Re: Architectural shader anisotropic trouble

Bumping the subject,

Because I found an "old" but cool tut by Luc Frolicher.
http://lulu1315.wordpress.com/2007/10/23/anisotropicfun-part1/

It's in 2 parts, worth the read if you're into anisotropy.

I have tried getting Anisotropic reflections using the Architectural

tried all sorts of combinations of UVs, tangent maps and texturemaps to

metal surfaces. What gives - is it broken or badly documented - or perhaps
I am overlooking something really simple here...?

Re: ICE: Basic Turbulence question

[Alan Fregtman]

You could multiply your desired turbulence by another, ranging from 0 to 1
of course... therefore where it is 0, it would multiply by 0, thus making
those areas "still".

Re: ICE: Basic Turbulence question

Hi,


Assuming 2012, you could turbulize the mesh using the"Turbulize Mesh" or 
"Turbulize Around Value" compoundsand then plug a Weightmap into Animation 
Speed.

I need to generate a basic turbulence across my cloud in order to drive some 
other values. The attached tree is what I am starting with but it's not really 
generating what I need. I am trying to create a clamp on the velocity of the 
cloud to create areas of stillness.  

RE: ICE strand orientation trouble - again :/ now with images

I would head in Rob's first suggestion - get the data from the emit location in 
terms of normal etc... and use that to set orientation of the strands.

Hi Byron,


I´d like to suggest you take the time to clean up the object in Maya.

The advantage is that your Normalpass will output useful information,
all shaders computing refraction or transparency, subsurface scattering
and last but not least reflection will give reliable output...

I know, it´s a pita but shading&lighting&comp will be far less error prone.

Personally, I´d look into converting to polygons and merging to useful 
shells.

Rhino, MOI, Maya´s convert to polygons.

The reason why I suggest to do the clean up/conversion in Maya is that it
gives you more options to edit Normals. Just make sure that User Normals
and Geometry Normals point into the same direction...

Once the geometry is in XSI, nuke the user normals and live with the 30-35° 
smoothing...


Cheers,

Sandy, just so you know because it isnt that obvious, it was me that wrote that 
tutorial :)  also Arda, I imagine the orientation problem you are having is 
because they are all on a sphere rather than a grid - are you taking the 
spheres normal into account regarding the orientation?  And as for OP, Morten 
am not sure why your orientation is having the effect it is, perhaps because 
you are setting the orientation only on emit then doing something else that 
effects it. try putting the orientation back on as the last step in the ice

Re: ICE strand orientation trouble - again :/ now with images

[Rob Chapman]

'a technique I came across somewhere'  oh! , sounds a bit like this
http://sites.google.com/site/tekanoice/tutorials/ice-flowers-part-i

;)

heres the scene file from that tutorial

RE: ICE strand orientation trouble - again :/ now with images

[Sandy Sutherland]

I can send you a scene I developed based on a technique I came across somewhere 
to do awesome simulated strands, by creating particle systems to loft the 
strands between and doing the sim on the particles - this allow you to set 
orientation on the particles and then the strands - I was using it to do grass 
and bushes being flattened by a vehicle and I had the bushes/grass randomly 
oriented as I was rendering a field using strand deforming.

Re: NURBS import

Hahahah - sounds like the Autodesk® -Approach® : instead of fixing the ever

Good® stuff®! ;-)
