• 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.

Blender 2.79b (uvMapping Issue)

I'm getting completely inconsistent results in my uvMapping, feels very buggy.
I've watched 4-5 tutorials on it, I know about setting the UV mapping nodes in Cycle Render mode.

1) I create a new UV Map file from the UV Editor
2) I select SmartUV project
3) It creates the UV boxes properly

I am able to render, but it usually only works the first time.
After that, things become completely messy (missing or black textures, random bake results - distorted textures)

I've tried Fixing Normals, setting scale and rotation, creating a new UV Map file each time.
I'm also creating a separate sub-map for each material and texture.

Nothing seems to work correctly except the FIRST time I run the baking, then it usually works except a couple textures are in the wrong rotation.
Well, I fix the rotation of those textures, then they render blank. Also the Smart UV project starts suddenly only taking half the space, and I have to uncheck FIX ASPECT.

I really do not understand why the baking would vary on each run without myself even making any real changes to the model.
That seems like a bug?

Hello...

It might be best to see what you are referring to as buggy. Some pictures might help with your attempts (step by step that is).

SOME TIPS / QUESTIONS
0. Some (crystal clear) screenshots would be very helpful for others here to see and understand what is going wrong at your computer.

1. Which "tutorials" have you been watching, where and made by whom ? since there is a huge varity in blender tutorial quality in the field?
2. What exactly are you rendering and how, under which Blender Internal? Cycles? EEVEE? settings (see 0)?
3. What do you mean by rendering "blank" -> the purple missing-texture-color of black / white / option 3,4?

4. Have you already posted your question on the following other Blender community platforms?
- https://blenderartists.org
- https://blender.stackexchange.com
- https://www.twitter.com under the #Blender #Blender3D and/or #B3D hashtags?
