VrayTriplanarTex: Integrate into ScannedMtl?

[Ivaylo Katev]

yes, the latest nigltly is from june, the stable builds are running, but they are not including new features
of course, at some point we will restart the nightlies, i think it's not so far in the future.

So to get the triplanar scans, I'm still confused as to which one I need to download. The only thing I see that has a current date on it, are the stable builds.

Sorry, I must be having a brain fart, haha!

I tried using triplanar with car paint vrscans but I still get strange dark areas. are there materials that work better than others or is the feature in general not yet well implemented? (using vray next beta 2, nightly from today)

[Ivaylo Katev]

can you share some images or a scene?

[MANUEL_MOUSIOL]

Here you go. A normal material works fine but vrscans with a carpaint and triplanar enabled looks like this.

[MANUEL_MOUSIOL]

btw, triplanar tex with a regular biitmap works fine too

So far I didn't have any issues with the triplanar option in the VrScans. I rendered at least three dozens of images with that option.

probably there is no problem with most surfaces. What I am working with right now is converted CAD data, which seems a little dirty on the modeling side here and there. Thing is, probably properly mapping the whole thing would solve the whole problem, but I am lazy and very bad and slow at uv mapping and would like to use triplanar mapping with vrscans just as I would with my own materials. And seeing that triplanar mapping in general is not a problem with this model either, I would expect the same with vrscans...

[Ivaylo Katev]

can you prepare a small piece of this geometry to test with?

Well, my work here is no exception, geometry converted from Catia without any UV's at all. TriPlanar works like a charm.
I am pretty confident that Ivaylo can figure something out.

[MANUEL_MOUSIOL]

Here is a piece.
CPU rendering works fine, GPU leads to the problem

[Ivaylo Katev]

thanks for the geometry!

[MANUEL_MOUSIOL]

Ivaylo, this problem is still there. Can you resolve it?

[Ivaylo Katev]

I have to check what is happening, because the GPU part is implemented by the GPU team, it's quite possible that the issue is not in the system, i think i tested it, but i'm not sure. I will tell you more until the end of the day

[Ivaylo Katev]

Unfortunately we were unable to find the issue in the system, that's why the bug is still not fixed. It is well pronounced and easy to demonstrate with your geometry, so i think the fix can be expected until the end of the week.
