Next time I talk to Renato I’ll see what we can do about getting this shader into VRay.

Hello to all!
Stefan i want to ask: have vrabridge support VRay2SidedMtl, VRayOverrideMtl, VRayMtlWrapper, VRayEdgesTex, VRaydirt and other vray-“shaders” or material tools? (updt.)
For example cinemaxwell has metal, diffuse and other it’s tags for “native” determination…
Ilay.

no,
we use c4d material shaders.
vraymatl wrapper function is used to make all c4dshader work.
almost all funtions are in c4d anyway.
we probably will add some of the shaders in future updates, but most things are better in c4d shaders actually, the c4d shader system is very strong.

Thanks Stefan!..
It’s nice to make bridge so close to cinema4d, then it (maybe) will be native render in future :applause:

#1545
a little correction stefan,
the vraymatl wrapper is not used in our bridge. The connection is directly with the c4d shaders and all others external shaders plugin (made in standard way) 
Cheers

Hi to All,
this is a new image made with vray for c4d.
In this image the GI calculation was made in low resolution(1024), saved and recovered for the hi resolutio image calculation (3000x1875)
Redertime
4min for GI
and 70min for rendering
This is very usefull tecnic for limit the render time without quality reduction.
hope you like it.
for hi res.

You combine 2 pics: gi with low-res and “simple” render-pic with high res-n?
This technics is like final render or cinema’s ar. This is not surprise.
I think that vr4c4d will be more comfort…but it isn’t…
What so dark shadows of plants? What is glass-door’s material? Why i can’t see lights from lamp, only ies-highlights on wall?
Sorry for this…
Thank you for sharing this pic.
Ilay.

I don’t think he combines two pictures. What he does is have VRay calculate the GI on a faster rendering lowrez version of the scene, save these data and then use them on the fullrez version.

ohhh Francesco i’m sorry!!! I forget about vrl- and vrmaps!
I’m being head over heels in work…
Erik thank you for correction my mistakes…

Stefan’s idea being that you can render the image very small and save the IR map, then use that map with another rendering that is much larger.
Actually, this isn’t really necessary as Vray will allow you to render just the irradience map and then save it for later use. The IR map is actually resolution independent. It’s jut a collection of points in space with Irradience values at each one. if you want to save time, just cut you Min and Max Hemisphere subdivision rates down to something like -4 and -2 and you will get the same results. Of course, this sacrifices quality but so does Stefan’s method. The main reason you would save an IR map is to use it in an camera fly-through animation. This reduces the time it takes to render each frame because it simply loads he IR map instead of rendering a new one. But normally, you wouldn’t do this in character animations as you need the IR map to change as the character moves around in it.
[ edit: I just noticed that it was Francesco and not Stefan. Sorry about that. ]

"if you want to save time, just cut you Min and Max Hemisphere subdivision rates down to something like -4 and -2 and you will get the same results. "
ngrava what you say is not right, sorry,
(this method is also not my method, it used by most vray professional):
it is NOT the same to render the image at high resolution with lower setting! thats the point, that would sacrify quality.
the method has no visual loss in quality, you even get a much better GI solution normally when using this method correct, than render at full size with lower settings.
the point is to render a very detailed IM map with many passes like -3 /+1 or (even higher, important also is to use as many passes as possible) . this map you can render at low resolution, but you get a much better light distribution and very nice gi shadows. you can use this saved IM map then to render any size, very fast and you still get that pronouced GI solution.
if you render a high rez image with -4/-2 you just get a low gi quality and it takes even more time…so dont do that.
of course you also use saved maps for animation, but that of course is not the only use.
the above method is not necesarry, but you get higher quality and less time. thats why i tell this method here as a great variant. it gets better results, no loss at given time.
cheers

Could we see an animation one day?
It’s the only way to see the real issues. I want to know if VrayForC4D can generate a consistent indirect illumination from frame to frame, if its anti-aliasing is smooth enough to avoid flickering and excessive noise. Rendering speed is also a critical aspect. It must be fast. I’m not interested in a 2 hours per core/per HDTV frame scenario. I’m also curious about the motion-blur.
An animation is actually the first thing I want to see from a rendering engine.
It doesn’t have to be complex stuff. A simple fly-over (slow) in a scene with a generous amount of reflections and transparencies will do.
Thanks!

yes vray can do animation very good and very fast.
sorry i didnt have time this week, was a bit ill too.
but in meanwhile you can look also for any animation made with vray out there. we use the same core.there are many many extreme good ones made with vray.
rendertimes of course depend on scene, but are, as the rest, faster than in other apps.
with MB i am no specialist but i was told also MB is superb in vray.
we will show animation before release too. reflections and transparency do not slow down vray much by the way.
cheers

Now slow down? that sounds great. Where can I find good animation samples done with Vray?
Peace,

not much slow down…
almost all good archviz animations are made with vray p.e.

[QUOTE=lllabthe point is to render a very detailed IM map with many passes …cheers
stefan[/QUOTE]
from what i have read of the documentation mutipasses is tied to the number of cpu’s being used to render. For example for a single cpu it is suggested ( in the documentation) to use a single passs

Hello to all!
It’s nice to read. I think some nice anim-s(outdoor scenes) are made by vue xstr/inf.+any good compositing programm. I watch a few animations and our studio make some(for arch-viz), skyline-render is faster than vray in 3dsmax :))), so i wait it to trying in cinema4d…
