Unity transparent shader not working

Unity 5 introduced the Standard Shader A built-in shader for rendering real-world objects such as stone, wood, glass, plastic and metal. Supports a wide range of shader types and combinations. More info See in Glossary which replaces this shader A small script that contains the mathematical calculations and algorithms for calculating the Color of each pixel rendered, based on the lighting input and the Material configuration.

More info See in Glossary. Unity 5 introduced the Standard Shader which replaces this shader. This shader can make mesh The main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons.

More info See in Glossary geometry partially or fully transparent by reading the alpha channel of the main texture. In the alpha, 0 black is completely transparent while white is completely opaque. If your main texture does not have an alpha channel, the object will appear completely opaque.

Using transparent objects in your game can be tricky, as there are traditional graphical programming problems that can present sorting issues in your game.

The general rule is to be aware that there are some cases in which one transparent object may be drawn in front of another in an unusual way, especially if the objects are intersecting, enclose each other or are of very different sizes. For this reason, you should use transparent objects if you need them, and try not to let them become excessive.

You should also make your designer s aware that such sorting problems can occur, and have them prepare to change some design to work around these issues. This shader is Vertex-Litwhich is one of the simplest shaders. All lights shining on it are rendered in a single pass and calculated at vertices only. By default, the main camera in Unity renders its view to the screen. More info See in Glossary effects, such as light cookies, normal mapping, or shadows.

This shader is also much more sensitive to tesselation of the models. If you put a point light very close to a cube using this shader, the light will only be calculated at the corners. Pixel-lit shaders are much more effective at creating a nice round highlight, independent of tesselation. Generally, this shader is very cheap to render.

Publication Date: You can have as many tags as you like. Tags are basically key-value pairs. Inside a SubShader tags are used to determine rendering order and other parameters of a subshader.

Note that the following tags recognized by Unity must be inside SubShader section and not inside Pass! In addition to built-in tags recognized by Unity, you can use your own tags and query them using Material.

GetTag function. You can determine in which order your objects are drawn using the Queue tag. A Shader decides which render queue its objects belong to, this way any Transparent shaders make sure they are drawn after all opaque objects and so on. There are four pre-defined render queues, but there can be more queues in between the predefined ones. The predefined queues are:.

For special uses in-between queues can be used. Internally each queue is represented by integer index; Background isGeometry isAlphaTest isTransparent is and Overlay is If a shader uses a queue like this:.

This will make the object be rendered after all opaque objects, but before transparent objects, as render queue index will be geometry plus one. This is useful in situations where you want some objects be always drawn between other sets of objects. For example, in most cases transparent water should be drawn after opaque objects but before transparent objects.

Shader Transparency not working, any help?

Skyboxes are drawn in between all opaque and all transparent objects. RenderType tag categorizes shaders into several predefined groups, e. DisableBatching tag can be used to incidate that. This is mostly useful when you are using shader replacement on transparent objects and you do not wont to inherit a shadow pass from another subshader. This is mostly useful on semitransparent objects, because there is no good way for Projectors to affect them.

It appears to be functioning as expected in the scene view, but the camera in the game view is completely wrong objects clipping in and out of existence, not rotating with the viewpoint, etc. The code for my shader is below, any help is much appreciated. Shader seems to work perfectly fine for me. Are you sure you have the shader assigned to the material for these objects that are misbehaving? In any case, maybe this fantastic billboard shader pack can be of some help? Not sure why that fixes it, but for now that's good enough for me.

Funnily enough, I downloaded that shader pack and ran into the exact same problem I'm having with my own, haha. Perhaps I'm expecting behavior different from what's intended with these.

On the left is what I have in the scene view, with all the prefabs pointing directly at the camera. The right is the in-game camera viewpoint, which I've managed to move as closely as possible to match the scene view camera. It looks like the objects aren't adjusting properly in relation to the in-game view space.

Is that how these shaders are supposed to work normally, or am I just running into some other weird issue? I have the same problem, did you find a solution? If I create more than one it disappears, and if I delete all copies - it appears again. But for Editor View all is working always. I had the same issue after upgrading to Universal Render Pipeline from inbuilt.

The problem shader uses lots of in-built variables and screen space calculations, maybe post-processing updates these or something.

Unity 5 introduced the Standard Shader which replaces this shader. Cutout shader is an alternative way of displaying transparent objects. Differences between Cutout and regular Transparent shaders are:. This shader uses an alpha channel contained in the Base Texture to determine the transparent areas. If the alpha contains a blend between transparent and opaque areas, you can manually determine the cutoff point for the which areas will be shown.

You change this cutoff by adjusting the Alpha Cutoff slider. Diffuse computes a simple Lambertian lighting model. The lighting on the surface decreases as the angle between it and the light decreases. The lighting depends only on this angle, and does not change as the camera A component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture.

Eevee treats transparent objects differently than Cycles. They are sorted from front-to-back per object and do not receive any screen space effects. This is fast and works fine for many cases, but it is only approximate and gives incorrect results for some object shapes. For more accurate results, enable Alpha Hashed transparency in the material. With a sufficient number of samples to resolve the noise, this gives accurate transparency. Sign up to join this community. The best answers are voted up and rise to the top.

The z-sorting of the cards is the exact opposite of what it's supposed to be. I know that transparency is the problem because the z-sorting works properly when it's disabled the pragma alpha:fade in the shader is removed :.

From 3, I'm guessing that if I can somehow force ZWrite On despite the alpha:fadeit should work as expected. But chances are there's something else I'm missing that could work. When you create a new material, under the hood its Custom Render Queue property defaults to -1, meaning "use whatever queue is specified in the shader file," as we would expect. But as soon as we change the material's shader to use a custom one I've now tried this with newly-created Surface and Unlit shadersUnity sets the Custom Render Queue tomeaning "ignore what the shader says and always render this in the opaque geometry queue".

That seems blatantly wrong, so I expect they'll fix that. In the meantime, as Toomai discovered in the comments above, we can fix this by Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

Why does this transparent shader cause objects' z-sorting to be backwards? Ask Question. Asked 3 years, 7 months ago. Active 3 years, 7 months ago.

Viewed 7k times. The problem is this: The z-sorting of the cards is the exact opposite of what it's supposed to be. I know that transparency is the problem because the z-sorting works properly when it's disabled the pragma alpha:fade in the shader is removed No effect. Changing the subshader's Queue to things like Transparent or AlphaTestor removing it entirely. Does nothing because the generated code forces ZWrite Off due to having pragma alpha:fade as far as I can telland putting the line after the pragma in hopes of re-overwriting it is a syntax error.

Other notes: The problem is very consistent: the back-most cards are always drawn front-most, no matter what the shuffle is or whether the lower cards are ahead or behind. There is no alternative to using full transparency; pips can be any colour against any background. The face card designs don't use transparency. All cards use the same material, which uses a single texture atlas. Toomai Toomai 2 2 silver badges 9 9 bronze badges.
