hi everyone!

i've got a rendering issue, you can see my problem in the “testrender.jpg” image, that i attached to this post (there's also a hipfile) - There is this white dotted line in between the gray areas and it shouldn't be there!

I've checked my VOP Network of the shader a thousand times, all my nodes are placed correctly, it must be some kind of bug.

it's not a problem of my mantra sampling, i already increased the pixel samples and the problem's still there.

Also i updated to the latest Houdini Apprentice Version, doesn't cut out the mistake.

My system:

Windows XP 64bit,
Houdini Apprentice 10.0.430
Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz
8190 MB RAM
DirectX Version 9.0c (4.09.0000.0904)
NVIDIA Geforce GT (GS) 1024MB
(Driver Version: 6.14.11.9062 , driver date: 17.08.2009)

Now it would be great if somebody could help me, i already reported a bug but i need to get rid of this immediately
:?

best regards,

Manuel

i just updated now my graphics card driver to the latest version,
problem's still there …

NVIDIA GeForce 8800 GT, driver date: 27.09.2009, version: 6.14.11.9107

:cry:

If you use mantra, the graphics driver should not have any influence over the rendering result. As far as I know, mantra does not utilize the graphics card to speed up rendering.

As far as my understanding goes, i believe something goes wrong with the calculation process inside my VOP Network of the applied material.

I only updated the graphics card driver to eliminate possible errors …
