• 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 Prepar3D v5 effects photoscenery issue...

I have dynamic lights working in V4 with out a hitch, but in v5 they show on the photoscenery 1000x brighter than in v4. They still display properly on the ground polygons however.

Any suggestions?

This turned out to be an issue with the intensity and scaling of the effect. In v4 a high intensity is ok, not in v5.

Hi Shaun.

The glaring light could be that the developers of the P3Dv5 have made changes to the particle system. In my projects, all P3Dv4 Effects files for the P3Dv5 have to be revised. There are 2 new values in the "ParticleAttributes" section:

[ParticleAttributes.0]
Color Start=0, 0, 0, 0
Color End=255, 196, 136, 1
Bounce=0.00
X Scale Goal=0.00
Y Scale Goal=0.00
Z Scale Goal=0.00
Falloff Exponent=1.0
Inner Cone Angle=45.00
Outer Cone Angle=180.00
Intensity Day=0.00
Intensity Night=100.00


In addition, the effect is now switched on or off via the "Color End" value: 0 = OFF, 1 = On

So much for my discoveries regarding the changed particle system. Hopefully it will help you a little :)

Hi Christian, I need some guidance...I followed your details regarding "ParticleAttributes" and tried it on a dynamic lighting effect that I created with MCX. I modified the effect file (since MCX does not include the items you stated above in RED) but running the latest P3Dv5 hotfix 1 and SDK, the effect "Intensity" remains as the last number in the Color End statement. Setting that to a 1 as you mentioned, reduces the "intensity" to 1 (aka, near zero), the Intensity Day and Intensity Night have no effect.
What in the world have I done wrong..or misread?

I don't know if you did something wrong or if you read something wrong. The post above from me relates to the light type Spotlight (type 28). Do you use this type of light or do you use a different type of light?After all, it may also be possible that with Hotfix 1 this problem described by Shaun no longer occurs.
