Alphamap ..

[chicagobob123]

I have something that three js uses called an alpha map but I can not find an equivalent in the babylon world. Its a black and while alpha channel map that is used with a UV map. Is there such a thing? I know there are bump maps. 

I saw nothing like it. 

Thanks,

Bob

You can try ambientTexture or opacityTexture, depending on what you are looking for.

So far this did not working for me. Tried it and ended up with crazy results. But that could be how I am using it. Is there anything that shows detailed information for doing this with UV maps?

Can you share a playground with what is not working for you, and what are you expecting to have ?

Here is an example on how to use textures: http://www.babylonjs-playground.com/#1MFDDU#1

I only have so much time so I gave up on it. I just combined the UV image with the alpha image via photoshop and used that.

It was for my ThreeJs importer I have been working on. Which I have pushed as far as I am going to. 

It works pretty easy although there is some manual things to do to get it to work. 

Place the name of the model as in import. 

 <script src="models/StraddleCarrier/StraddleCarrier_StructureB.js"></script>

Modify the model making by adding Var name of model at the start of the file. 

Then you load  it. I tested it for UV mapped models. Thats about it.
