I'm working with Unity and C# making a platform game, i mostly used cubes/boxes of different scales to build the level and now i have to apply the texture, i played with the tiling but the texture obviously stretches to apply on different objects, making a different material for each object is too much, I heard that I should use shaders but I've never worked with them. Can anyone help me write a shader that can modify the tiling based on the size of the object? Thanks to everyone.

Is it possible that Sprite Renderer in a HoloLens2 Unity Project, which are masked via a SpriteMask are only visible on one eye in the final HoloLens2 build (UWP via VisualStudio2019 deployed on HoloLens2 device).
I also experienced the same behaviour on elements which are masked with a StencilShader.
I am using a 24-bit depth buffer for my unity project if that helps, otherways the StencilShader wouldn´t work.
To display certain objects to one eye, for different rendering configurations, different ways need to be used.
With MultiPass, you should be able to set a camera to render to only one eye(Camera component -> Output-> Target Eye), so doing per eye stuff is super easy. With Stereo Instancing, you can draw in Shader but you will need to multiply the projection matrix of the current eye.
I've decided to use Minecraft like characters in my small game since I do not know how to make 3d models (nor I want to learn how to do such thing in the near future).
However the task now seem a little harder than expected:
I've tried looking in the asset store for prefabs to use but without success.
So, I've decided to try and make a model on blender(by not knowing a thing about non parametric 3d modeling, my knowledge of blender is extremely limited) and import it into my unity game.
And surprisingly, I managed to create the model using McPrep, export it and import it into unity maintaining objects that drive the bones (the output is a bit messy but I think I can manage to clean it up a little).
However the imported version does not have any skin and appears in a gray shade.
Turns out that the output does not keep materials/textures with it!
I've tried getting the texture used by blender and it returns the same skin I fed into mcprep so, by using the same skin, I've tried creating a material with it by getting the .png and using it as texture in a unlit texture material.
However, the result is a bit messy as shown here (left is Blender, right is Unity):
How may I make the texture on unity3d be better and right? (I've heard there is a way using a C# script but I really don't know what it is nor how to do it)
EDIT:
Thanks for the answers before, I did set the filter to point obtaining the texture to be a bit better. However the part that should be transparent is displayed in black on top of the other part (I think).
The image on the right is only filter point and the one on the left is point + alpha is transparency and the transparent shader using unlit transparent
ANSWER FOUND:
As Bart said, make sure the textures' Filter Mode is set to Point, but additionally:
Minecraft player characters are made of 2 layers, the second layer usually has lots of transparency and is used for clothing or other relief detail. So you need to use a transparency-capable shader on your material in Unity.
You're running into a filtering issue. In your case you want no filtering to happen. So select your texture, and in the inspector change the import settings so that your "Filter Mode" is set to "Point". In this case it will do no filtering of the input and your large pixels should appear sharp as you want.
I'm having trouble figuring out how to light up large area(s) of sprites in Unity 2D. My previous knowledge on Unity's lighting is zero.
I first tried using a large amount of point lights and using the "Sprites/Diffuse" material, but about only five would actually render at a time, so I guess there's a limit on that.
Then I tried putting in an area light. That didn't do anything, so that's when I started doing research about baked lighting on sprites (and baked lighting in general). I found stuff like this but I couldn't get it to work either because it's outdated or because I don't know what I'm doing. Other answers I've come across seem to assume that the reader knows anything about lighting in Unity in the first place which, to be honest, I don't. Unity's documentation website had some information on it, but no tutorials that go into how to set up baked lighting.
I've tried a bunch of different combinations of materials (like using the "Standard" shader for the sprites instead of "Sprites/Diffuse", emission, ect.) and I enabled "Baked Global Illumination" in Lighting>Settings.
If baked lighting isn't possible on sprites (or isn't worth the trouble), what are the alternatives?
Edit: I made sure not to have the lights pointing the wrong direction, and I do realise that Unity2D is just like painting onto a piece of paper in Unity3D. I was able to get point lights to work, but only a few at a time. I don't need to do the entire screen at once, I need to do a large specific area at once.
some tips...
working with sprites your in 2d... when you add a light, switch to 3d mode, and rotate to make sure your light is pointed at your objects, and oriented so as not to be on the same plane, or level with them, as this will cast all the light behind them.
if your trying to light up everything on the screen(in camera) attach an area light to the camera at the cameras position, point it where the camera points, and then in the inspector on the right, you can change its variables. intensity, range, width, height etc.

For some reason, I never even thought about going into the asset store. I found this for free, and it looks like it will work: Light2D.
I am working on a VR app with Unity3d and I am making the scene rendering with Unity but I cannot achieve good image quality. Is it possible to import a full baked render from Maya, 3ds ( for example an .fbx ) with all the lightning and shading so that I can only work with Unity with the interactions ?
I need to get the highest image quality so I make it as realistic as possible.
Shaders will always be different, but in case your lighting conditions don't change, you can fully bake the result as albedo, and use unlit shader to just pass through the result. This will not work as expected if you want to move/rotate the resulting objects, however it might work for environments.
Have in mind that unlike max/maya, unity renders in realtime, in milliseconds per frame, not minutes per frame, so there are certain tradeoffs that are made to ensure speed, the reuslts will never be identical (as they are not identical between offline renderers).
Its probably best to just learn to use Unity shaders to its full, just as you had to learn max/maya.
you can bake lighting in unity3d too, which can give decent results
I am working on game in unity in which i need some images to be placed on terrain as in the attached image yellow arrows and "P in blue circle" are rendered on surface in unity.
Any idea or method will be appreciated.
There's no built-in support for decals in Unity. You could just create separate gameObjects with transparent texture and place them above the terrain here, or use one of several packages for decals in Unity Asset Store, like this one. (I have only briefly tried it and can't say anything about it's quality).
I know it's an old topic - but for those who are still not satisfied:
I would recommend using Easy Decal.
It's a very powerful decal projector. It's easy to use and you can stick decals also on uneven surfaces like bumpy terrains.
You could try putting a plane with the texture aligned with the surface normal slightly above the surface. Or you could try an extension that does decals for you. This is what i found:
Decal System for Unity3D
As previously mentioned Easy decal is a good choice. It's easy to use, has extensive fuctionalities and you'll get a lot for your money. But if you need skinned decals there's no way around Decal System Pro by Edelweiss interactive. It's more expensive, but beside the skinned mesh support it also supports texture atlases which saves you draw calls.
