Spritesheet creator/importer for unity3d - unity3d

I am currently developing a 2d game for android using Unity3d , but i am wondering if is there any free sprite sheet creator software that is compatible with unity3d without the extra code to be written , i've tried texture packer with there plugin for unity and it work great but this software is paid and i can not afford it right now ,
i also tried Sprite Sheet Packer but when i import the sprite sheet into unity and trim the sprites in the editor the animation does not work properly due to the fact that unity did not know the pivot point and the exact information of the sprite inside the created sprite sheet,
Does anyone know some useful free software that i can use or some unity plugin that can serve this problem ?

I personally always used TexturePacker (then when I moved to Unity, NGUI does the work for me), so this is a recommendation from a friend:
http://renderhjs.net/shoebox/
A quick test showed that it made a PNG and accompanying XML file with the image data inside. Seems pretty simple.

This question still actual in 2017. So this is my approach:
1) Get xml file with coordinates from your editor. I use DarkFunction sprite editor for fast and smart creation of coordinates. It's free and pretty clever to do lots of jobs automatically.
2) Install this asset from asset store, it's free.
3) Tweak the TextureAtlasSlicer.cs file from the installed asset to correspond to your xml format. You have to do this only once.
That's it.

Unity 2018: 2D Object - SpriteMesh

Ok, so I have looked around the internet but I cannot find the sprite mesh. I should be able to right click my sprite> 2D Object> SpriteMesh.
Problem is that I don't see the option "SpriteMesh" anywhere.
Here's the deal. I created a bunch of 2D pieces for a character: head, body, two arms, two legs, two hands, and two feet. I imported the sprite as a PNG file and changed SpriteMode to multiple. I used the Sprite Editor to slice the char into pieces automatically. There's also nothing inside of the sprite editor that allows me to rig bones either.
Now I need to Rig the toon with bones and skin. However, I cannot find a way to do this. Watching a few tutorials, the guy adds a SpriteMesh to each of the parts. However, when I try to do this, the option just doesn't exist. I see SpriteMask but no SpriteMesh.
I'm using Unity 2018.2.18f1.
I have zero experience in animations like this. Normally I create a player/enemy without legs/arms. So they just float and I use the animation tab to change size/shape to insinuate movement. However, I'd like to take this next step and make the game look better.
How can I rig my toon? What steps do I need to follow?
All help is appreciated!
I guess you want to use the new 2D Features from Unity, if you want to rig your 2D Character.
I'm using Unity 2018.2.18f1.
You need to use Unity 2018.3 or later to use these tools.
I suggest you to use Unity Hub to download multiples versions and Beta versions.
There is a really nice video from Brackeys about this subject also.
When you have the 2018.3 or later version installed, open your project and go to the Window/Package Manager window, you need to install these packages :
I don't think you need the 2D Pixel Perfect but it's always nice to have.

how to open prefab brush window in unity 2017.1.1f1?

I am a complete beginner in unity 3d and I rely on youtube and other sources to learn unity. I will get to the point.. I am currently watching this tutorial #19:35 he opened a window called Prefab Brush but it is not available in mine which is Unity 2017.1.1f1. I believe in the future I might need this prefab brush, so I would like to ask some help.
Image here
Prefab Brush is a plugin from the Assetstore. It's was free at the time that video was made but the publisher decided to make it not free anymore. It cost only $2.99.
If you don't way to pay for that then use GeoPainter which is free and very similar to Prefab Brush. You can get GeoPainter here.

3d FBX file import into Unity not working as expected

I am interested in building virtual reality applications and I am at beginner level.
I imported a FBX file of Airplane and imported it in Unity,
Upon linking the animation in Unity and building it onto my Mobile, I see a 2D version of the model. How should I convert it into virtual reality application.
Below is a snalshot of the file. The aiation is also fairly simple, one plane takes off and flies for sometime before landing.
Below is a snapshot of the Game Console
So inshort the question is how do I convert this into a 3D mode so that I can use it as a virtual reality Application.
Thank you
That is 3D mode.
Making a VR application isn't done at the push of a button
Start here:

It seems like you are a new Unity user. If so do this first:
Depending on what you want to do in your application you should look into the Unity Documentation and read about:
Basics
Cameras
Creating Gameplay
Animation
If you at some point feel you don't understand these links, you may need to take another step back and start off by checking out the official tutorials
Just save your .blend file in the Unity's Assets folder.

OCR with Unity3d

I would like to implement a letter detection feature for my "guess the drawing" game in Unity, that would detect if someone draws a letter and I would count it as cheating. So people would only be able to draw the word requested as pictures and would not draw the letters that create word itself.
I would like to know what is your opinion and what technology can I use for this task in Unity3d. Thanks in advance.
Vuforia is best pick for your requirement.
You can download vuforia SDK for unity from below link.
https://developer.vuforia.com/downloads/sdk
Steps need to be followed:
1.Download SDK for unity.
2.Draw the patters which you want as answers in any of tools like paint or photoshop and take screenshots of them.
3.Remove main camera and add AR camera in prefabs folder of vuforia library
4.Drag and drop image targets to your project and add the screenshots you have taken
5.Now implement code to broadcast message if image target is detected.
6.Use this broadcast message to implement post game logic.
There is so much to learn about image recognition and Vuforia, adding image targets and all require few additional steps, You can go through the tutorials for better understanding on how to use Vuforia SDK.

What is the best software for creating OpenGL ES models and textures?

What is best software for creating models , textures etc... for iphone development.
From simplest to more complex programs.
First thing that comes to my mind is blender , but I'm curious what everybody else is using and their opinions.
Blender is a very good issue for your needs.
It's a very complete solution. Just take your time to learn it step by step. You'll get some great tutorials on the website.
Agreed! I found a tutorial about 3D programming mentioning Blender as a free tool. It was SO daunting to use at first, and I still haven't even figured out most of what it can do. However, I can now build and export the needed geometries for my applications.
Tips:
Use a 3 button mouse (RMB:Selects a vertice, edge or face; MMB Rotates the view camera)
'A' selects or deselects all
'X' deletes anything selected (prompts you first)
'B' Bounding Box Selection Mode
'E' Extrude selected things
For creating textures, I use Adobe's Illustrator, Photoshop and Fireworks, and then import the image into Blender. There is also a texture paint mode in Blender as well.
I tried Cheetah 3d , it looks decent and it exports directly to header files.
I will definitely try blender , but it seems overwhelming and i am not sure do i need to loose to much time on getting to know how to work in blender.
On other hand i was trying out cheetah 3d and i figured out most of the staff in couple of hours.
