Emmiters in vehicle!

[Gilmer]

Why after update to 2.4 version, dont's emitting particles in vehicle? For sample, in 'vehicle_viperscout.lua', if i put:

object.emitter[n]:Paint(LoadMaterial("abstract::roaddust.mat"))

It dont show the particles, in previous versions showed:

Now, if i change to:

object.emitter[n]:Paint(LoadMaterial("abstract::dust.mat"))

It show, but dont get the terrain color.

The materiais is:

roaddust.mat:

texture0="abstract::smoke.dds"
depthmask=0
blend=alpha
zsort=1

shader="abstract::particles.vert","abstract::particles.frag"

 

 

dust.mat:

texture0="abstract::smoke.dds"
depthmask=0
blend=alpha
zsort=1

shader="abstract::particles.vert","abstract::particles_roaddust.frag"

someone could be try, to see if occurs the same problem, please...

[Richard Simpson]

I'm not sure where to put this code you have written. But I don't get any emitter on the viperscout either. Even though there is a big section of code in the vehicle_viperscout.lua about emitters.

[Gilmer]

So Richard, thanks for the help. The line that i commented, are in line 92 in the "vehicle_viperscout.lua". And the materials, are in "Materials\Effects\Particles"..

 

This is strange, because in previous versions, are working normally...

[Gilmer]

nobody? I'm really needing this..

[AggrorJorn]

I am not getting any particles at all in 2.4 for this vehicle. Something did change in the particle shader because particles do not receive a random draw angle when being created. Whether this has something to do with these particles, I doubt it.

 

have you tried copying the old script to the new one? perhaps there is a small change. I don't see any other reason why this isn't working.

[Gilmer]

Thanks for the answer Aggror. I did not copy the old script. I deleted and did update to see if occurs with the new script, and the result is the same.

 

The script of viperscout.lua is this, i dont know because not's working..

 

require("scripts/class")
require("scripts/loop")
require("scripts/math/math")

local class=CreateClass(...)

function class:CreateObject(model)
local object=self.super:CreateObject(model)	

function object:UpdateMatrix()
	self:UpdateTires()
end

function object:UpdateTires()
	local speed
	for n=0,3 do
		if self.tire[n]~=nil then
			self.tire[n]:SetMatrix( self.vehicle:GetTireMatrix(n) )
			if self.emitter[n]~=nil then
				self.emitter[n]:SetMatrix(self.vehicle:GetTireMatrix(n))
				self.emitter[n]:Pause()
				if self.vehicle:TireIsAirborne(n)==0 then
					speed = math.abs(self.model:GetVelocity(0).z)
					speed = (speed - 4) / 20.0
					speed = Clamp( speed, 0, 1 ) * 0.1
					if speed>0 then
						self.emitter[n]:Resume()
						self.emitter[n]:SetColorf(1,1,1,speed)
					end
				end
			end
		end
	end
end
