Hey Folks,

Have some geometry that used cookies, facets and and poly operations.
Not very complex stuff but never the less there is a bit of work on the geometry. I made it in H8.1. I wanted to use of the new features in 9 so I decided to bring it into 9.

When I bring this geometry into H9, I get some problems, with rendering,
like some geometry has no shadows etc. I Pretty much have everything set as usual and it renders fine in H8.1.

So I figure it is a stability problem and decide to bring it into H9.1 and WOW, the geometry is messed up even more, holes,missing parts etc.

So I figure it is some sort of Open GL problem with my card and H9.1, so I set HOUDINI_OGL_ENABLE_SHADERS = 0 in my environment variables, as Houdini requested on start up, and still have the same problems.
Although the dialog that requests the ENV is gone now.

Any body know what the heck is going on, or is having similar geometry/shading issues when bringing stuff into H9 and up?

I get this on my Windows 32 platform, as well as my Linux 64 bit platform.
Running NVidea Quadro 580 XGL on Windows and NVidea Quadro FX 1500 on my Fedora Core 6 Box.

Tanks in advance,

Okay, so I merged the 8.1.866 file with 9.0.747 and that is what did it,
messed up the file somehow.

The merged file looks okay in 9.0.747 but has problems rendering.
When I bring that file back into 8.1 I get gobbly guke kaka looking.
If take that file into 9.1.124 I get goobly guke kaka looking again.

So I think there might be a problem translating the geometry in the
merge.

I am going to try to translate everything in 9.0.747 manually, that is
take out all the old sops, shops etc. and see if that helps to render correctly.

Any comments are welcome.

So looks I am back to 8.1 and not merging into 9 ^.

I take it you want to bring in the node network and not just the geometry?
What happens if you just open the 8.1 hip file in H9?
Any chance you can provide an example that we can look at?

can you open instances of both 8.x and 9.1, select the relevant nodes in 8.x, do CTRL-C to copy them then paste into 9.1 with CTRL-V?

just another option

Hi Guys,

Apologies for not getting back.
I eventually got everything into 9.0 but I had to delete older H8
geos and lights and remake them in 9.0, and render from a new mantra node also, some incompatibility I guess.

I could not however go to 9.1 as I get some pretty awful geometry,
when opening up in, cutting or pasting, etc, merging into 9.1.
Yes I can give you a simplified file if you need or can't replicate.
