Thanks a million

Thanks a million - the shaders do look cool. One thing I have to say altough it happened on 8 and I don't use Mental Ray - we are very lucky to have unlimited render nodes. I just worked with a Maya guy who used Mental Ray on a project and screwed himself with node licenses - cost a bloody fortune.

we are lucky adam. It will be interesting to see if the pricing for render nodes drops with this new release

well mental ray network rendering is free and unlimited now, even DR, i read somewhere.

Oh and I cant wait to see people start using the dirt pass in their workflows. Its totally changed how we do things where I work. I absolutely LOVE creating low quality, very blurred irradiance maps that render fast, render with NO blotches or noise, and just use dirt pass for the finer GI shading.

could you eleborate please ? seems hot though I do not really understand. thanks

you can use a rather low res irradiance map, but blur the irradiance map using interp/hsph samples or whatever, to get a nice smooth map, it just doesn't have alot of the finer details. Those are created using the dirt map, which is fast to render and very easy to adjust.

I really like skylight attached to time and location function, we shouldn't be engineer to understand sky's turbidity, ozone levels ,

Simplicity of architectural materials are also great Vray team can add those easily

I always feel like an engineer rather than a designer while using vray

Muzzy,
The way I understand it (correct me beta testers) is that if you leave the default values of the vray sun/sky system, vray automatically makes the sun/sky act correctly based on position of the sun in the scene.

What you can do is put Max's sun/sky system in the scene, turn it off, then use a position contraint to lock the vray sun to max's sun. That way you can set the position and time of day of max's sun like in the video, and the vray sun will move with it.

You can already do this in previous versions of Max using the Daylight system (instead of the new MR system coming in 9) or wih the Photometric Sun.

So, they're just adding a third way to do the same damn thing instead of enhancing the old ways....

So what your saying is that AME is just trying to polish a turd?

That´s basically correct, the nerds can read the paper (Preetham et al), as a sidenote for the non-nerds : This isnt actually a physical calculation, this is a physically based ANALYTIC approach. Basically that means, instead of calcing the real light scattering in the atmospheres, there ewre formulas developed that mimic real life behaviour. There´s a lot of things left out, like pollution, localised differences etc etc...but it serves the purpose pretty well And it´s bloody fast. plus it can actually be seen in the viewport (just turn on "use environment background"). That´s great to play with and find the right position/settings

yeah. i think terragens sky is actually one of the better ones ive seen due to the insane amount of peramiters you can choose like haze and polution and half light etc. maybe someone more versed in the different programs out there can tell me if its using the same principle as vrays and maxwells yet giving way more peramiters

[jacksc02]

polished turd sounds about right!

Thanks gilpo, didn't know that. I will try it

I quite like terragen looking forward to seeing what the new vversion will be like.
