• 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.

P3D v4 HDR Lighting setting and Destination Blend/Source Blend (One/One) Material Settings.

The common method used for creating nice glowing light halos is to use the One/One material setting with Destination/Source Blend on a textured plane with a black background in FSX. This also works nicely in P3D, except, - I have now discovered - when HDR lighting is enabled. The result is no longer a soft glow which blends nicely with everything behind it (except clouds) but a much harder-edged, brighter halo.
HDR OFF (soft glow)

HDR ON (hard, bright glow)

I originally thought this was just a shader change between FSX and P3D3+ so I set about using other material settings to get a softer glow. One/DestColor worked well initially.
HDR ON (one/one for lamp lights, one/destcolor for taxi lights)

Unil one day I happened to turn off my HDR lighting and discovered that my adjusted taxilight halos were now extremely dim to the point of being invisible. I tried turning my HDR back on, but they remained dim. I assume a shader must have been altered somewhere on my system.

Has anybody encountered this issue?
How have you built your halos and accounted for users who may or may not use HDR?
Have you just continued to use the one/one setting even if it may not look as pleasing?

Looking for feedback/suggestions/solutions.

Regards,
Zev.
