Hi all,
I work to create a scene for materials for EIAS and imediatly use into.
I will share the EIAS project and I hope that the support of EIAS create a section dedicated to the exchange of material preset based on my work.
Some work examples in making
I hope to end soon the project and to share it with everybody. I would also want EIAS to create a section of exchange of 3D fact models. with the release of the project of exchange material I would want to start a small portal for the exchange of models 3D and to induce eias group to insert him on their site web.
Superb - exactly what the EI community needs. Things are really coming alive for EI these days. I’m very excited - but then again I’m quite excitable !
Perhaps we can have a standard which includes not only a few shapes, but a few scales as well. Some textures work great on the scale of a ring and not so great at building scale.
I would suggest a small, medium and large designation (measured in EI units), and further I would suggest three shapes (perhaps a sphere, three walls of a cube, and a cone… ) When the model types and scales are agreed on, the project file should be made available for download, and people can submit their materials with renderings based on the project.
It would also be nice if the section we upload to were divided by material classes: stone, glass, metals, etc.
I’d be willing to render out the materials supplied by EI for the forum once the standards are set.
This is such a good idea, let’s not let this thread die!
Check out the attached link to one of Maxwell’s material previews.
It has some detailed lettering beneath the surface to show a material’s translucency, transparency, and refractive properties.
These kinds of features would be very useful for the EIAS material scene.
A couple of comments…
I really like that you have a color reference bar.
Scale was mentioned as an issue.
Perhaps the ground grid could be set to different increments (and show some subdivision) for different scales (mm, Inches, and Meters?)
Just so the scale thing is clear, I’m actually suggesting three renderings per material (S,M,L). A texture that looks great small, may look wacky on a big surface. Though you can scale textures, some have multiple shaders to change, and you might get closer to a larger scaled object, where the texture may fall apart. Of course that adds a level of complication to building the library… People hate that.
On the grid topic it would be good if there were a rainbow band as well, to show color shifts.
It would also be nice if we could replace the material preview in EIAS with these images… drag and drop.
Here is an idea of how the grid might be subdivided and labled for scale using decimal units.
(the inches/feet version would have 12 subdivisions)
(I think the grid shown on the sample is subdivided but it is very subtle)
I think it is very important to use some real world units for the material scale factors.
I would suggest mm, inches and meters for the small, medium and large units (1:25.4, 1:39.37, and 1:1000).
If all materials are open source, then the community could help to create the various scales once a new material was submitted.
I think the addition of a full spectrum to the CMYK samples is a very good idea.
Very good idea Dave.
If you want finish the grid, subgrid, scale, units and color ramp in CMYK and RGB.
When you have a finish project send me it and I want to insert it in my work-project.
Thank you for your support.
The unit should be in EI units. If I recall the scale of your project is set to what ever the unit you exported it in. So one EI unit is equal to 1 inch, or 1 foot or 1 meter. What ever your project was exported in. I haven’t noticed this changing on imports into EIAS 6.5, so I assume it’s the same. That means scale is always relative to the EI unit with regards to texture size. Many users have set up there exports to be consistent, in yards or meters for example. So to keep the material library consistent, the only know unit would have to be the EI World unit…
It had been suggested in the previous EI forum, that we have a way to scale textures in the material dialogue window. I don’t think there is a way to do it yet.
