attached object editor : rotation problem

[pierrot1951]

Hello
I create a waterfall object to make more realistic scenery. For testing version I use a solid part to make placement easy in very slopy areas + fx_WaterFall.fx effect.
In definitive version, when placed in good place, testing object will be replaced by a model without the big solid part (just a small transparent triangle at origine).
I try to make water going away from cliff by using different inclinations : setting 0 deg (vertical fall), 10 deg, 30 deg in the first rotation parameter of MCX adding effect editor.
In MCX, it works ok, with the different fall inclinations.
But in FSX, it seems that rotation parameter doesn't work : the 3 rainfall are all vertical.
Screens: MCX with correct 3 inclinations 0, 10, 30 / Setting of parameters for 30deg / FSX result
Thanks for help; Pierre

Rotations are broken in FSX. It’s a bug that was never fixed.

IIRC, one may be able to control orientation of an attached waterfall Fx via its "Pitch" parameter value (not sure Hierarchy Editor can edit this).:

I would use the live in-sim preview by activating visualfxtool.dll in your P3Dv4 DLL.XML file.

I'm not sure Arno's FxEditor shows a waterfall preview with an Fx extrude direction along an assigned planar axis.

http://www.prepar3d.com/SDKv3/LearningCenter/modeling/creating_special_effects.html

Orientation p, b, h

The initial orientation of the emitter, given as degrees, from the axes of pitch, bank and heading.

Pitch=0.00, 0.00 Bank=0.00, 0.00 Heading=0.00, 0.00

Also, There are generic waterfall Fx and (1) that falls with auto-extrusion along its complete planar axis until it 'Bounces' off ground level.

I would need to test this live in FSX, but IIRC. fx_WaterFall.fx is that latter (1) due to use of "Bounce" in its Effect Parameters.

If so, IIUC, it is forced to fall vertically to the ground below, although it extrudes slowly to display over the entire planar axis.

Bounce=0.00

The reaction of a particle when it collides with the ground. The larger the number, the greater the bounce. If the parameter is set to 0, no reaction occurs. If it is set to 1.0 then it will come off the ground at the same velocity that it hit it. Use a value less than 1.0 to simulate the loss of energy due to the impact.

fx_animaldust.fx( Bounce=0.00 ) fx_BilgePump.fx( Bounce=0.20 ) fx_CampFire.fx( Bounce=1.00 ) fx_WaterFall.fx( Bounce=0.00)

Thus, a generic waterfall Fx with with a (lesser) assigned extrusion along its planar axis may not necessarily display over the 'entire' planar axis

That may be possible. I was only talking about the placement of the object. So that could be a solution.

I am "inclined" to display agreement with that as IIRC, one can place the Fx and control its planar orientation more easily via XML.

I'll try to find / post an example waterfall placed as a BGLComp XML-coded BGL using planar orientation ...that is NOT attached to a 3D model.

I know I have one somewhere; all I have to do now is find it.

Hello; great thanks for detailed answers. In similar idea, I had allready noticed that banking, pitch parameters in Instant Scenery have no effect in FSX. I'll take time tu read carefully.
