More transparency issues

I have my material with these settings but I get transparency issues. Any ideas what I’m doing wrong?

mat.diffuseColor = new BABYLON.Color3.FromHexString("#7fcdff");
mat.backFaceCulling = false;
mat.transparencyMode = BABYLON.PBRMaterial.PBRMATERIAL_OPAQUE;
mat.hasAlpha = false;


Thank you!!

Do you have a playground?


Hi @Givo,

If you click on the mesh in the playground and select option 2,3 or 4 and choose another colour, as you rotate you can see transparency particularly from above and underneath.

HMM. I see just this.
What do you see?

Yes, sorry that’s correct, I loaded just part of the model.

I’ve loaded more of the model in this one, might be easier to see:

Ah, ok. (I forgot that you could choose what meshes to load)
I see your issue.
I can see the shadows through the car. I don’t want to ping random people, but I wonder if @Vinc3r could help with this.

ah cool, so it could be something to do with the shadows.

It only seems to happen at the front and the back of the car so it could be something to do with how I’ve built the model.

How are your normals?

There might be a few weird things going on, the back of the car is probably better than the front. A while ago I may have accidentally removed some edges and not sure how to put them back, these might be leaving gaps.

Is the 3ds Max? or Maya? I primarily use blender but what if you simplified the geometry to have no gaps?

make sure your normals are all pointing the right way.

If you wanna swing me the 3d model Ill check it really quick this morning.


Blender, I think you’re right, I did try to before but got in a mess after separating the parts into layers
