Maya2014 Vray 2.40.02 Shave 8.0v39 - VrayRE diffuse problem

[Adbk]

Hey guys...

Can't get the vrayRE diffuse channel to render correctly. Using VrayHairMat3. Most other channels seem to be ok.

Using Maya2014
Vray 2.40.02
Shave 8.0v39

any ideas? Was this fixed in a nightly?

thanks

[Adbk]

another note- just tested:
Maya2012
shave 7.034
vray 2.4.02

its still buggered.


It DID work in vray 2.25 build... but we don't want to roll back as we are experiencing a 6% speed increase by using the latest versions....just missing the diffuse channel...

any help would be much appreciated.

thanks

It works fine with the latest Nightly Build (2.45.01)
The speed increase might be because the diffuse was not calculated - try to install the latest build and run another test.

Thanks for the response... we will try the latest build

I figured that the time discrepancy may have been the result of that...we will see and I'll let you know the result. Thanks again!

I have the exact same problem, vray 2.40.2 and yeti, seems vrayhairmat3 doesn't output diffuse information. this was fine with 2.3.
The other problem (which I think is related) is the hair3 color/texture is missing in lightSelect channel too.
I would like to try the latest nightly build, where can I get it please?

Hi,

Please send your request for V-Ray 2.x for Maya nightly access directly to our sales team : sales.software@chaosgroup.com and they will assist you.

The other problem (which I think is related) is the hair3 color/texture is missing in lightSelect channel too.

Yes, it is a known bug and our developers are working to solve it.

Thanks a lot, I got it.

I tested the latest nightly built and it seems it renders the VrayHairMtl3 shader entirely different, particularly I get a strange specular , very bright and sharp and the overall look doesn't match with the 2.40 version. should I open a new thread or is there a place to report issues with nightly builds?

I just did a quick test using both V-Ray versions and got identical render results. My scene is very simple so it will be better to see your file.
Could you attach it here? Also please post your render result if possible.
