I want to put a ship over a city but make it look really big and have that white hazy look to it, like the death star has here. See how it's transparent-ish and kind of smokey white? How do I do this in blender(cycles)?

I've been trying to tackle this challenge for a week or two now and I'm still somewhat stumped. I am trying to create the effect of a moon or large planet seen in orbit from the surface during daylight, when the darker values fade behind the blue sky and the brightest values shine through.     I'm trying to make this effect with RenderLayers compositing nodes, which I still don't really understand compared to shader nodes. I know the solution should involve mix nodes and color ramps, but I haven't  been able to get anything close yet. I've tried mixing the environment socket of the layers node with the image socket in various ways but I'm still stuck. Can someone point me on the right path?

I want to recreate the above images for an animation. How do I go about it? I tried using particle systems and smoke simulators but to no avail. Also, I want to model a sparkler, but more akin to a sparkling point or sphere that emits in all directions.

I have a picture of a room including the floor and I want it to look like there is, for example, a cube going through the floor. Is there a way to do this, maybe by making it go through a plane that is transparent to the photograph but not to the cube?  If anyone knows how to do this, as I'm not very good at doing things from text, would you be able to explain with pictures or something? Is there is a tutorial for this sort of thing?

How do I create this type of effect with an image? I'm wondering how to get the thick edges and the tilted look. Is there an online tool that will convert a flat image to look like this?

I'm currently trying to create an effect like the one displayed below in Unity:    However, it seems that I can't do this with any of Unity's built-in light objects, and I simply cannot find anything online that talks about this. Is there a way to achieve this in Unity? 2D or 3D solutions are fine, as I'm sure that they're both very similar to each other,

I have a problem. I'm working with an object at 50% opacity. When it's over the artboard itself the color looks great, but when I put a white object behind it I get this weird color that doesn't look accurate.  This happens with every object and only in CMYK. I'm pretty sure this never happened to me before so maybe I changed something in the settings or I don't know.  Does anyone have any idea?

Basically, I would like to make it so that the lighter a pixel is (the more white it has) the more transparent it becomes. Black pixels would be opaque, white pixels would be transparent.  I currently use the slider in blending options on the first tab to get rid of the white and make it transparent but find it works slightly better if I use the magic wand tool with delete.  I figure that there is some blending option out there but there are so many and I'm not sure which to use to achieve my goal.  (Using Photoshop CS6)

I am wondering how to recreate some kinds of effects (you can easily do in Photoshop) in Blender.  I want to create the gradient textures like ones pictured below, should I render objects and blur them in compositor? Or can I achieve it using only material nodes?

I would like to to create the image above. I have tried to make multiples layers of the waves and edit it's opacity but it does not seem to work. I would really appreciate some feedback and guidance. Thank you.

I'm kinda new to Blender. Currently playing around with version 2.8 to practice some rendering. Is there a way to achieve this 'light-star' effect for the blooming objects with the emission? If there is an alternative way then it's fine too. See these images below for references. Thanks in advance:

I was watching the  tutorial by Andrew Price and I was able to follow along in Cycles until I hit the part where he mixes the day and night materials together so that the lights show up on the "dark side" of the earth.  How can I recreate this effect in cycles? I thought I could use the ray information to tell me if there was incoming light but I've found no such node to give me this information.

I'm following  and I've set my compositor up in the exact same way as he did, except my background is like a slightly light grey and I don't know why.  In his video's he's getting a bright white as his background and I can't see where I'm going wrong.  Here's the render:   Here's the compositor window:    file.  Please help! I really want to know why it's not happening.

I used the Import Images as Planes addon to import an image. It works fine but how do I change the transparency? I want to animate the plane so that it fades in and out. Here is my current node setup:

I would like to use the overlay effect used on the screenshot(s) below.    I've tried experimenting with several Blending modes but keep missing the mark. I'm sure this has a very easy answer but I'm having trouble recreating the effect on my own.  Here are a few more images for further context:        Thanks in advance for your help.

I want to make object transparent, but the object itself should not be visible through itself. It's in an animation that rotates it, but at a certain angle I can see parts of the object through other parts of the object, which I don't want. So object should be transparent for everything in the scene, but this object. Below I pointed with red arrows those "whiter" pieces that are semitransparent white over semitransparent white which I don't want to get:    Currently it have 3 materials on it (front, back and sides) and transparency + backface culling is done like this:     For rendering I'm using Cycles engine and Blender 2.73.1. Is there anything I could do to make that happen? I think it got something to do with geometry settings but I have no idea what to set and how.

Given have two shapes for example. a star (blue) and arrow (no fill). The arrow has a green stroke.   How can I make the portion of the star which is behind the arrow transparent, but retain the green stroke on the arrow?
