particles don´t render opacitymap

[JANGLED_NERVES]

Hy there,

I am trying to render a dandelion.
The flying thing is a Poly-object with three ID´s with the "head" as 6 planes via opacity (see first 2 images). So far so good.
If I render one of the object, no problem (pic 1). If I make a particleSystem out of it, via shape instance, the "head" is just NOT rendering (pic 3 and 4).

I am using MAX9 and vray 1.5.

Does anybody have a clou what the problem is? I tried to make meshObjects via "Mesher" out of the particleSystem, no success. I raised the max tranps. Levels und the secondary ray bias...also not working.

I´d really much appreciate your help, deadline is coming soon and I don´t know what to do...

greetings, d.

what particle system are you suing? pflow?

Its possible your using teh wrong material type.. static..etc.. or something.

There is a script which is what you might have used to convert the particles into normal mesh in which case it should just render like a normal opacity mapped object.

Im think it may be something odd with your material or particle setup.
If you can shed some light on those that would help...
are you able to share the scene? (looks pretty cool )

[JANGLED_NERVES]

Yes,

I am using PFlow. Wrong material, possible, but what is the wrong material, what do you mean?

Do you know the name of the script, you mentioned?

If you think you can possibly find out what the problem is, I would share the scene, no problem, but I would like to send it by email to you...if this is possible, give me your email adress (PM?).

greetings form germany...d.

I think this is the script. Easy and fast to use.

This is the one I was thinking of.

Try that and see how you go.
If you want to send it to me, press the email button under my posts.

Mesher works fine in max9. You just need to assign the pflow as your object. It will then snapshot a new mesh where you placed your mesher object, so you need to reposition it.

Ok, its got something to do with the map channels.

It seems to not be seeing your 2nd channel. If you set the opacity texture to use channel 1 it works but doesnt look right.

Im trying to work out why its stuffing up the map channels. I think it may be a drawback of the standard pflow.

[DaForce]

mmm i think your mapping may be odd.

As rendering it mesh doesnt look as good as rendering with the opacity and diffuse maps switched to map channel 1.

I would suggest you just do that.

Also turn the bitmap blue to 0.01 and turn of filtering as well for the diffuse and opacity slots. It will render a hell of a lot quicker and look nicer

[JANGLED_NERVES]

Ok,

what you possibly don´t know is, that I sent the scene to DaForce by email so that he could take a closer look on things.

AND HE IS RIGHT!!! Vray has a problem with the map channel if it´s not 1 (for the opacity slot). I changed that and now it´s rendering correctly. Thanks mate, you saved me!

Without the filtering it renders faster, but we have to do some closeups, therefore we need filtering.

And the last question I have is: what is "Bitmap blue to 0.01" ?

many many thanks for your help!!!

[DaForce]

Good stuff

Well no filtering is fine for close ups, you just need to boost your AA a little.
Yeah I meant bitmap blur its just above the filtering, try lowering that, as that will also help speed up renders.

Good to see its all work nicely.

[JANGLED_NERVES]

right, bitmap blur, I thought so.

thank you very much, cheers mate

[DaForce]

Not a problem mate
