• 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.

FSX SbuilderX - Blends-Mask

Hello,

I don´t get my blend-mask to work with SbuilderX. On the pic you can see where are my problems. I have a few red spots and I can still see the water from the image where should be the FSX default water (see the red line for example).

I already have succesfully used blendmasks with maps2.bgl. I don´t know why it doesn´t work correctly here. It must have something to do with my .tif generation, I guess. I made the .tif from original bmp. It has 8 bit. Is there also a need for special resolution or something else? I saw that autogenerated Map2.bgl .tif´s have a resolution of 4096x4096.

Any help is very appreciated!

Thank you!

The blendmask should be the same size in pixels as the original source.

The blendmask file size would normally be 1/3 the size of the source file, as it should contain 8 bits vs. 24 bits for the source.

It's just my way of working, but any blendmask I made/make gets run through IrfanView before use. Irfanview has a keystroke combo for changing to grayscale and then for saving. Some times, other editing programs get real close to what Resample needs, but IrfanView spitting out the file works all the time for me.

You should see the pink/red areas disappear if you remove the NullValue line from the INF file and manually compile the file, IIRC? :rolleyes:
 
Thank you for your help!

What exactly do I have to do when I open the blendmask with IrfanView? Is just saving enough?
 
Hmm,

removing the the NullValue line from the INF file solved the whole problem. pink/red areas are disappeared and now the water is correct shown.

What is the NullValue line for? In the INF files which maps2bgl generates there is also that NullValue line but I never had have such problems.
 
A NullValue tells the compiler to not process (include in the file) any area that matches the value given. NullValue=1,1,1 is pure white, if I remember correctly? Pure White is a valid color (isn't it?), so why disregard it? Then when coupled with a blendmask, it tends to introduce those nasty pink/red spots.

Sounds like you're back to working, rather than debugging! :D
