Efficient Workflow for glossy material

Development Asset Creation

Hi,

We are mainly scanning shoes and action figures and want the output 3d model to LOOK as real as possible.
(Mesh doesn’t have to be exact, but it has to look real)
We basically want to minimize human labor on post processing after CR.

As you may also know there is below 3 issues while scanning glossy surface.
1] Mesh create holes
2] Texture color distorted (ex) glossy black is captured as matt gray)
3] Glossiness of material is not captured

So, what we have to do is
1] fill the holes in Zbrush
2] divide the mesh apart from main
3] Add a thin shell
4] Apply material that is glossy and controls the glossiness

This process is quite a labor consuming.
Is there any more efficient way?

When I look at some articles, there is some approach to capture specular normal maps automatically.
Is there or will there be some features to capture glossy material automatically in CR?

Regards,
Justin

Hi Justin
Please take a look here at the James Busby Ten 24’s tutorial on this matter

Yes, we have looked at the blog by James Busby Ten24 already.
So I guess this is the best flow so far right?
Major Problem for this flow is that CR takes care of the Mesh only.
Texture and Material should be reconstructed from manual process, which is quite time-consuming.
Is there anyway to automize this?

In some academic paper, there is some way to capture specular normal automatically.
Is there any future plan for this?

Justin

Hi Justin
regarding the white papers, it takes “few” years to get from labs to some real world useful solution.
The material settings need to be set by hand in an external application, where you can change material parameters as it is the easiest and fastest way to do it.

I see. Thanks for your advice.
1] Is there a way to capture image sets twice ( one with original object, one with matt sprayed as Ten24 example) and use one set only for Mesh, another set for texture coloring?
2] Otherwise, is it possible to construct a Mesh using Laser Scanner and color with image sets?
