object lights

#61

nope. that thing is controlled internally by mentalray.
I think it puts a light on each point vertex of the mesh.

after adding the parti volume and getting some volume light effects I found that you can edit that falloff further by changing the ‘start’ value that sits beneath the exponent in the geocolour options.
by default its at 0 and the end is at 100.

lightobject is set to physical as always but If I change the values beneath so the start is at about 30 or 40 I start getting a more spotlight like effect from the objects shape.

I still need to play about with it more but I had real difficulty getting fog with the parti volume - I find that I have to turn that scattering colour value up to get pronounced fog effects in the light but then that also bleaches the rest of the scene with fog.

might have to lose the lightfog in my scene - I only want to do a seperate pass and comp it in afterward but its really faffing with my head :confused:

Is anybody using these shaders with Maya 7?

I’m getting error messages stating both crtl_geolight and crtl_objectlights as undeclared functions.

#64

Me too, in Maya 7 I can not connect any of the geometry shaders to a transform node.
My errors are:

connectAttr -force mib_geo_cylinder1.message |locator1.message;
// Error: The attribute ‘locator1.message’ cannot be connected to ‘mib_geo_cylinder1.message’. //
“connectWindowWith mib_geo_cylinder1.message locator1.message”;
// Error: “connectWindowWith mib_geo_cylinder1.message locator1.message”; //
// Error: Syntax error //

I got it, seems the Maya scripts werent updated to the .miGeoShader attribute…

#65

I don’t know on my maya7 any geoshader attached via the CreateRenderNode
seems to return an error in the script editor. I think it is a maya bug as this
does not happen in any previous versions. all I do is to drag the geoshader from
the hypershade to the mr geo field in the transform panel of the obj I’m going
to use for that, or simply hardtype its name in the input field; in this manner
works quite good. if you found other way to fix this let me know.

Is is nothing big but definitly a bug. They introduced the .miGeoShader attribute and forgot to update the Template scripts. If one connects by hand everything works fine. The jpmakeObjectlight.mel script does it correctly by the way. It would be probably a good idea to include this script with the shader release, saves a lot of hassle…

#67

Great francesca(the queen of)luce!!! This shader should work great for neon lights or similiar.

#68

Hi everybody and thanks a lot francesca for Ctrl_objectlight and Geocolor :slight_smile: and also Nojjy for the useful script.

I would like to know where i could set the quality of the shadows emitting by the objectlight?
I search in the geocolor attributes but i can’t find …There 're just the “Enable”, the Umbracolor and the TraceDepth…

Here is a test render…

Thanks in advance for your help :slight_smile:
Bye
ps: Excuse my poor english…hihi

I can’t find the attribute for this…

select the light

under lightshape, open the mental ray area light properties and increase the sampling values. they’re usually at about 2 & 3 …set em to something like 3 and 6

#71

Has ctrl_geocolor ever been compiled for linux? I see the linux version of ctrl_objectlights but not ctrl_geocolor.

#72

Is there any other way to control which normal of an object is lit other than ctrl_geocolor? As of right now there’s no linux version of that and so it’s off limits to me.

#73

wait a bit man, I’m adding vertex color support.
one will just paint in viewport his objs and they
will return that colors as geo lights. obvioiusly
I’m finding some problems doing that… cannot
find the ‘address’ where cpv reside… any dev
that already found where they are in maya7 ?

#74

is this beauty compiled for osx too ???

#75

Had some problems with the file, first it was saved as attachment.php, after renaming it in ctrl_geolight.zip it was fine. But the content somehow irritated me, it was only for Maya, there were no spdl’s. Does anybody has the working files for xsi 5.x ?

Most gracefully

#76

the content irritated you ? This is the maya rendering forum.

#77

oopsala :smiley: did a search for Ctrl_Objectlight and it didn’t even come into my mind that Maya doesn’t have that integrated. Oh well, nothing happened, back to work, hehe…:beer:

Frohe Weihnachten
