[Solved] Baking shaders problem

Recommended Posts

The voxel sculpting is made of different voxel objects, each with it's own material.

When baking into low poly model, there is material issues , i tried different outer and inner shell values, but it seems it's a bug with objects.

Can you share your Retopo Groups window ?

If you have four hi-polys and four low polys to bake, use this option

Suggestions

Modify the retopo mesh to follow exactly the geometry, some point are out of space.

Scale the whole scene a bit to get better results, almost 1000%, the model is very tiny to let the algorithm work better.

Hope this help

I scaled up the object, it's better but there is the same baking has artifacts between different voxel objects.

I had the same problem when importing one object made of multiple high res models, and trying to bake in one single retopo mesh.

Are you using latest version 4.8.31 ?

Try using another shaders, some dont give good results.

It does not work either

3D coat is not able to bake multiple Voxel Objects into one retopo object correctly.

There will be glitches.

If the images are what you want, they should all be booleaned together in one volume. An easy job with right click>Merge Visible. In Retopo, make seams to separate for painting.

When you merge visible you loose each voxel object materials, the boolean object result have only one material.

I guess 3D coat has never been designed to bake Voxel materials and separate volumes.

This is the same issue when you import a model from Zbrush made of many objects and try to bake to one object, there is baking bugs.

This is the baking in Xnormal, the baking two high poly object to one low poly retopo does not have seams problems.

3D coat makes errors baking on objects jonction.

The only workaround I could think of was restoring the materials in Paint. (Pretty fiddly:()

This is why i use Xnormal to bake normal maps for multi objects.

Not sure lot of people use 3D coat for complex baking otherwise this bug would have already been posted.
