Surf effect difference in v3 and v4 - same file

Postby kevinfirth » Sun Jun 11, 2017 7:00 pm

See videos showing the same wave effect in both p3d3 and p3d4...

v3

v4

Is anyone else see their surf effects vertical? You can see in the videos that in v3 its normal, just weird in v4...

This is Earth Simulation Scilly Isles. The scenery contains not custom effects for waves/surf, so I'm assuming the effects seen here are default.

Thanks K

Ive tried flipping the texture files fx_swoosh anf fx_swoosh2
Heres another video after that.

You can clearly see that the surf texture effect is vertical out of the water instead of horizontal on top of it.

Makes me think off an effect I am using. My paratroopers jump upside down. I know in my case it has to do with the fact that BMP-files are not supported any more. May you have a similar problem.

You can use .bmp files... HOWEVER.... you must flip them vertically and then save them as .DDS. You can do this using DXTBmp, freeware.

Hi folks,

There are a number of issues here:

In P3D v3, in order to deal with the problem of applying an effect to the surface of 3D waves, in addition to the flag Ground Normal =1, the flag ‘Ground Decal=1’ must be added to the [Particle.n] section of the effect.

In P3D v4, this is required whether or not you use the Ultra setting. The current Orbx libraries fix this issue for Orbx specific effects. I would expect other developers to likewise address this issue. If you can’t wait, you could do it yourself if you have some familiarity with effects and do it carefully. Specifically, don’t add Ground Decal=1 if the flag Ground Normal is set to zero.

In the initial release of v4, textures for effects are flipped upside down. I think it is safe to say that this will be fixed soon. It might be worth waiting before you edit textures. In addtition it turns out that there as been a long standing error where effect textures were fiipped left right. Again I think I can safely say that this will be fixed.

My suggestion; wait a bit. :-) 

NM, I've narrowed this down to an add-on effect.
Default effects in default scenery work fine.

My add-on scenery I'm seeing this with does not add the effect in question so I've tested with various add-ons activated to identify the offending package. It is another Earth Sims scenery - their 6.1 Scotland autogenesis.

It's fixed by adding the Ground Decal=1 to the particle section...
