• 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.

Same Model, Different Textures. One builds, the second CTDs

Here is an odd one.

I am using the old ALPHASIM / Virtavia Lockheed C-141B, imported through MCX, to create a static model. BTW these were made available as freeware with the proviso of non-commercial use; my scenery is freeware only so I am ok with sharing.

I have two liveries: the old MAC scheme and the later EURO-1 green/green/grey. I am using the original textures converted to .png from .bmp.

One model, the EURO-1 scheme, builds in SDK and appears in the scenery. The second, the MAC Scheme, causes the build to CTD. I have ensured that I do not have duplicate GUIDs - see screenshot.

The blender model is the same just with different textures for the relevant materials. I do not have duplicates of common textures which are shared by both liveries.

The three output files from Blender are identical sizes - see screen shot.

I have not previously had this issue with multiple liveries of the same base model.

The linked .rar file has the Blender file; the three output files and the textures.


Any help gratefully received

Resolved - but I do not know how or why.

This morning I had another go atachieving the re-paint. I copied the working (EURO-1) model in Blender and started a second instance of Blender into which I pasted the copied model. I saved the model with a separate blender file-name and quickly edited the materials properties to draw on the MAC scheme textures. The model exported from Blender and interestingly had different file sizes from model which CTD'd.

It built and exported, then displayed in MSFS 2020 with no dramas.
