[Solved] How can I hide those polygons while retopology

[Yousung]

 

When i working on retopology

sometimes i can see the topology on the back, so it is a bother me when working.

I tried adjusting the Z-Bias ans Opacity value, but it doesn't seem to work out perfectly.

Is there any option to hide that face or something?

Hello

Try turning off Backface culling

[Yousung]

Thanks for the answer @Carlosan !  

Unfortunately, that option did not solve it.

In addition to the problem of seeing the back of the polygon, there were various complex problems.
----------------------------
1. Clipping problem in Perspect view
2. The problem of overlapping surrounding edges
3. Zoom-in no longer works in Othographic view (maximum zoom-in limit)
4. Retopology-Unable to split the middle of the edge of the Add/Split tool (snapped to surrounding vertices)
----------------------------

To solve this, I searched all over the forum.

All of these issues are now resolved, and I plan to post them after work.

To conclude...

My object was very small compared to the scene scale.

(The object was worked in meter units in 3dsMax.)

I've documented the process of solving this from a newbie's point of view.

As I got help from the forum post, I hope other newbies will get hints when they see this post later through search.

Please understand if it is difficult to read because it was written without a translator

 

This is the object visible at SceneScale = 1.

The object is about 10M when viewed in 3dsMax.

 

When I first brought modeling from outside, I wanted to keep the size and position as it is, so I increased the resolution value of SculptTree and clicked [Apply] as it is.

At this point it seems the problems are starting to snowball.

 

After importing the data, I proceeded to clean up the faces (there were many holes or gaps because of the scanned data) and the topology.

Then I ran into several problems.

Multiple problems encountered while working with object topology

1. During topology work, the polygon at the back is visible through the high polygon (The first question I posted last time)
2. Clipped in perspective view
3. Surrounding edges overlap
4. No more zoom-in in Othgraphic view
5. Add/Split tool does not split the center of the edge during retopology (it snaps to the surrounding vertex)

When I first saw these problems, I was able to ignore them and continue working on them. As the topology cleanup progressed, it started to get harder.

So, to solve this, I searched the forum posts and saw one post.

• Camera looks inside object when it's close, instead on surface (Link / By Alex_3DC )
• [Solved] Near camera clipping (Link / By ajz3d)

I checked some of the same problem (Clipping & Zoom limit) in this topic, and here I found that the functions of SceneScale and the objects of workers are small (small objects, people... much smaller than my objects...).

 

The first time I tried raising and lowering the value of SceneScale

Tried turning 3DCoat off and on, but it didn't fix the problem with the viewport.

 

The clipping problem was solved by increasing the size with the function to increase the size of the voxel modeling in Sculptroom

('Increase Object 2X', which appears when you right-click in SculptTree).

 

However, when exporting, the size is completely different from the first external tool sent,

and unlike SculptRoom, RetopoRoom did not show the ability to increase the size.

(Or maybe I couldn't find it because I don't know much about the tool ️)

 

Until this time, I thought it would come out by right-clicking like SculptRoom

I started searching the forum again to find out how to size the retopo.

 

I have seen a forum post that is crucial to solving the problem.

• Import Retopo Mesh size (Link / By popwfx)

[TimmyZDesign]

"Then scale up the model (using the scale gizmo) to the size you want to have the model displayed in your viewport."

 

I searched for the article while thinking about resizing the retopo, but I came up with another solution that was completely unexpected.

 

After reading the article, I thought I misunderstood the first time I imported the modeling

(because I just thought that if you adjust the scale during import, the size of course changes..)

I built a Cube with 3dsMax and started testing it.

 

Here is a 10M cube made by 3dsmax.

 

When importing the cube, I tried to adjust the size.

(I don't know why, but the grid size has changed....I'll find this later )

Scenescale is also different from the previous default (1.0000...).

Exported to 3dsmax again.

 

Perfect! The number on the right is the SceneScale to distinguish it.

I thought that this would allow me to fix my object

 

 

Go back to the original work... Export Scene

(Same thing in: File-Export-Export Scene)

 

 

 

I am creating a new 3DCoat and trying to import it....

There was an Export Scene, so I thought there was an Import Scene too, but that wasn't...

By the way, there are so many types of Imports!!!!

I don't know what all of them are

Are only the functions that people use often painted in yellow?

I have to study step by step...

Anyway, let’s import it with Import Mesh for Voxelization.

 

 

When importing, an error like this appeared

I couldn't see it while organizing my notes again this time...

When solving the problem

 

• [Solved] "out of memory" exception when opening file (Link / By Gian-Reto)
• Increase virtual memory - Help? (Link / By Dezzlor)

I saw these topics and it was resolved by unchecking [Show Voxels in Paint Room], mentioned by Carlosan, and then exporting again.

 

I didn't take a separate screenshot, but at the time, the size of the exported Scene object was dramatically reduced. (hurray!)

Maybe I've been doing some bake tests before, and I wondered if something had affected.

I don't know anything, I just guess..

I'll have to look into those options separately.

 

Now, after loading the scene, I went back to the Retopo Room to see if the retopology problem was resolved.

 

Where is my topology?

I guess Scene Export wasn't something that put everything I was thinking of.

It seems that it can be export from the Retopo Room, so go back to the original file.

 

 

File-Export Retopo Object

or

Retopo-Export ~~

I think you can do whatever you want.

I am moving it all at once

Sent to File-Export Retopo Object.

 

go back to the new scene

Import the file with Import-Import Retopo Mesh.

3DCoat thought i have a lot for polygon...

I just pressed OK.

 

 

Presse Apply...

I will bring it as is. I pressed No.

 

finally!

Moved to topology. It was confirmed that all UVsets were transferred normally.

Now I checked to see if all the problems were solved.

 

OK, everything is solved !

(The reason why UV is different is because Unwrap was not applied after fix)

Zoom-in works very well and the Add/Split tool splits well without vertex snapping.

 

Topology finish, UV, painting, etc. still remain, and I think that there will be another problem around that time, but I'm glad that I solved the problem now

 

I am hoping for some help from someone.

Oh! How can I put the title Solved??
