From a selected material is possible to know each slot type?

[alexandre_bisewski]

Hello!

Using the ShowProperties in a vray material I can get values like this:  ".texmap_diffuse (Diffuse_map) : texturemap"

I am using this function to get all TextMap in a Material selected: getNumSubTexmaps. In vray for example I have 31 slots...

With this function (getSubTexmapSlotName _matsel 1) I get the value like: "Diffuse"

But I need to get the type of this slot like "texturemap" that I can get in with ShowProperties. 

This value is a ClassOf I guess but I dont know how to get it. 

Probably I need to get a material > do a loop in all slots and test if is a texturemap.

It is possible? Thank you!

There are different ways to do what you need to do, but the most convenient is to call instances of the texturemap class of the specified target material:

tvps = getclassinstances bitmaptexture target:meditmaterials[1] astrackviewpick:on

see the Help for details

Hi Mr Denis...

Thank you for your attention. 

I tried this function many times but I can get result using it.

tvps = getclassinstances bitmaptexture target:_matsel astrackviewpick:on
		print tvps.count

Always the result is zero. 

I got the _matsel using this:

((sme.getview 1).GetSelectedNodes())[1].reference

Is strange because I can get results using getNumSubTexmaps or getSubTexmapSlotName with the same _matsel...

Thank you

I only showed an example... In your case you may have a different class of texture maps. What class of texture maps do you use in VRay materials?

[alexandre_bisewski]

I just created a vray material direct in Slate Material.  

When I try to get more info I have it:

--classof _matsel= "VRayMtl"
--superclassof _matsel = "material"

--(getPropNames _matsel)[i] = "#texmap_diffuse"

What do you want to get?
all possible slots where a texture map can be used?

not everyone, like you, has VRay..... I don't, for example.

Yes Denis, exactly. 

And now using (getSubTexmapSlotName _matsel i) I can do it, easy...

But I need to get also the map name like _matsel.texmap_diffuse...

But to get this info I need to use this function:(getPropNames _matsel)[i] but here is the problem. This "i" index is different from the getSubTexmapSlotName.

In the getPropNames I need to pass over all slots, including that slots that arent texture maps. So for example in Diffuse texture map using getSubTexmapSlotName the "i" is like 1 but to get the same slot using getPropNames the "i" is like 150...

So here is so crazy and that is why I need to get the texturemap value. So I can get over all slots and filter based on the class

I believe I understand the essence of your problem. It seems that you would like to obtain a property name that corresponds to the texture slot name, possibly for the purpose of accessing or modifying that property.

However, in the general case, it does not work that way. The name of a property is a virtual concept, determined by the developer's choice. Developers decide how to label each property and what name it responds to. To provide clarity, developers typically provide a list when asked about the available properties (showProperties).

In any case, it is more appropriate to utilize the setSubTexmap and getSubTexmap methods by passing the desired index, rather than assigning values directly to properties based on their names.

Man, you are really good...Unbelievable. That is the exactly what I want.

But I get your point and I will think in my objective little more. 

I have some doubt about getsubtextmap baucause only return different from unfinined in the slot that I have a bitmap map attached. If this function at least give us all the texturemaps slot in the material will be nice...

The type of a texture slot is unambiguously defined as TextureMap. However, there are multiple TextureMap classes available, and the specific class assigned to a slot can only be determined once that slot has been assigned.

Once a slot is assigned, it becomes an object entity known as SubAnim. At that point, we can identify the type (subclass of TextureMap) associated with this entity.

The texturemap slot is akin to a watch pocket in a vest - it has a specific purpose: accommodating a watch or nothing at all. While the limitations of a pocket are dictated by etiquette and common sense, the restrictions of a texturemap slot are defined by the data type itself. It's all about adhering to the definition. 😉
