Hey RODPV, :) Cheers for the post - will give it a go when I have a moment. Essentially, I did the same; just used a different method to get the IDs done whilst faffing around with this bug. Aforementioned above, I just baked the Materials to Diffuse colour, instead of Vertex Paint projecting and exporting to XNormal.
I`m also using the assign vertex color method in 3dsmax and had the same issues initially. It`s been a while so I don't remember how exactly I arrived at this solution but this is what I use now to get it working: place a skylight, set the sky color to pure white. use assign vertex colors with default settings…
Hi Polycount, I prefer using XNormal to bake my textures, and require a Colour ID texture. Therefore, I'm baking one from my high poly object. Inside of 3DS Max 2016, I have assigned various materials to different parts of the high poly object, acting as the Colour IDs. The screenshot below shows my high poly object with…
If you're just trying to make a colorID texture, you can bake a "diffuseMap" in max and it will use the object colour as the colour of the render. eg you wouldn't have to move the object colour into vertex colour, it should just work.
