I'd like a shimmering material, kinda like a disney dress type shimmer? I've been experimenting but have had little success. I've also looked around on the net and found this one http://www.hash.com/forums/index.php?showt...rkling+material but the link to the material is dead. Can someone help me out? Thanks

Can you post an image to show what a "disney dress type shimmer" looks like to you?
Also perhaps show what you've already tried and what you did to get it. -------------------- |

I recall it was damn difficult to keep the Scarecrow's hat from sparkling in TWO.

On the very off chance that you may be looking for a shimmering scarecrow hat type material look:
The hat was decaled, with both color and bump maps (vary the percentages and images/patterns used to taste) The specular property in the surface settings for the hat were set very high (300% spec size, 300 % intensity). To vary the look, vary the percentages of the spec size, intensity as well as spec color. To see the effect rendered, at least one light in the chor must have the specularity option turned on There are other ways to get shimmery. Just depends on what you mean by "shimmer". (eg with Bit map plus material, or gradient material or roughness property)

Thanks for the reply Nancy! Lots of good stuff. I am wondering if that pic you linked can be used by the community? I popped it on my model to see how it would look. You don't mind do you?

Yes of course, use it. I consider that any assets (projects, chors, models, etc) that I upload to the forum are available for others to use. The fabric works well on her. Nice model. So I'm gathering that the shimmer disney material quest is now done? -------------------- |

A noise combiner used as a bump that would create many flat, angled facets might make a reflective surface sparkle as it moved.

experiment with noisy sparkly thing

Nice robcat!!! How about a download of the material or a pic of the material makeup?

Remember this isn't a one-pass solution.
I couldn't figure out how to quickly make a material that that would create flat, randomly slanted facets when used as a bump material so i painted a bitmap to do that. I applied that as a patch image to the whole model, set it to bump, set the repeat values to 3 and randomly rotated it on several patches so the repetition of the texture would not be so obvious. I set the model to black and the spec color to white so the only visible detail on the model would be the specular highlights. Because the surface is a bunch of flat facets and not a continuous smooth surface, each facet must be at a particular angle to the light to show a specular highlight to the camera. As the model turns the angles are constantly changing and different facets show them selves. I used the Glossy Specular shader so that each highlight would be white with no soft edge. This makes each sparkle be either on or off. I made another render of the model with the texture deleted and a not-black surface color and compositited the black with white sparkels pass over the regualr render with a "lighten" compositing mode in After Effects.

Nice! I like how that looks
Another variation (all done in A:M): took your original vase, made it 98% transparent, called it outside group (left the patch image) duplicated the vase shape (scaled it to fit within outer transparent shell) and called it inside. Cylindrically decaled it with a bump design 20% (chinese material), and color map. Gave it a spec color of gold, 100% size, intensity, but used regular spec shader, deleted patch image. Got more of a glitter effect (on the outer shell), as the glossy spec shader works differently when the surface is transparent. It might look nice to have transparent cloth glitter dress, and have the body deflector part decaled EDIT: changed screen grab This post has been edited by NancyGormezano: Dec 8 2011, 04:01 PM
