Issue with maps directory after Vray 6.2 update

[fran_ter]

Hi,
I have upgraded Vray to version 6.2, but once I reopen the projects I was working on, many material maps results missing.
Reconnecting the maps wouldn't even be a big deal, but the trouble is that all the color corrections associated with those maps are gone.
I don't know if it's related to this problem, but Vray File Path Editor reports the following warning: "Unexpected error occurred: TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined"
Has anyone experienced the same problem? Any ideas on how to fix it? It seems that the error is only related to materials from Chaos cosmos and only to diffusion maps (reflection, bump, etc. are fine).
Thanks in advance for any help.

Hi fran_ter,

Can you share the project for testing on our side?
Also, what kind of color corrections disappeared on open - V-Ray ones or SketchUp colorization?

I had the same problem, and I had to reinstall the previous version. At the moment, I haven't found another solution. I am very interested in the result of this analysis. Greetings

I'm sorry, I cannot share the file as I "fixed" the issue by downgrading to update 1.3. However, this is not a problem with this project, it happens on every project and for all materials originally coming from Choas Cosoms. The color corrections that disappears is the one from Vray and in its place I find only the screenshot I forwarded in the previous message.

Thank you all for reporting this issue!
Our QA team managed to reproduce it. The Dev team handle it with elevated priority.

Hi fran_ter ,

Can you still share the file?
It is even more useful if we get the one saved with 6.1 since we'll be able to see the source of truth.

And one more question:
Which color corrections are disappearing - the one from the SketchUp's material panel or an actual V-Ray Color Correction map wrapping the bitmap?

Thank you in advance,
Konstantin

Hi,
As I mentioned it is the actual V-Ray Color Correction map wrapping the bitmap.
I didn't save the file after the error, I just checked and the problem was common to any other project and - though I'm not 100% sure - affected only the materials downloaded from Cosmos. The main problem I think is with the path of the diffusion bitmap that was being laced into a nonexistent temporary folder. The reflection maps, bump, etc. were ok and were being found.

Hello guys

Today i have time to install and try vray 6 update 2

I come from vray 5.1 in which i dont have chaos cosmos material yet.

I use a lot the wrap in color correction for a lot of scenes.

Is this happening with just chaos cosmos materials??

Can you share a screen shot what really does this new update in textures?

I read too that this is happening in just the diffuse maps

If i created my materials with the color correction wrap in im going to see this issue?

I read too this is happening too in vray for rhyno

Thanks

Hi guys,

The issue with the disappearing textures (it isn't just color corrections) has been identified and we have a fix for it.
The problem has to do with the new texture baking system we introduced and a case we missed when activating specific scenes.
We will do our best to provide builds with the fix as soon as possible.

This issue is serious and obvious at the same time, so please accept our apologies for not catching it before the release!

Best regards,
Konstantin
