Warning: Triplanar only supports bitmaps

[MANUEL_MOUSIOL]

Sometimes I get this error message Warning: Vray Triplanartex only supports bitmaps during GPU rendering.
I am pretty sure I have nothing else in my triplanar maps (why would I?), but maybe I combined it with another map and vray doesnt like that?
It would be great to know to which triplanar map this error is refering to, so to find the culprit easily.
With so many materials and textures in my scenes, it is a lot of work to find the problem.

I find that in general the error messages help little, as they are not specific enough. Then they go up as more messages come and I cant go back to find out what to fix. Have to sit there and take screenshots while messages pop up so I can later go and fix stuff.
Is the log written somewhere? Could we have a saved log file in the 3ds max folder, please?
Some buttons with the error messages that lead to the map in the material editor, or select the object that made a problem would be a dream.

Devs, what do you think?
i usually combine a colour correction with the triplanar and rendering works fine but the log is flooded with warnings...

[Muhammed_Hamed]

I get this error quite often, it really doesn't mean much
like you said, if you have a color correction node plugged in the triplanar for example, the warning will be printed.. but nothing really happens and it renders fine
What wont' work is connecting a normal map for example to triplanar or procedural texture like bercon noise(which you don't really need to do)

[MANUEL_MOUSIOL]

Yep. These warnings fill up the log though, make it hard to read and then there are other errors which will quickly be gone. Everything is going to fast.
that's the reason for my request for a better log system.

Yea same here

[danio]

Yep, same here. Makes the log more or less useless (and a little annoying unless minimized).

Can you show us how your tri-planar shading graph looks like ?

Hi Vladmir, I don't remember exactly which shading graph that was but I always use something like this:

Bitmap -- Output -- VRayTriplanar or Bitmap -- Output -- Color Correction -- VRayTriplanar

Hi Vladmir, I don't remember exactly which shading graph that was but I always use something like this:

Bitmap -- Output -- VRayTriplanar or Bitmap -- Output -- Color Correction -- VRayTriplanar

Why not use Bitmap -- VRayTriplanar -- Output -- Correction ?

With you setup, V-Ray will have to compute the "Output -- Color Correction" part 2 or 3 times for the parts where the tri-planar projections are blended.

Oh I see, that makes a lot of sense. Thanks for the info.

I also use them a lot in composites. When using several of them layered in a composite, I assumed it'd use less resources to put the triplanar after the composite, and control the size with the tiling in the bitmap, instead of using 3+ triplanars in one composite. (saw that in one of Adan Martin's videos if I remember correctly)

If that's the case, would it be possible to clear that message from the log in that scenario?

Thanks

In that case, I am not sure which will be faster.

If you have
Bitmap(multiple) -- VRayTriplanar(multiple) -- Composite
the triplanar texture has to be computed multiple times, depending on the number of Composite layers.

If you have
Bitmap(multiple) -- Composite -- VRayTriplanar
then the Composite texture might have to be computed 2-3 times, because of the triplanar texture it's inside.

If that's the case, would it be possible to clear that message from the log in that scenario?

Sorry, I can't say about this. Somebody from the V-Ray GPU team can answer whether this restriction can be removed.

I am interested in this because of our project Lavina, for which I am doing the texture evaluation code, which is similar to V-Ray GPU, but not quite the same.
