M-Forgeless

I have had this idea for generating a multi-layer paint effect in EIAS without mforge (which IS fantastic).
I finally got around to trying my idea.
Here is the first test. It seems to be relatively successful.
This uses no third party products.

Comments and critiques welcome.
(There is a small tesselation prob on one of the shapes so be gentle.)

That's pretty slick! What's the trick, if you don't mind sharing?

Sure I can share!
I am using the gradient shader set to "view edge" in combination with the anisotropic shader. Two colors come from the gradient shader, and one from the anisotropic.

If anyone tries this, or figures out another method, please post your results!

Qt 6

Dave, any chance you can make your movies viewable to people who don't or can't get to QT 7.

Don't mean to be a pain in the butt... I just can't justify the expense to upgrade my home machine, Mac G4/400/OS 10.2.8, at the moment. The QT 7/iTunes download from Apple causes to many of hassles on my employers Dell machine config and is basically against company policy to install it.

I'm starting to feel like the Lowest Common Denominator.

Thanks,

Mike

That is indeed very cool. Thanks very much!

Very nice indeed!

Mike,
you are in good company
Someone else needed something for an earlier version too.

Try this (compressed with Sorenson 2) it should work. I don't have QT 6 to test with.

Also, here is a JPEG Just in Case.

If anyone experiments with this please post your experience/ results.

Yeahhhhh, very cool.

I use this technique when ever I get MForge nosebleeds - this happens to me if I ever need a material that isn't a preset

MForge is spectacular, but I swear that shader should have a 'sandbox mode' with only the simple controls, or at least a hierarchy of complexity (so the more advanced stuff is hidden and revealed with a click).

Sorry for flying OT there
Good work Dave !

Thanks Ian.
I would love to see your technique with this if you care to share!

Thanks

Hi Dave,

Thanks for updating the the quicktime movie and telling us how you used the shaders.
I hope to do some very simple experiments with this over the weekend.

Mike,
Looking forward to seeing your tests!

some experimentation

Hi Dave,

I did do some experimentation with the gradient and anistropic shaders but I don't quite understand how they work yet so I'm still experimenting/exploring/learning the material/shader ropes... oh and add in some lighting learning to that too.

...I did notice your post on the material library... the examples at the EIAS forum are quite clear, and the scale of the shading is good... I think that may be one of the issues I'm having with my experimentation... I think I have a disconnect with the shader settings and the scale of the spheres and block I'm using...

Would it be ok if I worked these issues in this thread or would it be better to start a new one? I do have a lot to learn on these issues and my time with EIAS is spread pretty thin so it could take a little while to work through...

Thanks,

~Mike

Hi Mike,
I think this forum is an appropriate place to discuss this technique.

Please let me know if you have any specific questions on the setup for this effect, or post links to images if you have some work-in-progress samples we can talk about.

As you pointed out, the lighting is half of the material equation.
I have had very good results by placing a single radial light at about 60% intensity at about 45 degrees to one side and above an object (sphere) resting on a flat plane. Then turn on GI, and set primary rays to 50, secondary to 0, enable skylight On, at about 60%.
Then tweak it a bit to taste.

a little progress...

Hi Dave,

I've been putting a little bit of time in on this in the early am, late pm and sometimes lunch at work. I'll emphasize "a little bit of time", I've spread my art dabbling time a little to thin among to many art ideas, concepts and projects.

I've posted an image of where I'm at. I've basically been exploring how the shaders work with light and trying to understand them. So I made a gradient model, anisotropic model and will make a third model to show them combined.

From what I've explored so far, both of these shaders seem directly dependent on the light source for how they appear. I was assuming they would become the overall material, but my images show otherwise. I'll be changing the model diffuse color to work better with the shaders.

I'm using Light rig, a radiall light, EIAS modeler 5, EIAS 5.5.3, I also downloaded the EIAS 6.6.x demo here at work for lunch time experiements. My Dell M70 laptop at work blows the socks of my G4/400 for render times...

Well on to other things... Thanks,

Mike

Hey Mike-
Thanks for the e-mail.

I think you are headed in the right direction!

A couple of tips for moving forward...
Just select the Anisitropic shader you have on object two, copy and paste "on top" of the Gradient shader on object one (both in the diffuse channel) so both are active on the same object. You should try increasing the intensity of the anisotropic for a bit for more contrast.

Also, try some crazy color combinations. Maybe color the object yellow or green, keeping the blue gradient, and maybe an orage-ish anisotropic. Experiment and have fun!

Light Rig is great, but I really can't say enough about how great GI is in 6.5. If you get the cash together it is a worthy upgrade. (I am sure it's tough on "hobbyist" users.)

Post again when you have some more previews!
