This is my scene PG and I am now using shaders to make the model transparent；But now I seem to be having a bit of a problem, and I find that my model textures are very messy in the scene,

The UVs of your model do not look like they fit with your texture.
I don’t know what the problem is yet. My texture is implemented with one of these textures, but it seems to be in the wrong place on the model
yup, the texture is applied following uv values: UV mapping - Wikipedia
Hence why the issue probably lies in there
I feel like I have a problem with the edge light calculation, but now I’m not entirely sure if it’s the texture
You should consider using literal quotes
``
so that way you don’t have to keep concatenating your lines and doing carriage returns.
Sorry, I was wondering if BBL has an API for rendering mesh lines of models, not wireframe
What do you mean by mesh lines of models ?
What you show in your picture looks like a wireframe from a tesselated mesh mixed with an opacity fresnel of the same mesh ?
是的，他这个是用three.js实现的，内部的api
EdgesGeometry
EdgesGeometry
LineSegments
What should babylonjs do
@塞巴万绝地议会
Maybe @Pryme8 would come with an amazing custom shader ???
Or @nasimiasl 
?
hey let me see what we have before …
yes thanks
don’t worry you get it let me do
