RT GPU: Procedurals in Bump Slot

[super gnu]

ha.. thats the first time its ever been explained to me properly, the reason why bump mapping has "quirks" in max.. is this still the case when using the vrayhdri loader? i guess so, although i have noticed a nicer bump result from a vrayhdri in the past.. thought it was my imagination.


so, anyway, to get a slower but more accurate result, similar to maya, i should use color2bump between my map and the material? (sorry blatant thread hijack)

I found color2bump really doesn't work good on RT, straight bump is better but still gives pretty wrong results.

You could do that, yes... but it will be a tad slower.

Hi Vlado,

Just curios here...when the V-Ray Material editor came out I remember seeing Max and Maya map working in it, are these Tex maps Vray created maps? could we have these in the maps outside of the V-Ray Material editor and use those in the Max standard material editor?

I remember asking you about the TexCloth map and and you said you could get us that as a standard map outside the vray material editor but that was a few years ago and it has not made it to yet.

Could we use Vray maps oppose to the max one one if V-ray has it own procedural? I'm guessing that's what those Tex maps are in the V-Ray Material editor. but that me just speculating

are these Tex maps Vray created maps?

Yes they are procedural V-Ray Maps.

could we have these in the maps outside of the V-Ray Material editor and use those in the Max standard material editor?

As for now no, they could be used only in V-Ray Material Editor. They could be ported to 3ds Max material editor as Vlado mentioned but I guess that this is a bit down on the to do list.
As a last resort there is always an option to bake texture to a regular bitmaps.

Actually I've been thinking of exposing some of the V-Ray maps, in particular the Noise and Cellular textures since our implementations have some advantages over the 3ds Max ones. Looking the same in the regular V-Ray, V-Ray RT and V-Ray RT GPU is nice of course, but they are also somewhat faster and produce more accurate bump mapping.

That would even better than then get the Max maps working on GPU. I always prefer to use use Vray maps/shaders i.e, Vrayblend, VrayNormal ect..

I hope this happens.

Thanks!

Ah haaa,
Yes sure, I'd much prefer to use vray's maps if they work everywhere and are even better (speed, settings, look, etc)

Would this be something hard to implement? If you metion "expose" I'm just guessing it wouldn't be

That would be nice!
A few things would be missing for the noise though, especially the fractal and turbulence modes, as well as the low and high threshold. And a function to distort the noise with another map. If these are put in, it's superior to any other maps like bercon out there, and it would look the same across platforms.

Why would they be missing?

Well, I could not find any corresponding features in the TexNoise of the VrMat Editor. I tried the parameters, but I couldn't really get anything like fractal, for example.

That's a different noise texture We have a bunch of noise textures in the SDK; we have one that corresponds to the Max noise (we use it for V-Ray RT) and it has all that stuff (minus the distortion, but that could be done).

Okay, that is great news! Looking forward to it! Didn't know there was more.

Vlado has always a little something he hides from everyone under his elbow, and then TADAAA

Would be a real benefit to have all those maps exposed in max to have a seamless integration of those procedural maps across all the render platforms

Today I tried to convince the Cream guys that RT-GPU was better than Octane, then I realised it supports zero procedurals
It hurts
