Some of the textures will work fine when they are in Explicit Mapping mode (i.e. Cellular, Noise, Smoke etc). In that case they will be baked as bitmaps and sent to the GPU.

Hi Vlado,

I tested Noise in Explicit Mapping mode and and it kinda works, however I have to crack up the value 300% to get a similar results to production. Cellular did not work at all. am I missing something?

4

Is this for bump mapping?

Best regards,
Vlado

5

Yes I tested it in Bump mapping.

6

Hm, can you get me a scene then?

Best regards,
Vlado

Simple test i did.

Hi,

Thanks for sharing the file, it seems that V-Ray RT/GPU has some issues with 3DS max bump slot when Cellular, Dent, Mix, e.t.c maps are set there.
I will make a note about it.

Thanks Vlado for reply, didnt know that.
Bump bug is worse, can you fix that?

10

Explicit mapping works, but it has all the bad things UV mapping has. 3D procedural need to stay 3D procedural.

Hi,

Bump bug is worse, can you fix that?
We ware working on this, i hope to have full support for the Bump slot in the next release.

Any updates on procedural maps?..The last service pack did not include any procedural maps updates. Also Vlado mentioned at Siggraph the they will be some “nose specially” included in V-Ray 3.0 however I do need see any updates on procedural maps in the 3.0 beta.

The procedural noise is there actually, we forgot to put it in the changelog. We also have VRayDirt support for use with the ExtraTex element, but when we tried to support it for materials, the whole thing became like 30% slower whether you use it or not… it is frustrating.

Best regards,
Vlado

Thanks for the update Vlado,

Could it be possible to have a procedural map switch? even if its 30% slower it would defiantly help to have it as an option.

15

Will see if we can do that. In fact, I’ve been thinking of introducing several different kernels, with varying degrees of features vs speed; f.e. one that just does a grey material on everything, or one that only does direct lighting etc. We’ll see.

Best regards,
Vlado

That would be great!
I mainly use RT GPU to set up lighting on interior scenes, it’s also very helpful for making materials even at a slower speed in a open studio setup RT GPU would still be significantly faster than CPU, especially with the newer graphics cards now supporting 6 to 12 gigs of ram at insane speeds.

Thanks!

The procedural noise doesn’t appear to work in the bump slot.

Hi,
This is a known issue (it will not work for any procedural map actually).
We do have working a version of it internally. I hope it can make it for the final version, but I can’t promise (we have to find a proper way to do it in order to avoid slow-downs even on scenes that are not using noise/noise for bump).
Best,
Blago.

Ok Thanks…It would be great to have, maybe as option, different build perhaps? even if its slower it still significantly faster than CPU…I’m sure a lot of us will be ok with a slow-down hit.

Hi,

Unfortunately this implementation is not part of any builds yet.
We will update this thread as soon as we have it available for the nightly builds or 3.0 beta.
