• 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.

MSFS20 Problem with emissive texture

Hello everyone

I have made this building in Blender:
G7 Day.PNG


And now I am playing around with the lighting of the model at night. I have made an emissive texture for the obstruction light on the left. I have also made spotlights for the lamps and an emissive texture for the lightbulbs. This is how it looks:
G7 Night.PNG


But now I run into a problem. When I zoom away from the building the emissive texture starts to bleed out into the rest of the texture and make everything else emissive as well. It looks like this:
G7 Night2.PNG


Is there a workaround for this or do I have to have emissive objects on separate textures to all else?

Thanks for reading :)

Best regards
Henrik

They don't have to, but considering how "prominent" they are in the night, make sure they have enough room around on the uv to account for any mipmapping made automatically by the sim
 
Hello @mamu

Thank you for your input!

I have tried to minimize the band around the emissive UVs and have gone from this:
Trim2_EMIS.png


To this:
Trim2_EMIS.png


But it has made no difference. The emissive parts are still bleeding onto the rest of the UVs on the texture. Only a little up close, but further out it covers all the UVs. Could it be because I am using colours on the emissive texture? Should they be white?
This problem really baffles me.

This is my UV layout for the texture:

I hope the problem can be solved, otherwise I see no other solution, but to make the emissive UV have their own texture.

Best regards

Hello @Heermeyer

I have not made LODS yet, but I will be doing it, when I have solved this problem.

So your suggestion is to remove the current emissive texture and instead make simple materials for the bulbs in the lamps and obstruction light?

I will have to make it 2 separate textures because they are different colours. Is adding two more materials not a problem in regards to making to many draw calls?

Best regards
Henrik
 
Yeah, i think its better to have a couple of drawcalls than one emissive texture. And for these plain colors textures are not needed, just material with emissive settings.
