MIRACO loss of detail: Sculpture and Life casts

I’m a newcomer to 3D scanning and printing, currently using the Miraco pro as my first scanner. My goal is to accurately capture details such as skin folds, wrinkles, and clay textures when scanning sculptures, body casts, and people. Despite having the settings on “advanced,” I’m experiencing notable detail loss, with the Miraco seemingly smoothing over these intricate features.

I’m seeking advice on optimizing settings or learning any tricks to enhance detail capture with the Miraco, especially considering that my sculptures range from life-size figures/busts to 50% life size.

Your guidance is highly appreciated!

If you edit scans on PC look into this.

On Miraco itself it is the same, but because of battery draw I prefere editing on pc.
For maximal details use near mode, keep optimal scanning distance and avoid IR-light sources like sunlight.

you also might consider using single-shot mode:

Thank you Ivan. I’ll be following your advice.

Hi @ESculptor for the best result , scan the objects in Near mode , do not process the scan on Miraco , import it to Revo Scan 5.4.1 via WiFi or USB

After importing , go to fusing tab and choice Advance mode set at 0.20 or 0.19 and process , after your point cloud is ready , please clean it with functions like lose point and overlapping points tools …

After that mesh it at the same Grid as it was fused , if you fused at 0.2 make sure the meshing grid is at 0.20

If will ensure that you have best results regarding details .
I specialize in human bidy, cast and figure scanning . This method should give you optimal result .

Also remember to keep the excellent distance while scanning , do not use the One click function for processing , also Textured model have lower resolutions than just meshed , if the mesh is important , always export it when the Rendering tab is set at Meshed and not at Textured …

It is an easy step to get super results
It would be great if you can share some scan and the original for comparison , I will tell you more about … it is hard to guess your results just from words and what level your archived so far .

Thank you so much for this info. I will follow through with your advice on some test scans today. I’ll report back with some images.
Thanks!

Hi again,
When I merge a multi-part scan and then mesh the new model, it loses a lot of detail and resolution, compared to when I do not merge the parts. How can I avoid this problem?
Thanks very much!

You only can lose details if you meshed it at lower resolution . Please mesh it at the same Grid level as you fused the single scans before merging .

Do you have screenshots?

It doesn’t seem to allow me to adjust the resolution under the “mesh” options to the right.


Here’s the raw model:

Here’s the fused model, before I mesh it:

Hi @ESculptor

Sometimes it do not allow to mesh exactly with the grid settings corresponding to fusing settings .

I ask you for screenshot so I can see the info of the fused data , not the model

One click edit is not important here .
I need to see the amount of points generated after fusing …

You can easy use 0.20 Advanced mode fusing with this one .

FusionPoints

I fused it under advanced/ point distance 0.19.

Ok the number is slightly too high for the meshing level . It got over the limits .

Try to use point cloud simplify and use the geometric mode .

How you got this point cloud size anyway with MIRACO ?

do you use the latest RS V5.4.2 version maybe ?

This scan should be not bigger than 1.5-2 millions only at the settings … so there is some bug in the fusing function .

I use version RS 5.4.1. I tried using geometric mode. I fused, merged, and meshed. Still loss of detail. Instead of merging in RS I imported the individual parts into ZBrush and merged them there without losing detail/res. It’s more difficult because I have to merge it manually by eye…

Hi @ESculptor

It is not lose of details , it is just maximum the meshing allows what is level 7 .

Try Cloud Compare , you can mesh it at whatever you like .

Is Cloud Compare a program that will merge individual parts?
Thanks

Yes you can merge too

Here is my tutorial of merging multiple scans in CC

Thank you.

New issue: I downloaded a software update. Then I imported a new project from the Miraco. Now, I cannot open the project. Do you have a solution?
Thanks

What software update ?
Check if the project is empty or not , Revo Scan creates lots of empty projects , check the size .

How you imported, WiFi, USB ?

You can send me the project to putvmail@gmail.com zipped as a link , I can check for you

For the details you are trying to get, use single shot mode, near mode and make sure you have as much control over lighting as possible. Also, many might disagree with me on this, but sending to a PC for postprocessing usually gets me better details. It may depend on your PC, though. I have a pretty graphics intensive custom desktop. Business class laptops might not yield too much

Hi @JSchwam the problem was not about getting details , the details was there and it was processed on computer .

After 3 .months of testing , processing meshed on MIRACO or high end PC giving you the same results .

The problem here is , that the meshing settings level depends of the fused value of the total scan .
It is recommended to remove all not usable volume parts direct under RAW edit before fusing , it will increase the quality in meshing ( the grud level )

The fused scan looks just perfect , but over 7 millions of points do not mesh well in Revi Scan and the final mesh is downgrading to lower level .

The major function of Revo Scan is to deliver the perfect point cloud according to the specs of the hardware , anything after is not much important or huge priority .

If you need very high level mesh use Mesh lab or Cloud Compare if you can deal easy with 40-50 million meshes and your computer have enough power of the processor and RAM .
