• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Sky Textures

Hi all,

I'm creating a third party application for use with P3D that needs to be able to figure out the current sky colour. I have some questions about the sky texture format and the process/parameters that P3D uses internally to calculate the merged color value for a given sim time. I couldn't find any of this info in the SDK, but perhaps it's hidden somewhere I didn't look?

Given this screenshot (https://drive.google.com/file/d/0B012srY358MYQ2liWmg1cTFIZE0/view) of one of the dawn textures:

1. What are the single colored pixels used for in the top row of pixels? I *think* they are used by the rendering engine for calculating the colour of shadows/fog but more accurate/exhaustive details would be useful. Is there a nice annotated example texture somewhere that explains these?

2. What are the in-sim time cutoffs for each texture (afternoon, dawn, midnight, morning, noon, postdawn, postsunset, predawn, presunset, sunset)? I ask this since the time at which each version starts to blend in/out would be required in order to calculate the correct "blended" texture as P3D computes it.

Many thanks for any help you are able to give.

Best wishes,

Wills
 
Regarding your first question, Jim Robinson explains in this FlightSim.com post:

Jim Robinson said:
In reality though, there's a row of pixels across the top of each sky texture that shouldn't be filled, they control a number of lighting effects in the sim. You can darken your environment up for gray days by just changing the color of a single pixel on each sky texture, here's a diagram of which pixels control what:

Your second question differs depending on which day you select and where you are in the sim.
