Re: Diffuse + Specular = ?
you can measure most of this stuff. diffuse and spec can be picked up by a camera with a polarizing filter. gloss can be measured with a glossmeter or a goniophotometer. and yeah, this kind of data already exists and is availible for a large range of materials. here's a sample of blue acryl paint. and yeah, it's useless.… -
Diffuse + Specular = ?
Hey guys. I'm having a bunch of trouble with defining materials. I've watched loads of tutorials and read up on spec maps but I end up picking my colors/values through trial and error. I don't understand how the two maps work together to produce the final result. Is there some kind of formula that shows X + Y = Bronze (or… -
Re: Diffuse + Specular = ?
The best way to understand materials and material definition is not by a formula or X + Y = Z or following a guide, its by observation. It is honestly the best way to understand materials, how they react in the light and understanding what is causing that effect. Its more then just looking at something and being like, oh… -
Re: Diffuse + Specular = ?
Could you explain this a little more. Have I been inverting my specs this whole time when I didn't need to? -
Re: Diffuse + Specular = ?
Thing is that the whole hue-shifting 180 degrees is not necessary anymore with shaders like mine or 3PS, so don't get confused with that... -
Re: Diffuse + Specular = ?
The tutorial PhattyEwok posted is pretty awesome. Definitely sent me in the right direction. Using that, trial and error, and close observation of random objects should help. -
Re: Diffuse + Specular = ?
This is an awesome article about spec maps and how to implement them. http://www.manufato.com/?p=902 -
Re: Diffuse + Specular = ?
I was looking for a thread I saw on here that talked about the actual molecular propertis of gold. and why it looks the way it does. but I found this http://www.polycount.com/forum/showthread.php?t=56483&highlight=material+definition+gold+reflection has some good stuff. if anyone knows what Im talking about please help me…
