely finalized the model after pressing apply is if you want more than one copy of the mesh. Also do not scale the model. It will come in its original scale. If the model is all quads it will just be triangulated.

Switch to the retopo room.

Under the Mesh menu at the top, Choose Import. Import your low polygon model. 

Your low polygon model will appear in the retopo room workspace. Press the Enter key to confirm the import. 

If your models have the same xyz coordinates, then the low polygon retopo mesh will be at the correct location. 

I normally have auto snap off as 3DC will snap the low polygons vertices to the high poly model. It really depends upon the model if you want Auto Snap on or off. You can try both ways to see what works better for your low polygon model.

Conform Retopo Mesh is available to you now in the Sculpt Room.

Both models high and low must have the same xyz coordinates as mentioned before.
