Hello there, at some point in time, one of the leopard releases, made MANY .dmg files seem to be “unusable” to open, but all you need to do, *i hope in your case really*, is instead of “double clicking” the .dmg, you should just RIGHT CLICK THE .dmg, then go to “more” and “mount it”…
Hope that works for you!
Jonathan
Thanks for all the replies. I downloaded again, this time using Safari. I don't know if it was that or something else but it's working now on the 430 release. Yay!
Cheers

Hi, I should have said
OSX 10.5.8 Leopard so yes, 64bit I have had apprentice running on this machine before but I uninstalled it but now I can't open any of the DMGs that I have downloaded from sideFX

Hi,
I've just been trying to get Houdini installed again on my macbook but I have tried downloading
10.0.401, 430 and 450
they all give me a “the following disk failed to mount - not recognized” error. I find it hard to believe that there's anything wrong with the DMG from sideFX because someone would have mentioned it by now, so is there some magic I need to get it to work…?
cheers

Awsome Georg, thanks!
I was getting there slowly though I think I'll have to take a look at lsystems to get the final result I'm after.. now back to shading *yawn*

Thanks for the reply
as far as i know with a ray sop, you ray points from an existing mesh or pcloud to a surface. It's not quite what I need to do.
In 90% of cases it;s going to be an imported obj so I don't think this would work but I might try to convert the geometry.
I'm pretty sure there will be a way to get a position on a surface (maybe via vop sop?) and then add a point to that position. I just son't know how to get that position info yet
Thanks
john
You can use a Ray SOP. Make sure you have normals on the points aiming towards the surface.

Alternatively, you can use a Creep SOP if the surface is nurbs or mesh.

Hi,
I have a simple question. How do I add a point onto a surface? I know I can flatten the mesh based on the uvs and add the points in 2 dimensions then transfer them back up to the 3d space but… I don't want to I'd like to create a set of points on a surface like the scatter sop but in a non-random fashion.
any help is appreciated,
John

what happened to houdini 8s render_envmap parameter…
or how do I render an environment map of my errr.. environment in houdini 9.1?

Technical Discussion » delayed load and material override

If you only have on material on the geometry, then you can simply assign the material at the object level, and it will be used.
And if I'm not applying the material at object level?
When I have time I'll try to get a concise example of the problem I'm having. It may well be user error
Basically I can only get shaders to render on a delayed load object if the shader parameters are baked in with it. In a shop node case it would be a vm_surface attribute, therefore I if I change a shader parameter I need to render out a new geo file, and if there are shot specific shader tweaks then I'll need to render out shot specific geos. I'm not sure how a material node works with shader parameters yet but I've not been using them for long.J

ok that seems fair enough, thanks.
deviating slightly here but is there any way to render geometry from file but to keep the shader attributes separate and to only have link to a shader. Or, to put it simpler, does the shader information always have to be baked into the geometry when using delayed load geometry?

Hi.
is there any reason why using Local Override on the material node breaks when rendering delayed load geometry?

Hi,
I'm trying to edit the string below:
op
obj/defaultShaders/wireOccMaterial/occWireframe input2 1 angle 0 samples 4 parm 0 scope “*”
to
opobj/defaultShaders/wireOccMaterial/occWireframe
ie. deleting everything after the first space. I need to do this on all surfaces assigned to a model and not just this one so a simple replace isn't what I'm looking for. Basicaly I need some way of deleting everything after the first space.
any ideas?
John

Hello again.
I've looked at the Shader Unwrap stuff on the odwiki and some posts here but I'm not able to get a proper bake of a surface. It seems the baked render depends on the camera position or something.
Perhaps I'm taking a too simplisitic overview of the process but I would have thought the camera would have nothing to do with texture baking.
Anyway, attached is a file that should illustrate my problem.
Cheers

Yeah.. it was a little shot in the dark but as I'm not able to update the houdini module for our farm software I can't do much about it myself. I'll pass on your info to the correct autorities
Thanks again.

Hello again
Is there a way to specify frame increment in Mantra command line? I'm looking ant the Mantra command line options in help but there's nothing on it. The reason I ask is because our farm software doesn't seem to do it, yet.

Hello Sy,
unique channel names is fine if there is only one output image file and makes total sense. The thing is that we are outputting image planes to seperate exr files and we would like the data to be in the rgb channels.
And of course, true to form, I have found the soulution while writing this email It appears I need to add “C” in the channel name to get the VEX variable data into the rgb channel of the respective exr…. hmm obvious really.
Thanks

Hi,
When I specify a new image plane, lets call it “AOVrefl”, and render out an image the channels are named:
AOVrefl.r
AOVrefl.g
AOVrefl.b
even though the channel name entry is empty. This makes it highly annoying to work with in Fusion as we have to select the correct channels for each loader as Fusion is expecting the channels to be called r g b with no prefix.
Is there any way to not get the image plane name appended channel name?
