"Ghost" object : A bug ?

[kiwimage]

Hello Aoktar,
I think I have a bug on this scene. I'm not sure what's going on.
I have 2 different objects (a house and a cart)in this scene that appear semi-transparent in the renderer, for no reason. see the house in the center of this image.

The material is the same as the other houses.
The mesh normals are pointing in the correct directions.

Funny fact : instances of this object render correctly.
But for the other object, the cart, instances inherit the weird transparency.

sounds like that you have objecttag with opacity

No I don't have any object tag on this objects, just a material tag.

I am trying things, I 'll let you know.

Hi again,

I've been testing different options.

- adding a c4doctane object tag seams to fix the trouble.
- instancing the object fixes the problem
- simple duplicating doesn't solve anything.

precision : it occurs with any material (i've tried to switch materials, it doesn't come from here.)

Salut Kiwi,

Si ce n'est pas les matériaux, c'est probablement la géométrie et je ne vois guère que l'orientation des normales ou peut-être le ray epsilon ou un problème d'échelle...

Désolé de ne pas pouvoir t'aider d'avantage.

Tu devrait peut-être transmettre une scène réduite comportant le bug pour qu'il puisse voir de quoi il retourne.

it's possible a bug about on apply a material to selection and hierarchy. I need to check this part

Thanks for looking into it.

It may also have something to do with the objects order in the hierarchy, I have noticed that the 4 top objects in my null have the error,
if i create a default cube and i place it first in the hierarchy of the null, it solves the problem for my 4th object (that becomes 5th).

If you want the scene to reproduce the error, i can send it to you.
I have also made a video capture for you, that I'll upload tomorrow on the web. (right now I need some bandwidth).

scene will be much better to test it, maybe a bug which is overlooked.
thanks

I just sent you the files in PM.

ok, this is a stupid bug. Display tag is accounted for visibility but it's not checked. Also it's affecting the below objects due a bug.
I'll fix it
