How to do a material with 2 textures?

Rendering
1

Hello,
Is it possible to do a material that has one bitmap for color mapped as a surface, and another bitmap (with transparency) also for color, but mapped as a box?

Thanks!

Hi @Bogdan_Chipara
I don’t think it’s possible as a single material, but easily achieved using planar decals - although it’ll take a while to set up all 6 sides of the box, if they are all needed.

For Raytraced/Rhino Render you could also use a Blend material:

The blend texture is set to mapping channel and a box mapping is applied to the box.

thank you, both, this looks like what I need

Ok… I tried both.

Unfortunately, Decals have very limited settings. The Cylindrical and Spherical widgets cannot be scaled in 1 direction, textures don’t have a repeat option, missing Box widget.

Unfortunately, Blend material doesn’t work wit Enscape, not even with regular rhino render (rendered mode).

Overall underdeveloped.

Not sure what you’re talking about. Raytraced and Rhino Render support Blend material just fine, as I showed in my previous post. But just to make sure it is clear, here Blend material again with Raytraced and Rhino Render.

Switch to display mode - shaded, then switch ObjectDisplayMode to rendered for one object with blend material. Does it show?

8

Right, rendered mode is not supported yet. But you said Rhino Render, which is the render engine.

9

yes, I ment Rendered Mode - sorry

The main thing is compatibility with Enscape . But I assume, once it will be implemented for render mode it will be available for Enscape also?

10

No, it is up to Enscape to implement support for it. The material is there with the definition, now they need to come up with a way to do that for their products.

11

I can write to them. Can you give me the link to the API part for implementing this? Thanks!

What about just using a Physically Based material with a texture in the base color slot. The texture should have an alpha component, but the use alpha checkbox turned off so the basecolor still shows:

not working with Enscape either… :frowning:

14

But it works with regular Rendered mode…

15

Do we have a “falloff” blend material option in Rhino ? (Like blending two mateials according to surface normals ?) Or can we achieve this only with Vray or similar plugins ?

16

Not at the moment.

You’ll have to ask the V-Ray developers.

@can.aysan , for “blending” two colors:
Make a gradient texture, and assign it to a material color texture.
Apply the material to desired geometry.
Use planar mapping oriented vertically to apply the gradient vertically to the geometry.

18

@nathanletwory , if you don’t insist to Chaos Group they won’t implement.

I mentioned your request to @andy - he’ll be talking to Enscape soon (face to face), maybe they get to go over this topic as well.
