solved Model flip issue

[syed samoon]

Hi Everyone,

      I was stuck in modelling. when i use 3d model of unity and then i was converted it to babylon file using 3ds max.

but sometimes in rendering the model will be look like image below.

 

 

Anyone know why it is happening to me

Is it a single model? If so you are facing a face ordering issue

but no problem, we've got you covered. Just call mesh.material.alphaMode = BABYLON. Engine.ALPHA_PREMULTIPLIED

 

Also, based on how looks your mesh, I suggest not using opacity texture (which force full transparency) but instead diffuseTexture with alpha

 

Good reading about alpha and transparency: http://doc.babylonjs.com/resources/transparency_and_how_meshes_are_rendered

Thanks but it is not fixed yet

there are images given below.

there is no changes in script it is a single mesh 

but sometime the lamps bottom will be viewable and sometimes it will be non viewable(in correct manner).

 

there is no changes in lamp's X & Y position both are in same place

the floor is transparent in sometimes 

 

can you know what is the reason for this? why it is happening??

yes  @Deltakosh  it is a single model.

 

https://assetstore.unity.com/packages/3d/environments/sci-fi/sky-city-lite-65679

 

the above link is unity pack of this model

 

i was download and duplicate the platform and merge (Using 3DS MAX) them to get big platform like this.

And the i was exported as .babylon file

You should try to not apply transparency on meshes which are not transparent. Try to decouple them in 3dsmax

Is there anything wrong in lightning and camera

my script is given below

this.base.camera = new BABYLON.FreeCamera("camera", new BABYLON.Vector3(0, 0, -30), this.base.scene);

this.base.camera.maxZ = 1700;

this.base.camera.attachControl(this.base.canvas);

this.base.camera.speed = 2.0;

 

this.base.camera.setTarget(new BABYLON.Vector3(0, -2, 0));

 

 

// Hemispheric light to light the this.base.scene

hemi = new BABYLON.HemisphericLight("hemi", new BABYLON.Vector3(0, 1, 0), this.base.scene);

hemi.intensity = 0.5;

var directionLight = new BABYLON.DirectionalLight("DirectionalLight", new BABYLON.Vector3(0, -10, 400), this.base.scene);

directionLight.diffuse = new BABYLON.Color3(0.8, 0.7, 0.6);

directionLight.specular = new BABYLON.Color3(0.9, 0.8, 0.4);

directionLight.radius = 1;

directionLight.intensity = 0.5;

i didn't use any transparency maps on meshes

i used 3ds max and applied only diffuse map

try to turn of the backfaceculling, something like

mesh.material.backFaceCulling = false;
//or
mesh.material.subMaterials[0].backFaceCulling = false;

There must be opacity support enabled somewhere...can you share your scene somewhere on a website so we can see it live

If I well understand, you have imported FBX files from Unity package to 3DSMax, then export this scene to BJS.

In 3DSMax, have you cleaned your meshes before? I talk about xform, transform & scale reset, pivot, etc (I have a maxscript to automate this if you want).

I don't understand, have you tried it and it doesn't do anything, or will you try it and haven't use it yet ? (and do you talking about my script?)

If you don't want use the maxscript, you just have to do that:

[syed samoon]

i was done this same

[V!nc3r]

Can you share both max files and BJS scene? It looks like there nothing available in http://samoonaski.000webhostapp.com/?dir=babylon scene/

I've asked if it was possible to get the 3dsmax file, plus an online demo (not just the .babylon file).

Hi Everyone,

      This issues was fixed.

 

 

thanks to all

 

Reason is 

when i instanciate/copy mesh using 3ds max. it will happen

when i clone the mesh using script it will happen

 

but i don't why

 

anyway once again thanks to all
