### Why an emission object behind a glass object lost its emission property

Because emission pass contains only emissive rays hitting camera directly. Glass (even transparent) is technically a surface blocking the ray and what you see in render is transmission. So for ...

### Make a projected image from the camera follow the object orthographically

This approach calculates the direction from the camera to the shading point, as if the object was at (0,0,Z) in Camera space, by subtracting the object's location in Camera space from the shading-...

### Shader Node Color Ramp POS gradient depending on axid?

That can be this way: Use the wave at some scale. Shift the gradient input coordinates so that it start a bit later and scale it so that shift + scale = 1 (when X is 1). Compare the two. Wave goes ...

### Grazing angle translucency bug artifacts?

What you are facing is most likely the terminator effect. It happens mostly when there is only 1 light source that hits some of the faces at a grazing angle: https://blender.community/c/...

### How to get perfect linear gradient?

First of all, the Generated texture coordinates will always be 0 to 1 on X, Y and Z no matter what size the object is (assuming the scale of an object is applied). This means, when you take those ...

### How to make circular transform texture coordinate?

I'm not sure what the swirl and repetition is, so I made some assumptions. Use the length from the center and map it to a new range. That is how you can control the inner and outer radius. The radial ...

### How does the multiply color node work?

Multiply simply multiplies red of one image by red of the other image, green of one image by green of other image and blue of one image by blue of the other image. Since color components are in range \$...
