• 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.

Creating custom groung poly textures

I want to create my own custom ground textures from cgtextures. I've never done it before and wanted to get some advice. If I download a seamless texture of, say, an asphalt texture and load it into photoshop, do I need to do anything with it before saving as a 32-bit bmp file (and a separate 24 bit bmp file) to use in the ground poly editor? I realize any editing I want to do to the texture I do it in photoshop but does the texture need and alpha layer? If so, why and how black or grey does it need to be?

Todd, I don't know what are "cgtextures".

Basically what you are asking is "how long is a piece of string?". What you need to do in Photoshop depends on what you want to do with the texture. Alpha channels control transparency. Do you want the texture to be transparent?

I suggest you do what the rest of us have done. Experiment. If something works for you, great. If not, try something else. There's no problem you're likely to encounter that hasn't already been experienced by someone else and that hasn't been addressed, perhaps dozens of times, in these forums. If you reach a dead end, the forum has an excellent search capability.

My experience with cgtextures has shown that the texture resolution is always different due to how they source their stock. The most important thing you need to do in Photoshop is re-size the texture into a power of 2. For instance, you could use any combination of these numbers.. 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096.

Examples are: 16x16, 128x128, 512x512, 128x1024, 1024x1024, 1024x2048, 2048x2048, 4096x4096.

Hope that helps, any more questions just ask.
