Photogrammetry: Software to modify/correct details in 3D objects - unity3d

I started to work with 123D Catch and Blender a while ago. I made some photos and created 3D object in 123D Catch. Next step is to put it into Unity.
But before it I need to correct some details (some edges have inappropriate shape, colour is missed in some places etc).
I tried to import this 3D object into blender but I couldn't upload texture automatically (I watched some tutorials about mapping, but exaples are easy and my object has complicated construction).
Can anyone reccomend me a software where I can correct basic stuff like egdes, shape or colour easly?
Thank you a lot.

When downloading the models the textures are included as 1 or more
image files.
you can edit them in any image manipulation software (e.g. Gimp or Photoshop)
When opening the model in blender
make shure that you use file>import>obj
and turn on textured mode :
Mapping is not neccesary as the UVs are contained in the model alredy.
After editing the shape you can
export the model via file>export>obj or just drag the .blend file into your assets and let Unity convert it automtically.
Before you use your model in unity you should consider reducing its geometry/detail as the generated models can be very high poly.
For that purpose, I can recommend "Meshlab"

AR Foundation face mesh for creating custom assets

I'm looking for either a 3D model or an image file over which I can apply my own custom graphical elements, such as eyeliner or lipstick.
In the ARCore docs, the solution to this issue is very well described. You can get either an FBX file or a PSD template, over which you place your own elements.
From what I can tell, the principle of ARCore and ARKit are very much the same - there's a standard face mesh which gets contorted to the shape of a detected face, however, I'm unable to find any such materials using Google.
Just use the same face model and use slightly larger copies of it for the makeup. No one is going to get close enough to see how thick its caked on, because all the polys would start disappearing anyway...

How to make a mesh editable for unity3D

well i have a 3D model of the human digestive system I found it in the internet, this model is :
a .obj file
if a fixed model (not dynamic)
here is screenshot of the model :
so what I want is to make this model editable on the game like for example
the user of the game can cut the intestine and suture it (so in other way making a surgery)
I'm not sure if it is possible or i should create a new model from scratch to do that
Note :
I'm working with unity3D for creating the game and I'm trying to adapte the model with what I want using blender and cinema 4D so whatever the tool needed to do it i will use it
You should first go through these two pages to understand how meshes work and how you can manipulate them in Unity.
Using the Mesh Class
Mesh
Unity isn't a mesh editor, it's an engine. You can write your own scripts to add the functionalities you need, or also there are some pre-made assets that do some mesh editing available in the Asset Store.
The best approach is to remodel all in small fragments so you can easily cut the pieces you want.

How to export fbx with textures from Unity?

I have downloaded a Unity asset which included lots of 3d models with textures/materials etc.
I wanted to share one of those objects with an artist, so that they can create a new model on top of that model, so I exported the fbx from Unity using one of the Unity fbx exporter assets.
However, the model was exported without any textures and so it looked pretty much white as a whole. Therefore, the artist cannot really work on a model that includes textures and also send me back the finished work with those textures.
I am wondering, is there a way to actually export everything with the fbx
from Unity ? Thanks !
Assign your material in the source package, make sure there is a baked texture in the diffuse slot
Assign your other baked textures to the spec, normal and others
Check embed textures at export
Check 'import materials: by material name' is selected for your imported model (in the inspector)
Where possible use a portable file format like FBX and follow these guidelines.

Importing blender textured objects into unity

I am able to get this particular textured model from a 360 camera in blender. Blender Image
However, how do i get this .obj model into unity? I am only able to get the shaded version of it, not the textured version. Unity Image
When you export the .obj you should have a .mtl which contains the material data and texture mapping. Make sure when importing into unity (and exporting from blender) the file is generated and read.
Check your blender material properties and the individual texture properties. you should try to combine all materials into a single material so that its easier to reconfigure the textures in unity.
Once imported into unity, check the material settings and check if you need to reference the texture files again, most often when importing exporting .obj, the texture path gets lost so you must re-reference it in the target software. Sometimes it is also necessary to re-assign the materials themselves.
Also check your rendering options in unity, you may just be seeing it untextured in the unity viewport. (on the top left corner it says shaded, try changing it to textured or some other option)
You may as well try to use other mutually supported file types, like .3DS which do not use a separate material file, or check for blender add-ons that can export with all necessary settings for Unity.
Finally, your model is way too complex, it is raw data from a 3D scanner or ripper, I suggest you remake it so that you have manual control over each face and texture. (or at least for practice of doing the export-import operation).
More details like pictures of your material settings of both blender and unity would help in assisting you further.

Texture from Blender doesn't appear in Unity 3D

I've searched endlessly for an answer to this question. However, I have created a model in Blender and export it as a .FBX directly into Unity. But the textures I have applied in Blender do not render in Unity (Even in the preview screen). I have UV Unwrapped the model, and created a custom texture pattern to suit. I've inserted the textures into Unity, however this just loads them how Unity feels, not how I'd like it to look.
I've attempted to add it as a .blend file, but Blender crashes, and it fails to convert to an .fbx file in Unity. The model is of a wall, with 3 doorways, and 3 doors. The wall has its own texture, and the doors all have the same texture. (I'd upload images but haven't earnt enough rep).
Is there a simple solution? Or am I over looking the whole process and missing something important out?
after you UV unwrapped your model you save the uv in a file in blender you should apply that file as a texture to your model in unity and you will be done,tell me if you have already done that. Here are useful tutorials.
I had better luck exporting it as a wavefront object. Under transform select Path Mode: Copy and you should get your materials.
