Just noticed that too, no it isn't. Theyre showing differently in C4D:

 I don't know enough about these materials to know why this set of them would be any different, I'll submit it now just in case. Some are fine and some aren't.

I tried a bunch out.  even the few that are not black - and something seems to be not right with those resources.

I think the sample file I was using is quite old, as per a comment from @Kevin McAllisterI sent it on to Engineering to confirm whether its something to do with the updated reflectance shaders or something else.

Apparently the black importing textures were indeed affected by a limitation in which portions of CineRender R16 we can use. Among them the Reflectance channels @Kevin McAllistermentioned. I will try to get a whitepaper together to detail anything else that may behave this way.

Oh, so any textures we use have to be for C4D R15 and older? Reflectance replaced a whole lot of stuff in C4D R16.... so most modern C4D textures (including the Greyscale Gorilla ones) have been updated to use Reflectance.

Not sure. I''m going to talk with the rendering team to get a list of any known limitations together.

Actually, stand by, I may just be dumb. Apparently there is another method of saving C4D file that includes associated resource and when I made this sample I did not do that, so the sample C4D file I posted does not have the image shaders or other guts that Vectorworks would need in order to display them properly. I'll do a writeup of all of this as well as a suggested workflow for getting the materials from C4D into Textures in Vectorworks. If I have posted erroneous information before now I apologize, I'll speak on this again once I get cleared up.

@JimW- Have you had a chance to clarify & put together a write-up of the suggested workflow for using C4D textures in Vectorworks? Thanks.

No, I have yet to get a definite explanation that I understand well enough to convey the information to users.

You can import any C4D File by import C4D "Textures".

If it contains standard C4D Materials (no VRAY Materials) it will create a Ressource Folder in your VW file

with the name of the C4D file and load these in.

If you have already "RW Textures" with same names, it will change the name to "SameName-1".

 

It will load in Image Textures and standard Material values.

All 4 VW Material Channels will be set to "imported" but can be changed and edited.

As C4D Materials have no Texture size, that happens there with assignments per Object later,

you will have to check and assign a proper "RW Texture" size.

 

If C4D Materials used any Reflection Shader other than "legacy Reflection", you will not notice in RM Preview

but these will simple Render completely black. In this case you should change the VW Reflection Channel

from "imported" to any suitable RW reflection type and it should work.

@Tom KlaberSome engineers are taking another look at this, one or more of them may request access to the google drive link you sent me for testing.

And now one of my folders is spammed with pictures while I was expecting one video file... oops xD
