Solid projection for procedural textures

[lopez67]

Hello,
I used Modo for rendering. There is a projection-type for the procedural TEXTURES named "Solid projection", very useful to me. There is something similar in Vray (no triplanar map), maybe only for some procedural textures?

Hi lopez67,

Some of the V-Ray procedural textures have three-dimensional coordinates and can be used in the described way.
Here's the textures that do support 3D placement:


You can use each one of those and change the Texture Placement Type to 3D.

Hope that helps,
Konstantin

Interesting. Could the material get a special mark, maybe (3D)?

You have a point here.
We should indicate that these are 3D textures somehow - I'll log it.

This is great!
To me, procedural textures and OSL textures are the future. With Substance or other similar software you can create your procedural material but then you need to bounce it to create 2d maps, so you need again texture them to apply to 3d objects as a regular 2d map. This is the past to me. With 3d procedural textures and osl, inside the rendering software, you don't need to map the 2d textures on the 3d object. The importance and utility of this are incredible.

Anyway, the only ones that works here are the two noise, the cellular and the smoke....the others don't work with the 3d world texture placement...

Hi,

You might have to change the texture Repeat parameter depending on your scene:

Hi Constantin,
I'm desperately trying to create some realistic material in Vray for grasshopper bypassing the issue of UV mapping limitation. I'm trying now to use procedural textures, but if I scale non uniformly the projection, the texture doesn't follow the shape of creation (in this case some sweep along a rail). Any help?
Thanks,
Roy

Hi Konstantin

Just a fast question what is the difference using 3d map ( object space) and 3d map ( world space).?


Thanks in advance

Nice question López67

[lopez67]

Any news?
thanks in advance

Hi lopez67

I think the easiest thing here is to use a plugin for mapping. This will help in other instances as well.

Hi luisgamino2
Please check here https://docs.chaos.com/display/VRHIN...xturePlacement
There is additional info there that might help with other settings for placement

[lopez67]

hmm...this was the only reply I was hoping not to receive...lol
do you have a suggestion for the plugin? do you think will you develop it as a command inside vray for grasshopper?
and anyway, the question is still the same: what's the difference between 3d object projection and 3d world projection? the manual doesn't answer it. why is the image I've posted above the projection doesn't follow the object if I'm using 3d object projection?
Vray for grasshopper is very underestimated and not much used until now but the future in my opinion. Impossible to stop grasshopper for architecture, lol.
Anyway, thanks,
Roy

I didnt find any kind of information slavcho

I asked what is the difference using 3d map local space vs 3d map world space.

What do You mean with this in vray... what is local space and what is world space???

In the Docs. Chaos didnt explain anything about it

Hi guys,

As for the screenshot posted by lopez67:
The 3D mapping you see is exactly what I'd expect.
There is no guarantee that the texture will be distorted in the direction you want.
The distortion is based on each object's local transformation.

Object space means that the 3D texture is going to be calculated in the local transformation space of each object.
This means that if you have mapped a cube and you later rotate and translate it, the texture will not change. It'll stick to the cube.
The World space mode will place the texture in global space meaning it will not stick to objects when they get transformed.
When you move objects around in this mode it will appear as if they are floating trough the three-dimentional texture.

Hope that makes sense,
Konstantin

konstantin_chaos Unfortunatly the Object Space isn't supported at Rhino, only we get World Space always. Is there a chance to get the Object Space working?

Workaround: tested and found – the object space works for objects within Rhino blocks.
